Funny problem with TV - menus going crazy!
Hi All,
The guys at SED suggested I post here for some advice from the experts. I have a Zenith A25B33W TV that is doing funny things. The menus pop up, and start going through themselves at random. If I have the remote in my hand, I can cancel them, but then a few moments later, they pop up again. It doesn't seem the be the remotes, because I have removed the batteries, and the menus keep popping up. I have even covered the IR port on the TV, and that doesn't stop it. So, any suggestions? I had one suggestion that it might be a bad LV power supply causing flakey voltages on the logic board. I don't want to open it up, until I know what I am looking for. This set has given flawless performance for almost 10 years, so I hate to have to replace it. Thanks, Charlie |
