Zenith tv picture is larger than screen - Zenith H32G48S TV

under options/menu on the tv you must chang youur aspect ratiao/ zoom ratio.

Unplug the cable box for an hour,replug it back in.Should get the cable box to reboot to updated the softwares.Might work than,tv seem to have picture,somethings on the screen,words mean ur tv still works.

The red gun in the picture tube itself is shorted on. You will have to replace the picture tube itself to fix the problem. Probably want to just buy a new set. Sorry!

Adjust the Aspect ratio. The manual will tell you how.

It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

The issue your having is aspect ratio. Some programs and commercials are broadcasting in a higher resolution so some fill the screen and some have black bars top and bottom. I suggest searching "aspect ratio for video". It would take me all night to type it out. But you need to know how the different resolutions change the size of your image. Also in the TV's menu you should see an aspect ratio option. Try the different settings to see if you can find the best.

Components in Power supply are bad most likely a 35v 100ufd capacitor if not then your Flyback transformer is bad

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.

My picture is a double image and has a sideways hourglass on the screen. Please help me!

The PIP module is bad or the video processor circuit. Most likely a main board replacement will be neccasary. Good Luck
