24 Inch Intel iMac... may have bad Logic Board

What are my options if the Logic Board is bad? Is this something you can purchase? Dont have an Apple Store anywhere near me.
Thanks!

What are my options if the Logic Board is bad? Is this something you can purchase?
No, at least not from Apple. You'd have to find the logic board from some unauthorized third-party vendor.
Dont have an Apple Store anywhere near me.
You do have an authorized Apple service center in Wichita, Haddock Computer Center, on E. 13th St. N. They can handle the repair for you. There are also places, including an Apple Store, in Tulsa and Oklahoma City which might be an option.

How can you transfer files from an iMac with a bad logic board?

This is in reference to my "Nothing but a blue screen at startup!" post. He took his iMac to an Apple authorized repair shop and he was told that the logic board was shot. He has decided to get a new iMac but he's wondering about all the photos and other files he has on the old hard drive. What are the ways that he can get files from the old hard drive on to his new one when he gets it? Thanks in advance for your help with this!

Hi Eric!
roam's method is a very good one!
I don't know if this will work because of the bad Logic Board, but another way, may be to use Firewire Target Disk Mode.
The ailing iMac would have to be Firewire enabled, and you would need access to another Firewire Mac.
Good Luck!

Just got a 20-inch Intel iMac

Hi,
I just got a 20-inch Intel iMac and have couple of questions before I even open the box. I'm a PC to Mac changeover guy and I'm pretty new to to the Macintosh platform. I would appreciate your inputs to keep my system flying.
To begin with, I know that I have to upgrade my RAM to either 1.5GB or 2GB and also know Crucial is the way to go.
Apart from that, I have these questions:
1. What do I first check for after opening the box? (Dead pixels for example and etc..etc..etc..) and how do I do that?
2. Absolutely reqd tools and utilities to keep the system running at peak.
3. Absolutely reqd apps.
4. BootCamp (ofcourse) and is there a Mac OS X video conf. software that can use iSight and also can talk to PC users with any camera? Also, with BootCamp can I have multiple Windows partitions (for example having a partition for scratch disk when doing video editing)?
5.How do I make Apple DVD Player to read a DVD image (ISOs) that are lying on the hard drive? Can this also work when FrontRow is used? I have lot of personal DVDs that I bought and would like to view them from the hard drive instead of running it from the slot.
6. How do I map the Mac Keyboard to work in Windows when running on XP? Is there a Windows software that runs as a service to make it happen?
Anything else I have to do?
Rgds.

The Mac is safely nestled in a lot of styrofoam padding inside the box, so I doubt a ding on the outside can do much damage.
I like to use Onyx for running my routine maintenance. It is a great little app and it's free;

Just an idea for you. There is an entire Apple Discussion forum dedicated to Boot Camp and Windows XP.
Whereas, not everyone here with an Intel iMac has installed, tried to install or has experience with BC & XP, everyone there has or at least has an interest.
The Forum is at the bottom of the main Apple Discussions page under Windows Compatible Technology.

It seems like I just missed the interval for the hard disk replacement program. I purchased in March 2009 a 24 inch Intel iMac . How much does it cost to have apple support at an Apple Store replace a hard drive?

My hard drive continually has the floating beach ball and will take massive time to fulfill a request. And then will not boot up...so then I have to do a restore and rebuild hard drive from a past saved time machine version. Works for a little bit...then the floating beachball comes more and more...until it will not boot up again. So then I restore from a previous time machine saved version....and again it works for a day or so ... until it happens again. Now it's happening faster and faster...so I think my hard drive is dying.

Is a bad logic board due to a bad power supply?

Computer specs:
iMac G5 20", 2.0 ghz, 1 GB RAM, 250 GB hard drive
Back in October of 2008 my iMac G5 Power PC shutdown intermittently and then when I went to go to start it back up, it booted to the blue screen and hanged there forever. So, I did a hard shutdown and then waited and then booted again and it still hanged at the blue screen. I tried booting in Safe Mode, and that worked, so I had a chance to backup everything that I needed to. Then, I took the computer to my local Apple Store to speak to a "genius". They could not diagnose my computer while I was there, so they needed to take it overnight and let me know over the phone what the issue was. The next day they called to tell me that it was a Logic Board issue and that it would cost $900 to fix it. I obviously was blown away at the cost for the problem, and I could not afford that charge so I seeked out other options. I found a shop in my neighborhood that offered me a used 1.8 ghz logic board for half of what Apple was quoting me, so I went with it. Then, 9 months later (which brings us to present) my iMac completely shutdown on its own and would not start up. I ran it through some tests (LED lights on the interior) and confirmed that it was a Logic Board issue again. So, I took it back to the shop in my neighborhood and they told me that the warranty for the part they replaced had expired. So, I called Apple Customer Relations to talk to them about the issue. They confirmed, using my serial number, that I could get my issues fixed for free. They then told me about the "iMac G5 Repair Extension Program for Power Supply Issues" which was news to me. This Program ended in December of 08, meaning I would have qualified in October of 08... the time I initially brought in my computer. So, I brought my computer to the Apple Store to drop it off for repairs, and when going over the history of the machine they confirmed that because there was a used 1.8 ghz part in my machine installed from a non-authorized Apple place that they COULD NOT fix my issues now.
My question is:
Back in October of 2008 when I brought in my computer to the Apple Store and they diagnosed it with a bad Logic Board, could that have been because of a bad power supply? If that was the case, does a bad power supply cause a Logic Board to go bad?

Welcome to Apple Discussions.
The short answer is no, but it's actually more complicated than that. The original iMac G5 17 and 20 inch models were plagued by two problems: defective capacitors which affected the logic board, and an unrelated set of defective capacitors which affected the power supply. Rarely were both conditions present at the same time, but Apple decided—when they issued the repair extension authorization—that replacement of both components was a more cost effective approach. By far, the most common of the two problems involved the logic boards.
The REA covered machines for a period of three years from first sale, and ended in December of last year. Yours likely would not have been covered due to the date of sale provision. On a case by case basis, AppleCare representatives did allow coverage for machines beyond the three year limitation, but not past the end of last year.
It's not likely that you have both a defective logic board and power supply, though you may. The combination of these issues is actually found most frequently in the iMac G5 ALS models, none of which were covered by a repair extension authorization.
Your issue is a difficult one, as Apple authorized dealers and service providers have every right—and, actually, a responsibility under their annual agreements—to reject warranty, AppleCare or REA coverage for parts or labor when compatible but not similar logic boards have been placed in your machine. This is because they must exchange these parts for the part they are requesting from Apple on a like-for-like basis, and that part must be associated with your machine serial number. In trying to resolve your issue, the shop in your neighborhood actually created an additional issue for you which would only be triggered in the event of component failure. I have no idea what period of coverage they typically offer, but Apple provides for 90 days or the balance of any warranty or AppleCare extension in place at the time of the repair, whichever is greater.
Your logic board can be refurbished for $ 189.00 if it in fact exhibits the capacitor issue. That process is covered by a one-year warranty. If you are interested in exploring that option, send a message to the electronic mail address in my Public Profile and I will reply with additional information. To help determine additional information concerning your machine, please include the machine serial number if you elect to do write for more information.

Help, my 3+ year old iMac has a fried logic board

I have an iMac G5 PPC 1.8GHz 20". Within the past year or so Apple replaced the power supply as my serial# fell under the G5 Repair Extension Program. It was working fine until recently when the screen would lock up and require reboots. Now it will not even boot up. I took it back to the Apple Store and was told it had a bad logic board. The tech showed me the bulging capacitors. The estimate for the repair is a whopping 600+ bucks.
I am very reluctant to invest that much dough when I was already thinking of selling this one and buying a new Intel based iMac. Besides, I need the money for gasoline for the next week! I thought I could attempt the repair myself until I found I could not get the part any cheaper than what Apple was going to charge.
This really bugs me as I've had the computer for just over 3 years. Any ideas on what I should do? Try to sell the remaining good parts? Can it even be used as a monitor? The display is still in fine shape. Hard drive is good too (250G). Thanks in advance.
- Rick

My nearly 3 year old iMac died a couple months ago and after jumping through some hoops to get the date of purchase reset to what it should've been, I took my iMac in to a local service provider to get it fixed under the repair extension program.
I was then told when they diagnosed my computer that the logic board and power supply were both dead and needed replacing. When I brought up the repair extension program I was told that it only covered the power supply and not the logic board.
Should I contact Apple Customer Relations or should I go back to the people who diagnosed my computer and plead my case with them?
P.S The serial number of my computer falls into the range posted on the Repair Extension Program for the Video and Power Issues page, so I'd imagine my computer qualifies since it isn't 3 years old yet.
Thanks

Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

Will apple replace a faulty or bad logic board on my 2013 MacBook Pro?

I have a late 2013 13" macbook pro that has been diagnosed, by a non apple provider, with a bad logic board. The place where i took it suggested getting that confirmed with Apple. I have an appointment tomorrow at my local apple dealer...
but am worried that this practically new laptop is toast or going to be very costly since I don't have applecare!! Any help for me????

my late 2013 13" pro also has a bad logic board. The diag said it was a memory failure. I'm 3 months out of warranty and had it sent to the repair center for $280 plus tax. I don't feel like the logic board was defective I just didn't catch it in time. I tried a restore a few months ago and it worked better because i was in Yosemite beta since the developers beta and I thought the issues were because of the betas. It has constant panics and restarts but I was trying to get by until now it wouldn't turn on and disk utility said the hard drive was not mounted and it wouldn't let me restore It. maybe there are a few more people with problems then there should be so soon.

Powerbook G4 titanium bad logic board

HELP, my second computer is a powerbook G4 15" and i have been told i have a bad logic board. is it worth replacing or should i put the $500 toward a new one? Also coould a bad logic board cause other problems in the future? what happens to make a bad logic board? what does a logic board do?
thanks for all the info.
Macbook Pro Mac OS X (10.4.9)

Hi Tour Man,
Welcome to Apple Discussions.
Which model TiBook do you have? Especially if it's one of the earlier models (400-667VGA), I would certainly not spend $500 on it, as you would probably not be able to sell the entire machine for that price.
If it's a later model (667DVI-1GHz), consider what you use it for (if you have it fixed, how long is it going to serve your needs?), the capacity of the HD, how much RAM you have, whether there's a wireless card or DVD burner, the condition of the battery, whether USB2 and the many other "updates" a new machine would offer are important to you, etc.
It's not likely that a bad LB would cause other issues.
A LB (same as "motherboard" in PC land), is a circuit board on which most of the essential elements of a PB are soldered (CPU, GPU, RAM slots, etc), so when any one of these has issues, the repair is to replace the entire LB (specialized equipment is needed to work on the micro-circuitry, so it isn't something a repair shop can repair).

Display problems, bad logic board?

Hi I'm a first timer here! I have a iBook G4 14" 1.33ghz laptop I am fixing for someone. When it boots up, the screen looks like you are watching TV with old rabbit ears. You can make out the mac logo and what not, then the screen goes blue, like the basic blue background, and it looks perfect, then once the desktop comes up, it all fuzzy again. I've replaced the LCD screen, AND the lcd cable that connects to the logic board. Same results. I guess the last part would be the logic board to replace? Does anyone have any suggestions?
Here are some links to the pictures to show you what is going on...

inverter board controls brightness, the lines in your pics look more like the logic
since you have a stick of RAM, try another module or maybe remove it if you have on-board RAM
would be good to connect to the external display if the adapter is available - it would confirm bad logic board if the same lines are on the external display, it wont completely rule out the board though if there are no lines

Using external monitor with a bad logic board???

Can you use an external monitor on your ibook, if you have a bad logic board, to use it? Or is the only solution to use the shim, or get it fixed. Thanks.

Hi, and welcome to Apple Discussions.
If the graphics chip on the logic board has come loose, it won't drive the graphics to an external display, either. Sorry.

20 inch Intel iMac with 512 MB RAM: is an additional 512 or 1 gB stick bet

I have a stock 20 inch Intel iMac with 512 MB of RAM.
I've read that this computer uses dual channel RAM, so I am wondering whether an additional 512 MB of RAM or an unsymmetrical 1 GB RAM stick would be better?
Also, anyone know who makes the OEM 512 MB stick and where to get compatible memory for my iMac?

"anyone know who makes the OEM 512 MB stick and where to get compatible memory for my iMac?"
Regardless who made your OEM module, it will have a label with their name and the product specs (or at least a product number, which, on a page at their website, can be decoded for its exact specs).
Mine was made by the U.S. company Micron Technology at their Singapore factory, and the label states that the module is lead free. A similar Micron module can be purchased online from Micron's wholly owned subsidiary Crucial Technology, which is their retailing arm. Retail customers can not order directly from Micron, just as they can not order directly from either Samsung or Hynix, the other two large OEM RAM manufacturers.
"I am wondering whether an additional 512 MB of RAM or an unsymmetrical 1 GB RAM stick would be better?"
I agree that more RAM is better, will make it snappier, and prefer to buy my 1GB stick of RAM from Crucial, as I know it will be compatible for my Mac and its OEM stick (regardless of the maker) as long as I use their online Mac selector tool.

Bad logic board VS starting as target drive!

Hello,
if someone has a bad logic board on a G5, can they boot the G5 as a target drive? witht the help of another computer? (not sure if the logic board
Michel

Hi, Michel. I suspect that whether or not Target Disk Mode works will depend on what the logic board's particular problem is. If it doesn't work, be sure to remind the user that removing the hard drive from the faulty Mac will allow her to extract any data she needs from it, by installing it in or connecting it to another Mac. In many models, removing a hard drive is easy.

Can't boot G5, bad logic board?

G5 Dual 2.0 Ghz, 4 GB Ram
Can't get past blue screen unless I boot in safe mode, then I can get in.
Here's what I've tried:
5 different boot volumes, including Tiger and Leopard and a clean install
internal drives only, external drives only
reseated ram
zapped pram
zapped nvram
reset pmu
booted in single user mode, gets stuck at workaround bonjour unknown error 0
pulled out airport card, reseated airport card
tried just about everything, always stops at the blue screen with cursor
does this sound like a bad logic board or is there anything else I can try? thanks

Dear Mr. Jarrett,
Just analyzing: You're not able to boot normally from any installed system on any hard disk, but you can boot in the single user mode, are able to use AHT and the G5 even boots from the TechTool disk.
However, you do not state you installed those five systems mentioned recently, so the question is: How stable is your computer booted from a DVD (grey install disk or the TechTool bootable disk and are you able to do a fresh system install now?
I don't think your RAM chips are bad, but there could be a problem with (one of) the SATA cables connecting the hard drive to the logic board. Did you try both data cables (by using the second drive bay)? As you undoubtedly know a PowerMac cannot boot from an external USB drive, but having a bad internal data cable could also prevent starting up from a FireWire drive. And take a critical look at the four guide screws: are they well fitted?
From your description I understand you own a dual processor and not the late 2005 duo core G5. These computers are very different animals indeed.
Success and best regards,
Robbert

If my cousin in the US send me an iMac may have support in my country

If my cousin in the US send me an iMac may have service/support in my country? only NOT have warranty? configurable iMacs may ordered only from Apple web site shop in the US? SOLID STATE DRIVES for iMacs may ordered only from Apple web site shop in the US?

Hi NdeWet,
The Adobe ID should be of the same country where redemption codes were bought or else you will get the same error.
