Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

TV powers up for literally a second then shuts down (PT-47WX49)

The TV starts to power up, but then I hear a click and it shuts off. I have to unplug the power source and plug it again to have it repeat the issue.

    On a PT-47WX79E, Chassis DP820, I have the same problem. I checked R517 and it is still good. Would appreciate any other suggestions.

    after a covergence amp replace, replaced with stk-150's and replaced the 6, 2.2ohm 5 watt resistors, turned it on and had picture for like 90 seconds. Picture seemed to jump a bit horizontaly. When to do the convergene lined green up , then went to red, as i lined red up, TV powered off. no led blinks at all. I then have to unplug it then plug it back in, powers up for bout 5-7 seconds, and right as the picture would normally kick on, it kicks off completely instead. problem is repeatable , havent had picture since the first time powering it on after the repairs. no led blinks at all just stays solid till it has the shutdown.
