Acer LA-B991P - Turns on, backlight, sometimes brief picture, turns off.

Hi Guys,

Trying my luck here with an Acer board someone dropped off. I don't even know where to begin with it.

It turns on (fan spins), backlight comes on, it sometimes (if it's been off for a long time) gives the bios splash screen, then it turns off. Won't turn on until I disconnect the power for a little while and then it repeats.

It has no liquid damage and looks really clean and tidy.


Any suggestions appreciated!

ive had this problem before, it was the gpu, have a look on laptop-schematics and see if you can get schematics for it, probably cant get a board view for it tho

As in a similar problem to the 820-2915?

Probably not worth spending too much time on it.

for me, I take a non refundable deposit to cover schematics and donor boards, therefore I only lose my time if it turns out not fixable
