Answer to: My screen fades/distorts, but an external monitor works fine.Jeff - That video would be a lot funnier if I hadn't paid so much for my laptop! It is nice to know there's another technique besides waiting for it to heat up on its own. Thanks for the Youtube URL. I wonder what's going on with these MBP's? For my second logic board replacement the Apple store sent my laptop to some repair depot and they replaced the logic board, a video cable of some sort and one of the memory chips. According to the Apple store manager this depot place was the ultimate level of the Apple repair process. They supposedly check out everything and replace anything that is remotely suspicious. Yet a few months later the problem comes back. I'm on my 8th Apple computer and this is the only one (and the most expensive) I've ever had a problem with. Thanks again, Ken
Answer to: My screen fades/distorts, but an external monitor works fine.I have the same laptop (A1226) and have had the mother board replaced twice by Apple under the extended Nvidia warranty. A few months after the last replacement I began to experience the same symptoms you describe and still have good video via an external monitor. I found after leaving my laptop all day the video came back. It seems to work once it's been on a while and has a chance to heat up. One weekend I ran video DVD's all day and left it plugged with all the energy saving options turned off for a couple more days. It works ok now, mostly. I still have the video issue off and on but leaving it on for a while seems to bring it back. Clearly something else is going on with this model beyond the bad Nvidia video chip.
