4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.
Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.

Motherboard model: FDI55 LA-J081P
Today a customer delivered this laptop completely dead, with the original power supply shorting when plugged into the connector.
I found and replaced a shorted MOSFET (PQZ3).
Now the laptop turns on (fan runs fine but no video signal) and after 5 seconds it turns off.
BIOS has already been updated (both 64MB and 128MB IC)
+3VALW and +5VALW are still present.
+VCCIN = 1.8V stable (measured on PLZ1 at power up)
Abnormal readings:
PLZ1 to GND = 0 Ohm
PLZ2 to GND = 0 Ohm

by Pygo86Hey Folks,
i'm not far into Monitor troubleshooting. It's my first time. Normaly i try to repair Laptops.
The Monitor is powering up. And the Backlight turns on. After a few Seconds the Backlight shuts off and the Power LED turns form Blue to Red.
I can power it up again, but it's always the same Result.
No Matter which Connection is used.
I can't see anything obvius after disassembling. No Heatspots with the Thermalcam visible.
The Powerboard is looking great. There is 12V and 5V everywhere on the Logicboard.
So, i decided to swap that Logicboard....3 Photos-

by johnbetonHello,
I have a Aspire A315-56 with a LA-J801P mainboard.
After liquid damage, the system did not power on at all. After replacing PR509 (499K Ohm - ENLDO_5V) the powerled goes on for 4 seconds, then shutsoff. No image.
Anyone an idea what to check next ?
Thanks in advance -

Before turning off fan also turns on.
