Aspire A315-56 LA-J801P shutdown after 4 seconds

[johnbeton]

Hello,

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

First we need to know which areas were exposed exactly. Any pictures taken before you started with the work?

i'm sorry, I did not take pictures before the work. It was the area around PU501 and on the other side of the board on the keyboard connector. (to test I unplugged the keyboard and short the pins to start)

Then it is the time to show pictures of the actual situation at least to start the troubleshooting from the area of the SY8288CRAC
