Why you suspect your video chip !..did you make the basic test before , make sure your problem NOT on LVDS cable or LED panel , is there a picture on external monitor !

whn you say that you reflash bios ,did you clean it !

Did you take the voltage measurements on lvds connector !

when i heat the avga1 chip, the picture will come up normally for 1 or 2 days

It is possible and tested already, check the internet I saw solution on russian forums, or use schematics

Which chip is that exactly?

But generally yes, chip responding to heating = replace.
