My LG 60PA6500 would turn on automatically when plugging it in. The screen would be backlit but nothing was visible, no menu and you couldnt turn off the tv. I was testing the voltages on the X board I think when I shorted it out. Now nothing happens and all I read is 120Vac at the main board connection.

So they took the TV (a 60' which is not easy to handle) to the lab and asked me to check it.

Hello everybody,
I got HP ProBook 455 G7 which originally turned on partially(fans on 100%) and hen off after 8 seconds, with AC diode flashing orange and last flash white. This behaviour stayed for a while, but before I realised that there is power delivery issue and not BIOS problem, laptop started to automatically turn on after 2 seconds when in turned off, kept power cycling. So after I fixed shorted cap and burned ferrite bead, laptop turned on fine and booted to windows.
Now, laptop can be turned off and it stays like that... unless you plug adapter again, which triggers... -

what I have done:
cleaned the ME of the BIOS firmware, changed the thermal paste, removed all peripheral devices- (keyboard,...
