bought this 47" lcd yesterday for $30 with the information that the set had to be turned on and off 2 or 3 times to get working which seemed to lean towards a flaky power button. Had nothing to do b with that as the same happened with the remote. Some times it would take a bit to get it to light up. Had it running for 30 minutes while updating my ps3 and the screen went black. Sound only. After that. Re powering would only quick flash and back off with still only audio. Tried again late last night and there was a rapid relay click a few times and a light hiss and now no power. Going to remove the power board today for some testing. What could I expect from this. Easy fix?
