A friend asked me to look at their Toshiba Satellite L500D. The machine would show all its lights as if booting normally, hard drive would spin up and CDRom would also initialise. However although all the lights were on there was nobody home and the laptop showed a black screen. I did the following:
1. hooked up external monitor - no change
2. changed Ram - no effect
3. changed processor - no change
4. disconnected all peripheral devices, speakers, usb's etc - no change
5. Reflowed northbridge with heat gun (it's all I've got) and laptop booted up fine.
I see a lot of people on Google have this problem so i thought I would share my experience. Some suggested a Southbridge reflow but that doesn't have much to do with graphics.
Since this is not the dreaded Nvidia chip that has manufacturing defects (8600M) and reflows are temporary with those chips will a heat gun reflow be enough in this instance?
