But needed later to reflow Ati graphic chip to fix display fail.

Hi Maxim !
Unfortunately lap stopped display the day after.
Wish to precise that , 1st time I fixed a new dumped bios to get display.
Few days after, display failed.
Heated ATI GRAPHIC CHIP and got again display.
The day after, no display.
Heated again ATI CHIP but didn't help.
Found pin 2 of Bios chip : +V3.1 ????, Tried to dump bios to no avail. Got error read message, so BIOS failed.
Changed a new dumped bios, no display, but got always pin 2 : +V3.1 ?,
it should be about +V1.6 I guess ??So couldn't conclude whether it's Ati fail, Bios chip or Bios supply issue ?
Please help !!!
