and the blue power button and red status light start flashing quickly.
The sound is not affected, so I assume that everything is still working, except the lamp.
I unplug/re-plug the TV and the lamp comes back on and stays on for a whole movie.
This doesn't happen every
time I watch a movie; maybe every third time.
Does anyone know what causes this behavior? Could I have done something while dusting the inside of the TV to cause it?
I was very careful not to disturb anything while dusting, and other than this, the TV works great and the picture looks perfect.
If it matters, I only watch movies on the JVC, so it's typically on for about 2 hours, then off for 4 or 5 days.
Thanks for your help!
Hrmm... I had a problem where the TV would require several attempts to turn on. You could hear it buzzing and trying to spark a connection, but it would fail and the lights would start blinking like you described. But I've never had a problem where the TV has been on, and then randomly shut down on me...
But for the hell of it, try removing your lamp and using compresses air or a duster inside that area. Once I tried that, I never had my problem again (a lot of dust for such a small area dissipated when I used compressed air).
Or, maybe while dusting, you knocked some dirt loose and it got into the LE or main board, or whatever... and it's now overheating.
For example... my desktop computer recently had a problem where it was shutting down randomly on me. So I took it outside and got all the dust out of there, specifically the dust on the CPU fan. Apparently, the computer was overheating because there was so much dust (probably thick enough to keep the fan from even working, as the computer had been stored in my garage for a year before I had started using it again). Maybe your TV is suffering a similar problem with overheating.
