There's a few things that can cause this- most common are the power supply and Mainboard. A telltale sign the mainboard is likely, is when you can't shut off the TV without unplugging it. However if you want to narrow down the cause further, you'll need to use your meter.

Remove the back of the TV (if it is not already), then ground your black meter probe to chassis ground, press power, then use your red meter probe to check all of the plug in connectors on the power board. Next to the plugs voltages are stamped on the board. Let me know what you get for voltages and we can proceed.
