Bad VGA Board

I had been having problems with severe texture thrashing in games and have tried several things to fix it. Finally, I installed a new board and it fixed the problem. The first board stopped working in 3d games.
What can I do about my MSI board? It is 5 months old and the reseller won't fix it.
Any help would be appreciated.

Satellite P200D-11L - VGA Board is dead

Hello,
My VGA board on my Satellite P200D just died. It has been overheating for a while with several sudden shut downs but I have got the final one. This model has very bad cooling, the design was very underestimated. I thought there was dirt inside but when I took it apart there were none. It was clean. The cooling paste was gone but clean.
Does anybody know what video card is compatible with my laptop and where can I get a cheap replacement ?
My laptop serial number : Satellite P200D-11L, S/N: 97397677K
My VGA board details : VGA BOARD M76 256 S/N: K000056620
Thanks for any help.

Hi,
I am sure that for this model there are several option in terms of vga card but I do not know where I can get this info.
How do you use your laptop ? what application are you running? are you gaming ?
I played games occasionally but the problems with the heating was even on the start up, the fan was spinig like mad all time with no application running, just windows. A friend of mine have this laptop and he got his vga card already replaced, we bought them at the same time. I also searched thru web and found many discussion about this laptpos cooling, and it really has this kind of problem.
I took the laptop apart and removed vga card, it is a separate piece, you do not have to change whole mainboard. That was also one of the reasons I bought this laptop.
I tried ebay but I am not willing to pay 250 USD for a vga card.

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.

A5200 has a bad Interface Board?

Sorry for the post about an old piece of kit.
I recently installed an A5200 with 22 FC drives and attached it to dual QLA2302 (I think) HBAs. All told everything works great, except port B0 on the A5200 will not show online.
The array is in split loop mode and the hope was to get 4Gb/s out of it through the four connections plus some redundancy.
The specs:
* Sun V40z
* OpenSolaris build 128a
* 2x QLA2302
* 4x 1Gb GBIC
* 22x 73GB ST373454FC
* 1x A5200
The A5200 shows B0 having zero nodes and the other three having 13 nodes.
I have tried the following and the problem stays with port B0:
* Swap fibre cables
* Swap GBICs
* Swap HBA ports
* Swap HBAs
* Reseat interface board
* Reseat GBIC
No matter what I do, port B0 will show a signal, but not online. Going into test -> debug -> 7 on the A5200, the "SOC HW Regs" screen, shows all working ports with an AL value of 0001, while port B0 cycles between 0080, 0800 and 0400.
The only thing I haven't swapped are the interface boards.
I have looked high and low in the documentation and cannot find the meaning of these "SOC HW Regs" values.
Do I have a bad interface board?
Any and all insight appreciated.
Sincerely,
Marty

I hate to reply to myself.
After reading the troubleshooting guide closer, I enabled auto-bypass and port B was disconnected from drive six on the front backplane.
A simple offline, remove, insert and online reset everything to it's regular state of happiness.
Now zpool is scrubbing a 22 disk RAIDZ3 stripe at 250 MB/s and I am much happier.
Hopefully this will help someone else save a little aggravation.

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).

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.

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!
Eric

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!

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

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

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.

Z77A-GD65 power issue/bad system board?

Looking for advice. I am afraid its a bad board, but some symptoms point at power which also makes no sense.
This is what the WHOLE system should look like.
MSI Z77A-GD65 system board
Intel 3770K 3.5Ghz
Anted Kuhler H20 620
G.Skills RipJaws 16GB 1600Mhz DDR3 F3-14900CL9Q-16GBXL (on the test list)
Asus nVidia GTX 680 video card
OCX Vertex 3 256MB SSD
Seagate 500GB data drive
Razer Lycosa Keyboard
Razer DeathAdder Mouse
Antec Sonata IV case with Neo ECO 620W power supply
It seems to me that 620W should be more than enough. According to my calculations thats roughly 330W of power draw against a 620W powersupply.
I am not currently over clocking.
So what the system does look like is:
If I connect the 500GB drive then windows starts rebooting as soon as the Windows logo comes up.
If I place all four sticks of RAM in the system windows starts rebooting as soon as the Windows logo comes up.
If I leave the 500GB standard sata drive off and only use 3 sticks of RAM... well we get a solid system and I am writing this message on it.
3 sticks of ram appear to work in any 3 slots and allow the system to boot, except 1,3,4. That combo also resulted in the reboots at the windows logo.
I first thought it was RAM, originally I was using Corsair Vengeance. I saw some posts here about people having the same problem, and noted that the Corsiar RAM was not tested and switch to a the tested G.Skill instead.
Any ideas? It does not completely seem like a System board issue, but it certainly should not be power. All heat levels are well within normal and as I said the system works great if I leave off the drive and one stick of RAM.
Thanks guys....

System torn down, and put back together. (Found out I was out of Thrermal Compound, so I had to run to the store to get some.)
No long leads, only 9 stand offs matching each mount point on the systemboard.
Back together... problem is the exact same.
However, back to the hard drive issue. I decided to play with that since I was getting no where with 4 sticks of RAM.
What I have discovered is that with NO sata cable connecting the drive to the system board, if I try to power the two 250GB standard sata drives the system reboots just as the Windows logo should come up.
The fact that this behavior is so close to the RAM behavior... I am back to thinking its a power issue, though system board is still a chance... its just easier to buy a new better power supply than the Antec Neo Power 620 that came with the case. (I have not ever had a problem with Antec before, and will likely just buy one of their higher end power supplies to replace it, but I think I will try it next, just in case.)
I am not seeing any strange behavior power wise as far as any monitor shows... but connecting power to a sata drive that is NOT connected with a sata cable and causing a reboot just screams power at me.
Anymore thoughts today. In the mean time off to play Secret World with just the SSD and two sticks of RAM, which still runs rock solid.

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.

G5 ALS Won't Boot Past Grey Screen...Bad Logic Board?

Hi all-
I did a quick search, and found various answers, but none specific to my situation, so below, please find my tale of woe, and I appreciate in advance any advice you folks could provide:
I have a G5, 2.0GHz, 20" iMac (upgraded to Leopard) that recently stopped booting past the grey screen/ chime. Somewhat irked, I did some trouble shooting to include the following:
1 - Reset SMU
2 - Zapped PRAM
3 - Run Apple Hardware Test (all tests passed)
4 - Repaired hard drive by booting to the install CD ... it returned errors that were not fixable, but since the log is on the computer that crashed, I don't have the errors to post here
5 - After that repair, the computer booted, so I ran disk utility again, repaired permissions successfully, verified the hard disk via S.M.A.R.T. (arguably, not the most reliable indicator of hard disk life).
6 - Just to be on the safe side, I did an Archive and Install.
All that done, I was able to use the computer for 2 days, and this morning, I woke up to find the fans a-blazin' and the computer non-responsive...I rebooted to...you guessed it!...a grey screen.
Luckily for me, my memory (akin to a steel trap!) served me well...I had the power supply changed two months ago under the repair extension program for my model iMac (bulging capacitors)..but they did NOT replace the logic board.
If you have made it this far, thank you for reading, I am building to my crescendo....
Being a slightly balding fellow, I have very little hair left to pull out here, so in desperation and with my recent power supply repair in mind, I pulled the back off of my beloved iMac (my very first Mac!) to reveal a bulging capacitor on the +logic board+.
My question: Could my symptoms be related to the logic board (remember the AHT passed), or might it be related to a bad hard drive (remember the S.M.A.R.T. status was verified)? Any troubleshooting steps I may have missed? I am going to bring it to my local Apple store, but wanted to know if there are any other ideas out there for me to try before making the 1.5+ hour trek south to a Mall.
Thank you all in advance for any advice you may have!
Best,
jason

Not only do you have a hardware problem, you should call Apple, tell them that you had the power supply replaced two months ago (you are within the 90 day warranty period), and ask that they replace the motherboard as well, since the previous repair didn't work.
