Question about RCA F32450 32" TV
I have a 32" Zenith A32B43W set. When Power is pressed either on the remote or on the set itself, the relay clicks on then off immediately. This happens most of the time with the set never coming on. Every once in a while the relay stays on and the set works fine. We think this happened during a lightning storm... Is it a relay problem or something bigger?
The relay is part of the overcurrent circuit. This denotes a problem in the HV power supply. Try to resolder the relay just in case the it has a cold solder joint. If this does not help get a schematic and a multimeter and check to see if the voltages around the power supply seciton of in order. If you do not have a background in electronics please take the set to a TV repair shop.

Classic symptoms! Most of the last TV's made by the old, original Zenith company (Rauland division) had bad picture tubes even when new. This probably had something to do with their going out of business and being taken over by a much better Korean company (LG Electronics AKA Goldstar). Another lovely thing they did before biting the big one was to only sell a complete chassis as a repair part. If your TV is older and has a small white paper tag inside somewhere on the picture tube (usually near the larger brand and type number label) with the code "EIA 1101" on it, discard it. I have NEVER seen one of these work correctly! If the CRT is made by someone else, there may be slight hope. Even if the TV is not very old, if it was really made by Zenith, and not LG, the possibility of repair is slim simply because of the change of ownership. I was sad to see Zenith die such a horrible death. They used to be fairly good, but somehow never made the transition to color TV. After 1954 they were essentially moribund.
