So in a bit of a cruel coincidence, just as I was deciding on a new TV, my old one started having problems. It's a 2005 Panasonic CT-34WX54. It occasionally cuts off and won't turn back on. Sometimes when I unplug it and try again it works, and other times it doesn't. When I try to turn it back on, it gives me its usual set of lights and clicks, and then right when I expect to see the screen start to light up, it dies.
Short of shutting down completely, it sometimes flickers and/or goes black but remains powered on, and then a few seconds later the correct picture returns. And often the mute or volume controls don't work properly. The MUTE sign comes onto the screen, but the volume doesn't actually mute. Or if I change the volume, the volume numbers change on the screen but the actual volume on the TV doesn't audibly change. Sometimes the volume change will kick in a few minutes later, well after I've set down the remote, which has fresh batteries. These problems may sometimes precede the unexpected shut-down, but I don't have a large enough sample size to say for sure.
All of this is intermittent. The TV usually works fine for a while before experiencing these problems.
My dilemma now is that I'd like to keep this TV in working order, if it makes sense to do so. I've been very happy with its picture and performance. When the new TV (Panasonic TC-P55ST30) arrives, my plan was to put the CRT in our basement game room, to replace the 1993 JVC 20" set we have down there.
Any idea of what's wrong with this TV? Is it worth taking to a repair shop to see if they can fix it reasonably? Any chance of a DIY repair (I'm reasonably handy with tools and can follow instructions but have essentially zero knowledge of TV innards)?
Or should I just cut my losses and buy a new one for the basement, too?
(I did a search and didn't see anyone with similar problems with this or related models, but if I missed something please feel free to direct me to it.)
