Hi everyone,
Acer Nitro motherboard FH52M LA-J891P Rev.. 1B
The laptop arrived with a short circuit on the main power supply line +19v
After measurements and a short circuit test it was discovered that PQZ2 (AON6962) and PQB11 was damaged. After removing it from the board, the short circuit on line disappeared.
once the components have been replaced the mainboard now starts but does not give any image on the screen.
the fans spin, the keyboard lights up but no image. if I put a USB stick with LED it doesn't flash. If I remove and insert the power supply I hear a beep. the battery has charged
I noticed that There is no voltage on PLG1 - +VCC_GT, the rest of the voltages on all coils are correct.
I tried swapping PUG1 with the other components on the board but the power doesn't come back +VCC_GT
any advice on what to try?
I haven't flashed the bios yet. It is possible that a corrupt bios does not activate +VCC_GT ?
