Hello

I'm trying to repair a dead LG 32LS570S LCD screen. The backlight work
OK, all the power supply voltages are nominal and the unit turns on and
off via the remote or the keypad, but there is no image. The service
manual says "change the main board", but first I want to ask here if
this is a known fault.

Thank you

You didn't say if you have sound and channel change etc.
Service manual's here if it helps.
