Distorted video disappears after warm
There must be a engineering flaw or a manufacturing defect on the PowerBooks. There are thousands of people who have this issue - look at the Apple support pages. When I first start up my PowerBook the video onscreen usually does a dance for me and after awhile, when the computer has warmed up it, goes away. Though sometimes it will come back full force after warm-up too. The issue is present when using an external monitor as well. So, it is the ATI Mobility Radeon 9600 graphics processor or VRAM.
I have read that Apple moved from lead based solder to tin for environmental reasons; the tin oxidizes and causes poor connections. I am not sure millions of customers tossing computers because of premature failure is any better than using solder with a bit of lead in it. I digress. So, is there a way to salvage the logic board? Re-whet the solder or remove the oxidization? Replace components on the board? I have taken the computer apart a few times to discern what causing this - the cable connections are fine; undamaged.
Is this a good question?
