Question about LG 42PX3DCV 42 in. Plasma EDTV
Thanks for using FixYa.These kind of issues in plasma usually happens due to bad cap on any of the boards inside. However, to check what has gone bad you’ll have to open the back of the unit you’ll need to check bulged/swollen capacitors on power supply board. As the unit won’t show anything for a long time so it means that it is the power board which is causing this issue. These issues usually happens due to overheating in plasma TVs after sometime, as these sets are very hard working device and produces a lot of heat. Please do accept the solution if the issue is resolved or post a comment for further assistance.

Either there is a bad relay, or a bad power supply. The relay if there is one on this model, would be on the power board. Trace the wires from plug-in cord to power board. Test the power with a voltmeter. There should be a label on teh tv set that states the DC Voltage Output. The number should match.
