Hi @nathandawson , i've had exactly the same problem as you. I accidentally plugged in a 19V/4.7A power supply into my Sony ps-lx310bt and since then no power anywhere.[br]
[br]
Couldn't find any power on the board using a multimeter, so I tried unsoldering the Zener Diode ZD001 from the board and hey presto the bluetooth light comes on. I havn't tried anything else until i've sourced a replacement.[br]
[br]
I'm wondering if you could help me identify the replacement zener diode? Do you happen to remember which one and where you bought it from? I really don't know what i'm looking for. Tried to google the number written on the diode but can't find any references.

I am really suprised that in 2023, and from a brand like Sony it's possible to do this with such an easy mistake.
