If there is no video output to an external monitor, changing ribbons won't help, the fault is before it gets that far, as others have said, on the grpahics chip, which is usually built into the motherboard. Testing a laptop motherboard isn't so easy as a desktop one, not least because it is like heart surgery taking it all apart, compared to a 5 minute job removing a desktop one.

If the GPU is kaput you could send it to somebody like this to have them reball it for you: http://cgi.ebay.co.uk/Sony-Playstation- ... 3784wt_672
Lead-free solder is the main cause of all these GPU problems!

Re: Need to pick another geek's brain here
npm: reballing doesnt cure the issue, merely delays its reonset sadly, sometimes it doesn't even work, problem is a lot of the time that the GPU itself is totally and utterly fried due to the poor heat dissapation due to the bad design of the cooling system.
