Hello, maybe here I can find help :D
(If I can fix it will be mine, I got it after about a month after flooding)
Laptop after flooding, I checked the motherboard and it looks clean. Only at the air outlets you can see liquid and the keyboard smells like coffee :D
100% screen and touchbar does not work
Laptop on battery alone does not boot from the button, you have to plug in the power adapter. When the power adapter unplugs it still works.
First boot with power supply plugged in - chime can be heard, keyboard lights up
Second startup - same as first startup
Third startup - Keyboard has no backlight, no chime, only the sound of plugging in the power adapter can be heard
Fourth startup - nothing, starts up (fans spin normally) runs with a few seconds (fans go into high speed) and the laptop shuts down
I disassembled the laptop and with the help of boardview (board 820-00850-A) I checked the voltages and if any components are shorted (I'm a beginner and don't know too much about checking motherboard components)
I checked all the fuses and they are OK
The only thing I noticed is L7430, L7420, L7410 are shorted, L7210 and L7220 are around 0.9 V
Could it be that the CPU is dead? As if anyone would like to help, please write which components to check with a meter at power on (Today I will no longer be able to check and respond to answers. Tomorrow around 10-11 PM GMT+1, I will be able to check it)
