Hi I need help for Acer JM50 Rev 2.1

Everything was OK, I just clean with alcohol bios chips because I see some liquid and after that laptop turns on automatically when I plug charger but no video

I try flashing bios chips
reflow graphics chip littel bit
reflow CPU littel bit

Same story

I have 3.3v and 5V in coils
I have 1.5V in Ram
1.1V in CPU
0.8V in GPU
19V in monitor display

Any help

Make a request for bios in "Bios Section" and post your old bios backup along with laptop model number.

Thank you from everyone,

Problem was when I clean board, first resistor was gone from motherboard and today I see that missing.
