The graphics on my old MacBook Pro 17" A1229 have gone all wishy washy. I have been told this could be the Graphics Motherboard or the Main Logic card. What do you think? How much would it cost to replace either of these?
To diagnose the GPU (graphic processing unit) hook it up to an external monitor. If you get the same wishy washy picture, it is the GPU. If the picture is good, you have issues relating to the display. UPDATE http://www.everymac.com/systems/apple/ma… Unfortunately this model has the GeForce nVidia 8600 GT graphics processor. There were class action law suits, resulting in Apple repair programs to replace those GPU. These programs have long since expired. There are services that can be found on eBay that replace these defective processors. This is a much better alternative to replacing the logic board as you will probably get a board with an un-replaced GPU and be faced with the same problem. You’ll need to compare the cost of this repair (usually about $180) the last time I looked, with what the machine is now worth. This replacement repair is only $115, it may be because few of these are done anymore and they may be just trying to get rid of surplus chips in stock: http://www.ebay.com/itm/Apple-Macbook-Pr… http://www.ebay.com/itm/MACBOOK-PRO-A126… http://www.ebay.com/itm/MacBook-Pro-17-A…
