LG 22LE3300 completely dead

[Andreasbest]

Hello.
I got the 22LE3300 from LG tomorrow and it's completely dead, the problem is not on the external PSU as i test it and tried with bench PSU too.
Nothing seems burned on the board.
Please advise

Thank you in advance!

So, that TV is dead as a door nail. Much more testing has to be done in order to figure out what is going on here. You have to find out if:
-STBY voltage is present on the PSU and getting to the main board.
-PSon and BLon coming from the main board is present on the PSU after you turn on the TV
-or maybe the TV is on and the backlights are off.

This being said, if your PSU has been tested by forcing it on, I'd say you have a main board problem.

If you have not any PSon or BLon sending from the main board to the PSU, the main IC on the main board is bad.

This tv uses a seperate 24volt power supply (brick), (page 24) Looks like power comes in as VGH (+25v), check R627 (0Ω) Check VDD_LCM (+16v)

This is a Main Bd. problem then? If it is possible, a re-cap may start up the TV.
