I wonder what I could damage. I used tutorial from yt.

Console works, games are running without problems, it is silent after new thermal paste.

But blue ray is dead: - not responding when pressing bottom eject button. - not reading already inside cd. - not accepting any cd - no option to eject from controler options

I wonder what could go wrong. Some cable? Something wrong with this small board that is next to blue ray?

I see small board, 1 4-pin connector, 4 tapes( 1 from motherboard, 3 from blue ray). Everything connected but not working.

Anyone has some clue how I can fix this or investigate?
