Repairing logic board by hand?

My screen has succumbed to the iMac pixelation disease. Has anyone figured out what parts actually fail on the logic board which cause this? I would like to see if I can replace them myself.

Hello and Welcome to Discussions.I really don't think you're going to get anywhere with this. Even if you posses excellent soldering skills you wouldn't have the chips to replace and if you linger on that board a split second too long you've fried it all.
Could you provide more info on what you've tried and exactly was the issue is so we can see if something more realistic could help.
Cheers

IPhone 5S 32GB Logic Board Repair

So several months ago I attempted to repair the cracked screen on my black 32 gb iphone 5S on my own. It did not work out. I ended up breaking the logic board and now the phone is basically unusable. I've been using my iPhone 4S for the past few months and it ***** so bad. I just want my 5S back but now apple won't touch it and no one offers repairs for the logic boards on the 5S that I can find. Anyone know of a solution or someone who offers the service. Because I can't stand the crap battery on the 4S and I miss my 5S I had only had it for like, 2 months.

I know of 2 services that repair logic board damage depending on your issue and your location in the U.S. One is eDigitalNY which is on the east coast and offers their repair services on eBay in addition to their website. They guarantee their repair work. Just ship them the logic board (shipping to and from is included in the repair cost) and they will fix it. If for some reason your board is "toast" and can't be fixed, they will refund your money. The second option on the west coast is The Repair Stop. Like eDNY, all repair work is guaranteed. TRS is a bit pricier but they are the go to guys for water damage repair, an area of repair from which many others shy away.

Logic board died twice

Sorry in advance for the long post.
In may right before i moved to Venezuela, I bought the then very new intel mac book. I used it for a month, and one day it wouldn't boot. I brought it to the mac store i was surprised to find in my city, and they agreed it was under warranty and essayed to fix it. It took two months, during which they said that they didn't have the necessary parts (logic board) on hand because the intel mac book had not yet launched in South America. I wasn't happy about it, but it seemed plausible.
Fast forward 2 months, and it happens again. I brought it in for service on Nov. 11 and still don't have it. Apparently the part is held up in customs. They are unflaggingly polite and seem genuinely to want to help, but they just can't get the part. Customs is, of course, a corrupt bureaucratic nightmare, but still. I asked if it was a matter of greasing a customs agent, but they don't know as they rely on a courier service. I asked if i'm the only person in this boat, and they said no. I asked if i could just get a new one, and they said no. I asked if they could cannibalize the part from one of their unsold stock and replace that if it ever comes in and they said no. I didn't really expect them to go for either of those options, but I tried. To be clear, they were very helpful and showed me the incident history, that they'd checked the machine and ordered the part on nov 10 and it had shipped on the 15th, so i don't have any problems with the macstore employees, except the fact that I always have to be proactive about finding out what's going on.
What happened the first time is that the hard disc had been corrupted, according to them, so i got a brand new installation on a 60gig drive and $50 credit, since they didn't have a replacement 80gig. I'm sure that's what's going to happen again, so is it too much for me to demand that they give me a new one, as I suspect a bad motherboard is somehow burning out these logic boards, because reading through here, this doesn't seem to be a common problem. I feel particularly burned as an early adopter, who has only been able to use the thing 3 months out of the 8 i've owned it. I'm very afraid this is going to happen when i'm out of warranty and then i'll be SOL.
In Mid December a friend brought me down old powerbook, a g4 256 meg, so i'm online, but it's nowhere near powerful enough to do what i need, and i don't want to spend upgrading a stopgap.
I've been looking for a way to ask apple usa about this, but none of their online support options seem to fit and i'm not going to pay international rates to spend hours on hold.
This is certainly the last time I buy the first rev of anything by apple and barring a quick satisfactory resolution the last time i buy anything apple at all.
Again sorry for the long post and if this is not the appropriate forum, but i don't see any better.
thanks,
chris

I was sympathetic to your story until I got to your
conclusion, which just doesn't seem to follow from
the facts.
OK, what i should have been more clear about is that this is an _Apple Store_, huge Apple logo out front, employees in black shirts with white logos, the whole bit. My support incident is in the apple support system. Apple knows i've been without my new computer for more than 10 weeks, and they've done nothing about it. Noone _at Apple_ is looking at the warranty incidents and saying Gee, customers are without their new computers for months at a time. Perhaps we ought to a) address the problem and b) contact the affected customers with updates, condolences, gift certificates, whatever.
Seems to me your biggest problem is that you live in
a country hostile to the US, which probably explains
why shipments from the US are so massively delayed.
The politics are irrelevant, trust me.
Why does there have to be a shipment. Why don't they have the part? They are selling these exact same computers. They aren't saying, 'Oh, and if something goes wrong, there's a monthslong turnaround on any repair requiring a part. It took 2 months the first time. why didn't someone immediately order a small pile of these things, and then keep enough inventory in stock. Why are they ordering parts one at a time internationally?
Why don't they have enough parts?
A: They didn't figure the defect rate correctly and stocked too few. Apple's fault.
B: They did figure the defect rate correctly, but gave customer service the shaft in favor of sales. They don't have a 3 month wait for new ipods, i can tell you that. I could have bought the exact same model of computer they can't fix anytime in the last 10 weeks. Apple's fault.
C: They didn't do due diligence on customs etc. before opening a store here. that seems unlikely. And, again, they get the video ipods through customs somehow. but that would still be Apple's fault.
D: They just can't manage inventory. Guess who's fault.
Why hasn't someone who can authorize these things been made aware and made a decision to use the unsold new stock to either fix or replace my computer. It has been more than 10 weeks.
Bottom line is they sold me a computer and told me i could get it fixed at any Apple store worldwide. They literally warranted that was the case with their warranty. They are unable or unwilling to fulfill their obligation. They have failed to live up to their end of the deal. They took my $1300 and i have no computer. Does it follow now that I might swear off the company, although I love the OS, besides the fact that they sold me hardware that's died completely twice in it's first 5 months (of calendar time, 3 months of actual use?
Oh, and describing Venzuela as hostile to the US is like describing the mouse in the tank as hostile to the boa.
It also seems to me that it would be worth your while
to get in touch by phone or by letter with US Apple.
Use Skype to call, or send a letter. You might have
been able to arrange for your friend to bring you a
new one, or at least the logic board, if you had
made the effort to contact Customer Support earlier.
So what do you have to lose by contacting them now?
Just a little money, lots of time and patience, assuming this old powerbook is more adept skype than garageband. But there's no way I'd ever ask a friend to carry a naked computer board through x ray machines in 2 countries to help an international corporation extralegally subvert customs. i'm old-fashioned that way.
Sorry if this all seems a little heated. I'm not mad at you, I promise, but i am awfully frustrated at my treatment by apple (the corporation and not the kids at the store).

What is the part number for my MacBook Logic Board?

I have been searching through all of the Apple forums to help me with my issue. My issue is not knowing the partnumber for my MacBook Logic Board. The sticker that is usually found on the ram slots is NOT there.
The information I have for my Mac is:
2.4GHz/2x1GB/250GB/SD
EMC No.: 2254
Serial No: W8846MGM1AX
I hope someone in the community can help me.
Thanks Ahead of time.

The wegenermedia reference relates to some earlier positive results others mentioned some years
ago, and due to that, I sent an iBook computer to them, in a padded box (over-engineered) that I
made, for diagnostic repair service, and it returned with stickers over the screws that said their
warranty would be void if the tape were damaged or removed. I felt sure enough of their work that
I later sold the computer to an 80+ y/o some miles from where I lived, and chose to give him free
support for two years. That means since he never had used a computer, and saw an ad I put on
a bulletin board in that town and chose to reply to it, I even went as far as helping set up printers
and other things he had never done, at no additional profit to me. The iBook was a complete kit
and included original box, plus later OS X and extras, at below other location retail.
I've been in contact with them about two other computers I have, one is an aluminum PowerBookG4
and the other a MacBook1.1 13-inch 1.83GHz first-model, each has issues. The MB1.1 is better, &
it only needs some parts to fix two issues, but it runs well. An occasional winking display, that does
best if left sitting with lid open; and by use of iStat Pro, I see odd information from the CPU temps on
one of the two cores in the processor. Sometimes, it says the core is sub-zero °F, other times hotter
than the other one. And also, it may disappear from the reporting to iStat altogether. So that may be
as simple as a need for new thermal paste if the CPU could be so doctored. They will inspect and
test an item before a firm cost estimate is arrived at. They've also workstations to repair logic boards.
So I'd be willing to bundle up my early MacBook1.1 1.83GHz and send it off for a $200 service, since
once it is opened most issues can be dealt with on the spot, and it would be returned with warranty.
Since my example is a clean one, it may be worth that service. It has 10.5.8; could run 10.6.8 OK.
Anyway, the discussion is a bit afield from the OP topic, except there are experts who can repair an
original logic board; some prefer to see and test the entire machine. Others may swap out the board
for one they've already serviced if available, for turnaround-time sake. They offer older refurbs, too.
Between the sales model number and processor version it should be easier to locate a replacement
for the original post's questionable part issue. Some devices had additional part numbers that may
work, depending on the length of product run and changes in manufacture over the duration.
{Seems to me you'd gone from using Macs awhile, to PC, and were in state of ID awhile, btw.
And the reference email I have, is your first + last name at gmail.}
In any event...
Good luck!

Is it worth trying to get my MacBook Logic board fixed?

I have a late 2008 MacBook unibody, 2GHZ, A1278, suddenly about 2 weeks ago, it just crashed and died (after over 4 years of beautiful service)
When I hit the power button, I can hear the HD power up, but then power down again about 5 seconds later
I brought it to CompuB (Apple authorised workshop in Ireland), and the guy said the logic board was gone!! he wasnt any more specific about what happened, just that it would cost around €1000 to replace.
the visit to CompuB cost me €69
I've seen/read that some places can repair Logic Boards! has anyone any experience of this, would it be worth taking a punt? I dont want to fork out another €50-€100 just for some guy to tell me it's totally fried!
I've since upgraded to a new 21" iMac, so it's not essential the MacBook is fixed, but if I thought I could spend €200-€300 and get it working again, I'd go for it, as I really loved it!!
Apologies if this has been brought up before, I'm new to this forum, and forums in general!
Cheers.

Thanks for the reply FatMac
I agree with what you said,
The OS is/was actually Snow Leopard (I think 10.5.8 was Tiger, I had updated to 10.6 a few years back)(my mistake for not saying this),
I had also upgraded the RAM about 6 months ago from 2GB to 8GB, and gained a massive performance improvement - could this have been a factor in the Logic Board's demise?
The iMac 21" will now be my primary mac, however it's a late 2012 model, so the RAM can't be upgraded (unlike the 27") (at least that's what Apple told me when buying it) (a decision I will probably rue in the future)
I've also got a 2TB TC for back up, and I have loads of external HD's for storage( 2x 1TB, 1x 2TB, 1x 320gb).
I've also just yesterday purchased a Mac Mini, to use an an entertainment system in the front room (I have a spare wireless mouse/keyboard now, so it would be a shame to not utilise them).
So, if the macbook was fixed, it would probably see little use, but would still be used from time to time!
as you mentioned, a connection is formed with a mac (sounds silly, I know, but it just is), and the thought of never seeing her light up again is an awful thought.
I'll hang back for a while, and see how I get on, I got a quote from a place that say they regularly repair macbook logic boards of €250 to repair it, so I'll see how I get on, and if I happen to have a spare few €€€'s in my wallet some week, I might drop it in to them.
Thanks.

Logic board repair extension

I have an iMac 1st generation I purchased A little over 3 years ago. About 2 weeks ago I started having video issues with my Mac where the desktop freezes, sometimes goes blank and other times I have horizontal lines going across the desktop. I thought it was a video card issue but after doing research on the support page on Apples website I found that it may be an even bigger problem than a video card. I have read that there have been may problems with the logic boards in the 1st generation iMac's. Today was the soonest I was able to visit my local Apple store only to have the genius affirm my suspicion.
I did notice that under the support page, on the lower right hand corner, in small print that there is an issue with these logic boards. The repair extension program leads all of us to believe that Apple acknowledges the predicament many of us are in now, that we have bought a faulty product. The genius at the Apple store told me that I was out of luck and that there is nothing that can be done with getting my computer repaired under the extension program. He told me that if I would have brought my iMac in 2 weeks ago when the problem occurred that he could have honored the extension program but now it is too late. My computer was 3 years old on Jan 27, 2008. I don't understand why he would have allowed the extension program at 4 weeks beyond the 3 year mark but not at 6 weeks? When I tried talking to him about it he then told me that Apple doesn't even do the repair extension anymore for the logic board. Its either you do or you don't but don't try to blow me off with lies so I have to pay for an expensive repair. He quickly changed his answer when I told him as of yesterday the repair extension program was still posted on Apples website.
Also, I would like to know why the 1st generation Imac'ers were not advised of this problem? I now have a 20 pound paper weight sitting on my desk, unless I opt to pay over $500 dollars for a repair that Apple has said was faulty from the get go. Apparently its only a matter of time before they all start to have issues.
Back to the Apple store visit. When I pleaded with the genius 1 more time he told me that because I didn't purchase the Apple Care Plan at the time I purchased my iMac I should have expected to pay for a high cost repair bill eventually. Seems he doesn't have too much faith in the products he is supposed to be endorsing. I walked out of the store feeling like I was lied to, and belittled because of his demeaning attitude towards mine and many other peoples situation with these 1st generation iMac's. Customer service does not seem to be his line of work.
Has anyone encountered this situation where even though they missed the 3 year window for a free repair extension they were still given the repair at no charge? I have really lost my faith in Apple. Not only does Apple have a crappy way of dealing with faulty products, they have some pretty rude people working for them. I was pretty much told that because I didnt pay for the Apple Care Plan I'm stuck. Although, had I purchased it Apple Care Plan they would have given me the free repair even though I missed the repair window of 3 years. Windows is starting to look appealing to me again. Your thoughts are appreciated.
I would like to file a complaint about my experience at the Apple store and would like to know if there is something we can do to honor the repair extension program? I was a loyal Apple customer until I had to be put through a genius lashing who needs to have his behavior attended to. I will be looking forward to your reply.
Thank you,
Val Lutyj

I believe that the employee treated you harsher than he should have. In my eyes, there is always a more appologetic tone to take with a customer. The reason the rep was not eager to help is basically because of what he said, repairs are bound to happen. I work in a non-commision based Apple Specialist environment and we try to get this by our customers as much as we can... it is going to happen. Applecare is not Best Buy trying to take more money from you. It is used to help them cover repairs that happen YEARS from the purchase date. We used to have a tech here that would flat out tell the customers that said no "Don't come crying to me when your computer breaks and you pay for it". I still believe that he was harsh in the way he said that but I find myself wanting to say the same thing.
Apple computers will always be built in a much finer quality, but no matter what you do, they will all break. Thats just technology. When your parts break and a higher percentage than normal, you need to stand by the product. Apple did so with a 3 year repair extension... but should not have limited you so quickly.
I am almost certain that if you call them directly and plead a little more, you will get your results. You are a loyal Mac user and a returning customer for when it is time to get rid of the 1st Gen -soon I hope ;)-

How to send in for logic board / HD repair?

Not long before my trial AppleCare expired, my MacBook Pro started doing very strange things, freezing, crashing, making grinding noises, etc. After reporting the results of Disk Utility and a hardware scan to AppleCare, they gave me a case number and said that I most likely needed both a logic board replacement and a hard drive replacement, and that if I had further trouble, to take it in for repair.
Well, the local Apple Store's Genius Bar has been entirely booked up for two days now, and as my AppleCare trial has expired (though I'm under warrantee), I can't call Apple about it.
Can I simply walk in and drop it off? Do I mail it to Apple myself? I've never had to send a machine in to Apple, but it's seemingly not as straightforward as I thought.... how long might I expect my turnaround time to be?
MacBook Pro, 2Ghz Mac OS X (10.4.7) {dying fast}

... as my AppleCare trial has expired (though I'm under warrantee), I can't call Apple about it.
There's really nothing "trial" about it, although I can see how it could be perceived that way. What expired was your 90 days of free phone support for any issue with your MBP, but since, as you know, you still have a one year hardware warranty, you still have free phone support for warranted hardware issues.
See Is phone support and warranty service free? for details.
As Kappy indicates, it's a very straightforward process. If Apple determines that you do have a hardware defect, they'll arrange for a shipper to drop off a shipping box and take it away when you've packed your MBP, and then they'll ship it back to your door when the repair is complete.

IMac G5 (2004) logic board and the repair extension program

Hi,
I know that there are tons of topics about logic board/power supply troubles witht the first generation G5s, and I'm sorry to start yet another new thread, but I still have some questions about this issue.
I have a first generation iMac G5. Long story short...when I first got it the computer would shut itself off sometimes after I had put it to sleep. When I would try to restart nothing would happen, but usually letting it sit unplugged a while would solve the problem (occasionally when I'd restart a different start up noise would sound and the white light would flash quickly). It happened so randomly, that I just lived with it, blaming the problem on my dorm network, or a power failure. A few days ago I tried to start the computer up and nothing happened (just a VERY faint sound like a clicking or ticking or intermitant humming...definatly electrical sounding). I unplugged it overnight, but the next day still nothing. I decided to go through the troubleshooting steps Apple lists online. The internal power button could not start it up and the second LED does not flash, which according to Apple means the logic board needs replacing. Luckily my serial # is covered by the Repair Extension Program, and I'm bringing my computer in tomorrow morning to be fixed (just in time for back to school).
I have become concerned, while browsing the discussion topics, that this fix may not be permenant. I've read a few posts that claim that they are on their third Logic Boards, and this kind of scares me. My parents bought me the computer (our family's first ever Mac) and did not purchase the AppleCare extended warranty (they had heard how reliable Macs were...hmmm.) I didn't even know that I could purchase AppleCare after-the-fact until it was several months after my 1yr warranty expired. I do appreciate the fact that Apple recognized what seems to be a common problem with this generation of iMacs, but I wonder why they did not contact the owners of these machines to let them know that the problem and repair extension even existed.
So I guess my real question is...Does anyone know if, after this repair Apple will replace the logic board if it dies again? Is there a limit to the number of qualified repairs you can get through this Repair Extension program? Also is there any other Extended warranty type thing I can purchase after my 1yr. warranty is up.
Sorry the post is so long...I'm just scared about the fate of my beloved Mac.
iMac G5 (2004) Mac OS X (10.3.9)

Oh man, am I actually relieved reading this thread. Just took my baby (iMac G5 first generation) in for repairs today, not knowing what was wrong with it. Luckily my serial numbers are in the range, so I'm crossing my fingers that they're going to cover this.
Brief synopsis of what happened, in case it differs from anyone else's
About a month ago, my iMac started to not wake up from sleep mode. Instead of waking up, it would just shut itself off. This continued for about 2 months, with me thinking nothing of it. Then, instead of shutting itself off, the computer would restart when I attempted to put it to sleep.
Then, last night, I was surfing the net and all of a sudden the power just failed. No noise, no "grey screen", we're talking like a millisecond later the screen was black. I treid unplugging the machine and then plugging it back in while simultaneously holding the power button to reset the PSU and still nothing. At that point it was about 1:30 in the morning, so I just went to bed not wanting to deal with it until the next day. By the time I woke up, there was a distinct smell of electrical components burning (in grade 8 shop class we used to hook up resistors to the voltage generator and crank the juice up until they fried when teach wasn't around, so I distinctly remembered the acrid stench :P)
I opened the back up and did the LED check, and #2 wouldn't even blink. So I took it in and they said they'd have to get back to me and that's where I stand now.
The thing that concerns me is that if some of the components fried that there may be possible damage to the motherboard etc. Luckily I'm not too worried about the hard drive because it did still boot up and all. People that have experience with this, what usually happens with files on your HD after a logic board replacement? Are they usually fine?
The other thing that concerns me is that apple has made no effort to contact me, and it will be 2 years after the purchasing date come November 1, 2006. I'm lucky that I caught this now before it was too late.

Should I repair an Ibook logic board

I can have a 12 inch ibook 1.2ghz if I pay to repair it. It was just 14 months old, had been treated with great respect, when the logic board failed. Needless to say its owner had not purchased any extended warranty. Its owner purchased a new macbook and put the ibook in a drawer because he decided it was not worth the repair. I would use this ibook to replace my old Powerbook 3400c that died finally. I see on the forums that logic board failure is a problem with ibooks and that many people replace one only to have it fail. My question is whether it is worth replacing this ibook logic board? Is there a generic problem with the reliability of these logic boards, so that subsequent failure is a hit or miss thing? Or does their failure result from other factors so that an ibook that has one logic board fail may have an underlying cause that will lead to subsequent failures? Is this computer worth saving?

I see on the forums that logic board failure is a problem with ibooks and that many people replace one only to have it fail.Although there have been some failures the absolute majority of iBook G4 users have not had any type of logic board failure.
Is there a generic problem with the reliability of these logic boards...
No
Is this computer worth saving?
You will need to look at the cost of replacing the logic board versus buying a new/refurbished iBook G4 or new MacBook.

Need Info to repair broken power switch connector on logic board

Hi folks,
I had some bad luck this week. The power switch connector broke off my daughter's Ibook logic board during a HD upgrade attempt. Unfortunately, it pulled enough of the etch that I can't determine where the connections use to go.
I would like to salvage the board. So, if anyone has access to a schematic for the G3 Ibook, 14" 900Mz logic board, I would appreciate some info about the circuit. Specifically, to what components does the switch connect. I already identified one side is grounded and the other side is pulled up to 3V through a 1K resistor, but that etch also went somewhere else. I suppose the gate of a FET transistor. Any help would be greatly appreciated.
Perhaps someone with a dead logic board could trace the circuit with an ohm meter.
Regards,
Spencer

Hi spencer,
Apple doesn't make circuit diagrams available, sorry. I've done or had done component level repairs of iBook logic boards before, usually to re-attach connectors which have come off, but unlike yours, these ones have all come off leaving the trace on the board.
The fact the traces have come off isn't good, as you can probably tell. It's also a 4 layer board, so where the vias go is important. I have a couple of dead logic boards from 500,600 and 700mhz iBooks. The 14 inch logic boards are essentially the same as the 12 inch ones. These pictures are of the area of a 700mhz logic board.

Water spilled on MacBook, need to replace Logic Board--worth it to send it in for total repair (where it will be like "factory new")?

Thursday--I spilled water on the keyboard of my MacBook Pro 15", and it immediately turned off. I unplugged it from the charger and turned it upside down, and then began to dry it off the best i could with a towel while letting it drain. Then I took it straight to the Apple store on my campus, where a technician removed the back, took each part out separately, and then dried it/the parts out the best he could. He advised me to wait a day or two and then try to turn it on.
Saturday--I used a hair dryer on low heat to help dry it out the best I could, and then I tried to turn my computer on. It wouldn't work, but when I plugged it into the charger it did turn on. The screen looked a little waterlogged and was flickering slightly. I took it back to the store and they said that their technician would look at it.
Wednesday--I went back to check on the status of my MacBook, and the guy presented me with two options:
I can replace the Logic Board for approx. $500-600 and be done with it (and eventually the moisture in the screen, which is clear as ever now, will dry up?)
or
I can send my entire MacBook back to the factory for replacement/repair of anything that might need fixing for around $1300-1400.
I am currently on my MacBook now, and it seems to be working just fine (although it has to stay plugged into a power source because the battery won't charge)...
Money isn't an issue here, yet (it was bought with an AmEx and is covered with that warranty up to a certain dollar amount), but my question is this: Is it necessary for me to replace my Logic Board, if my computer still seems to be working--or will I end up seeing issues down the road if I don't and Should I go ahead and send it in for a full factory repair?? Is it really worth it??
Thank you!

It would be best to send your MacBook in for a complete overhauled, this will save you time and trouble in the near future. I am sure you have some items internally that will continue to corrode and render your MacBook inoperable some day soon.

Repair of logic board

Hello. Attempted to add 2nd hard drive to mid-2011 Mac Mini 2.3(i5). Unfortunately, IR connector to logic board broke. Company that sold me 2nd hard drive & video instruction(via online) stated that they could not repair. Is this something that Apple can fix or it it lost and I have to purchase a new Mac Mini? Thank you in advance.

Talk to Apple Genius Bar. They will tell you repair cost.
No one here is a certified repair tech who is actually loking at your unit, so we can only guess at the cost.
Good luck.

New Logic board? possibly repair?

Recently some water was spilled on my macbook, damaging the high voltage. Apple quoted me a price that was out of this world, my local CompUsa quoted me a 650$ price, and dt&t repair quoted me 550$, im on my computer right now. It works fine, the back light just flickers on and off.
What should i do?
The Tech guy At compusa sad they Mark up prices by 20% so if i could find the part i could buy it myself.
isn't there a cheaper way to get this one problem repaired?
its not a 500$ problem. maybe a 200$ problem?
(also could i possibly get a 2.2ghz logic board to stick into my macbook?)

Can Logic Boards be Repaired?

I have a failed early 2009 24inch 3.06 GHz with ATI 4850 512 MB graphics.
The hard disk and all other parts are fine, and the machine only boots in safe mode.
Everything has been tried, plus sending to an authorised Apple support service.
I am informed that the Logic Board has failed and face a huge bill to have it replaced.
My questions are as follows.
1. What has failed?
2. Can it be repaired?
3. What is the Apple experience of this?
I have noticed I am also not alone with this problem.
Logic dictates if the Board has failed, a replacement will also fail.
So what is the real fault, and what is the real repair of it?
Or is this a fault that is too complicated for Apple to have a fix other than replace it and repeat the problem.

The logic board is a printed circuit board with hundreds capacitors resistors and similar small components soldered onto the fine copper strip.
Additionally there are sockets for RAM drives and CPUs, GPUs etc...
One of the common issues with PCBs in general is solder bleed shorting as a result of heat build up- If this happens its terminal !
Apple have diagnostics that can identify a fault and provide a reference number however frankly if the fault IS on the board (broken copper strip solder bleed or tiny resister for instant) its remains easier and more cost effective to replace the board than attempt to strip the board out - bench test find fault replace and reassemble.
Replacing PCBs is industry practice.
Those fault diagnostic results ARE analyzed by Apple for trends and to identify quality issues.
Lowluster is quite wrong in saying that Apple are secretive if there is an identified design or engineering issue.
In fact there have been such problems in their products and they HAVE had programs to replace those FREE and after normal warranties such as a problem with iBook logic boards faulty MacPro graphic cards,Macbook damaged bottom panels and battery swelling are some.

IBook G4 logic board repair

iBook G3 had a logicboard repair program
http://www.apple.com/support/ibook/faq/
Many iBook G4 purchasers have the same problem and "Apple accepts fault for defective iBooks in Denmark"

Can other customers expect any extention program for iBooks G4 bought since 2004?
Thanks

Well that chip in question is on the logic board.
The steady deluge of complaints, and a subsequent investigation by the independent >lab Delta, led the Board to discover an easily repeatable flaw: a solder joint for >a mainboard chip would loosen with each press of the power button, invariably >causing a break in an important connection that would effectively kill the system
This is not the only bad solder connection on these boards. U28 is another one that has problems for example.
