Built in and also external display show no image.

Hey guys!

I have a problem that started in middle of May with regular system update on my Macbook Pro (15-inch Early 2008). After update the screen would not turn on even plunging in the external monitor didn't help. Macbook started normally as I have heard all the programs turning on even iTunes played music. I have tried almost all of the short-codes while starting the computer with no success. Tried with firmware restore CD - but it just got ejected. Luckily I remembered that team-viewer was installed on in and when I connected from remote computer I have seen that graphic card is missing (images in the links).

Does anybody have an idea how to fix this problem?

Marsovc - Sorry to tell you you have a classic case of NVIDIA GPU failure.

Here's a thread that goes into great detail of all details MBP A1226 Logic Board last resort fix for nVidia video chip. In your case it appears the GPU is fried and you'll likely need a new one.

Apple last may stopped servicing these systems or supplying parts so you'll need to go the internet to find a used logic board or if you have the skills getting a replacement GPU and replacing your dead unit.

While some folks have had some success using their oven or even a blanket to cause the system to over heat to the point the cold solder joint on the chip reconnects it is often doesn't hold up very long as the solder has broken down to the point it will fail again. But they had still working GPU's in your case the chip is just dead.

Sorry for the bad news ;-{

Thank you for your quick reply and for the link!

But I need to know just one more thing (before trying the oven method:) - how do you know that the GPU is fried? Did other users see their graphic card in hardware status?

I don't recommend the oven trick. The proper way is re-ball the chip and re-solder (thats if the chip was still good). In your case the chip is completely dead. How do I know this? The chip has a quite a few power lines going to it. It would be almost impossible for all of the them to be disconnected. As long one path remained you should have gotten a different response the GPU would be show in the hardware list.

I Agree with Mayer here, follow Mayers' link below.

Thank you for your help but today (after 5 months) it suddenly started to work. I know that it will die again and when it does it goes straight to the guy in "mayer-s" ebay link.

There are several companies of eBay offering work station GPU repairs for the nVidia 8600 issue. I do not recommend the oven method. Here's one: http://www.ebay.com/itm/330820993483?ssP...

Thank you and as I said to Dan - as soon as it dies again it goes for repair.
