You have several bad capacitors in your TV. There are in the deflection side of the board. I think there are three here. And check the vertical section, as there are three bad caps. You will need an ESR meter to find and replace these capacitors. The older Zenith are known for shut down due to weak and bad caps. Hope this clues you into the fix. Thanks for asking and show a few hands of support!

Picture


I assumes that there is a confused memory IC inside, due to improper data inputs. Try a hard reset to this set. Unplug it from AC mains wall socket, and re-plug it back after 10 minutes of so. This must make it a hard reset. If it do not help you, contact any service technician.

Vizio vx42l Tv will come on no pic, after about 60 sec color lines fade onto the screen, tv will not turn off, need to unplug


It sounds like you have shorted CRT neck board, and it you probably would be better off buying a new LCD.

On/Off not lit when plugged in


There is help for this in the user manual. Possible solutions I would try:

1. Make sure your source sound (TV, amp etc) is up high enough - if the sound is too low the headphones won't detect a signal.

2. Try changing the channel (the switch on the bottom left of the cradle base) and pressing the "Tune" button on your headphones. Try all three positions, pressing "Tune" at least 3 times in each position.

3. Take out batteries & turn off base, leave for 30 secs, reassamble and try step 2 again.

Should all work ok. I've been using mine for over a year and they're great!

No pic or sound


The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.
