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

Re: A32B43W Power Problem
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.

What kind of television are you trying to program the Zenith Remote to? If it is a Zenith TV, it should work after replacing the batteries. If not, the remote returns to the factory default to the Zenith Code. If you changed the batteries cuz the unit would not function, the remote itself may be defective. Replacements are still available at a ZENITH dealer at a nominal cost.
It's a Zenith remote, MBR 3440 is the model #, 124-202-01 is the part #. To program, press and hold PRG button until red light stays on, press TV,AUX etc, enter 3 digit code (www.xdiv.com) press Enter.
No, you cannot disconnect the power switch. A defective power switch will not make the set turn on and off by itself, because the power relay is actually controlled by the microprocessor. The microprocessor in your set is trying to start the set but immediately detects a fault somewhere and shuts the set back off. This can be a difficult problem to solve and the set should be serviced by a qualified tech.
First of all, forget about the remote and see if the TV functions normally using the buttons on the front of the set itself. If the TV will not power on with the power button on the set itself, then something is wrong inside the TV. If the set works fine from the front buttons but no longer responds to that remote, then the remote has either gone bad or was accidently set to a different brand. In this case, look for the original book that came with the remote (or TV if it is the original remote) and follow the instructions for setting the remote back to Zenith. Try that and post your results here.
