HITACHI 50EX11BV PROBLEM

[LUGOCNC]

My hitachi 50ex11bv TV has no power will not come on. It started out it would come on then cut off after a few seconds. I could do this a few times then would stay on. Now will not do amything. Does anyone have any ideas. I am a service tech for cnc machine tools but have no information for my TV. PLEASE HELP.

I was able to get power to the TV and when I turn the TV on it clicks and cuts off. If I do this for about 10 min. The TV comes on and works great. There is a Relay that clicks does anyone have any ideas I think its the relay but not having any drawings ws wondering if there is something else causing it to drop out.

Thanks for any help anyone can give me.
