SOLVED: A2485 No picture internal or over HDMI

[it-solve]

First time working on 16" 2022 model

Might be overlooking something. Suspecting an LCD issue, but to be sure I have disconnected all 3 connectors to the LCD and tried over HDMI. Still no picture.
Can hear its chiming as well as capslock response.

Unfortunately cannot test with known assembly as I don't have one. Only have 2442 model which is 14" and seems not compatible.

I can see the capslock light comes on and off and can hear the chime.
The customer mentioned he saw a faint screen (no backlight). I can't see anything. but sometimes if it was restarted too many times unproperly it falls in a recovery/pre-os loaded state. Is there a way how I can skip the Recovery or other part pre-os loading?

Try DFU; revive, if still want to recover data.

End up being a faulty screen. It's so annoying that we cannot even test them over HDMi anymore easily.
