My Panasonic CT-32HX42 TV (manufactured Dec 02) has a strange problem,
I wonder if it's a firmware glitch or a real known problem? For some reason, when the TV is in VIDEO 1, power is first turned on, and then TV/VIDEO on the remote is pressed twice in rapid succession, the degauss coil will activate, a relay will click, and the power LED will shut off. The TV then no longer responds to the remote or front panel buttons. It's completely dead until I unplug and replug its power cord. It's very strange. My wife can reproduce it... I guess my timing is off, because I have never been able to reproduce it. My wife can't reproduce it if the TV was left in tuner mode, and sometimes it doesn't do it. I've told her to wait till AFTER the first relay click before pressing the TV/VIDEO button and it's been fine. This TV weighs 135 lbs and is wedged in an entertainment center, so it's not worth even having it looked at under warranty if it only does it under that specific condition. I'm just curious if it's a known problem, and if so, what's the fix? Shawn |
