Question about Hitachi 42EDT41 42 in. HD-Ready Plasma Television
I have an 42EDT41A with great sound but no picture. I took the back cover off and I noticed that the Main Control Board in the bottom of the 42EDT41A had an LED that constantly blinked to indicate a problem. Since I don't have the service manual for the 42EDT41A. I was wondering if you guys could help me diagnose the possible cause. I do know from researching your site that the 42EDT41A has a PCB problem, but no one has yet to state which PCB it could be.
OK I fixed mine. I took out the new bulb, and on the back side, there is a little tab on the right side of the lamp that should depress the safety switch. I think that once you take out the original bulb, the switch lever is weak and once you replace the lamp, the new one cannot depress the switch far enough. I built up under the tab (with some plastic from a pen pocket clip and some super glue)(after I took off the back of the tv to see what was going on) and it depressed the switch farther. I put it back together, and now it works. Saved a few hundred bucks. Good luck...
