Issues with Zenith Z50PX2D I heard a loud click ,like a relay ( maybe the so called pop of death) screen went pixelated for a few minutes then went out totally. I have removed back cover. When I turn it on i have 3 led lights lit up for about 15 sec. then a relay tick on the board in the middle top. Would assume P.S. board with all the transformers. after the tick, no leds and no life. I have to let it sit unplugged for 10 minutes or so to be able to repat this process. Any ideas on what to troubleshoot or maybe what this may be, as in common board for this problem. Thanks in advance for any advise.
