LG flatron monitor with touch sensor power switch... won't turn on.
Power supply puts out 5VDC OK.

but the LED status doesn't change when you push the button?
Probably there's a trickle power supply and a bigger power supply
that runs backlights and MCU, and anything that inhibits the bigger
power supply looks like 'dead ON/OFF switch'.

Shorted rectifiers and burst capacitors, maybe fuses, are the first things
to hunt for. Low-current finger-sensing gizmo is probably an innocent bystander.

I agree the 5vdc is some sort of standby. But THERE IS NO BUTTON to push, the sensing gizmo is the only thing to tell the monitor anything powerwise other than (un)plugging the AC cord. And the gizmo is in sorry shape by now.

Have you tried turning it on with the remote (if it has one)?
