stuck on apple logo a2141 820-02037-a

[larrysito007]

was liquid damage and i did a ultra sound on the left side ( so if laptop normally on front of me as in the chassis)just the wing area and it started up but it is just stuck on apple logo and no progress bar

the washed side has no usb-c connector as it was burned but i will put there a new socket once this is working

the ssd-s are not shorted

there is no usb connection as did try external keyboard and others but nothing

the caps-lock is not working at all as light not coming on

there is the 1,8v for the keyboard i tested that (did try other working chassis)

i think something is holding the communication bus but not sure what next

please advice

thank you

First of all, welcome to the forum!

Try to start in boot menu.
Just to see if keyboard reacts on start-up.
You can also test, with machine turned off, if turns on pressing any key, or clicking trackpad.
If you detect any reaction, may be good to test it starting in safe mode also.

Sometime, T2 machines stuck on logo, or boot looping, can be recovered with DFU restore.
Be aware, restore will erase SSD.
