Question about LG RU-42PX11 42 in. EDTV-Ready Plasma Television
Hi everyone. I have an LG 50PC3D plasma and its not turning on. I plug it in and when I turn it on it makes a click noise and then another click noise and turns off. Any help??
Without seeing the unit itself and opening it up/running tests I couldn't tell you exactly what is happening, however I can offer some suggestions as to what it could be.
1) your power supply is bad. That clicking sound is the power relay coming on and going off.
2) your main board is bad. It handles a lot of your signals for powering on your set. If it's bad, the tv won't turn on correctly as it doesn't recieve all the right signals.
3) your Y or Z boards are bad. These could cause the power supply to go into shutdown if the voltages on these things are too far out of whack.
Easiest way to tell if you're going to go into your tv is to try to unplug your Y and Z boards and turn it on. If it turns on and stays on chances are one of those two boards are bad.
