[gcomputers]

Hi i m working with this sateelite 6050A2177801-mb-a02 PT10A+/10AG+
start normally but no screen , i did reflow of 2 chip , nut no screen, flashed bios with original got it from official website ,NO VIDEO .

Don't have Nectokin.

I have seen on Winbond I/O chip , a small sign of burning of a pin , replaced it but no change.

Another thing the fan of the cooler is blocked, it does not work, maybe this caused a gpu or igp problem?????????
