Re: Nvidia Shield TV 2017 Dead

I removed U504, U505 and U506 which cleared the shorts around the last two but still a low ohm short in the area of U504 and now the MAX77620a is heating quickly and the board is drawing 270ma when plugged in.

Any suggestions ?

Hi, i've got a similar problem with a 2017 shield tv. it's not turning on at all, no green light. i've tested the power supply and the board is receiving 19v on the mains input so i assume the plug is working fine.
Also there is a very faint humming sound coming from the board when it's plugged in.

Is there anyone who has managed to diagnose and fix a similar problem with this model that would be able to give me an idea of where to go next?.

This is my first time posting on a forum so apologies if i've not done it correctly.
