HOW DO I FIX MY ZENITH TV HAS NO IMAGE

Sounds possibly like image retention. If you watch the same channels often any recurring text, logos, or graphics, especially white colored, can ghost on the screen.(playing the same videogame for a long period can also have the same effect) Watching other programs or channels will cause the ghosting to disappear.

To prevent image retention you need to activate the TVs anti image retention mode(Called ISM Method). On Zenith and LG (the manufacturer of Zenith T
s) plasma TVs open the TVs menu, select the Option section (picture of a briefcase with a wrench). Select ISM Method and change it to Orbiter, this is reccomended if you watch programs or channels (or play videogames) that have still images for long periods of time. It moves the image a little every couple minutes.

If watching others channels or programs doesn't make the image disappear, change the ISM Method to either Color Wash or White Wash (don't use White Wash frequently, it over excites the plasma gas and can shorten the life of your TV if overused) for a few minutes and then return to Orbiter.

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!

Well - Good news - This is a convergence issue. Some how the Red's CRT's image has drifted off of where it should be of overlaying itself on top of the green and blue 'which make yellow by the way'.
If you contact a Zenith/LG Service center they may have a TV Tech that can come out and fix this issue. May be between $100 to $200 charge. Just guessing but this is fixable.

Ur convergence is dead,need convergence kit.
U know how to solder right?Tries these websites for convergence kit.Tv Repair World.com,Shopjimmy.com,Ebay.com or Partstore.com

This needs a special remote to get to the factory alignment screen.This is the part # for the remote ---#105-201m .
You really should call a good TV Tech on this one. They are a convergence nightmare for even a good Tech.

it requires a TV repair person to fix the internal problems.

Multiple image is usually a result of transmission problem. The signal from your local station gets transmitted two ways, by tower and cable. If the tv receives them both at seperate times it will create an overlap or shadow effect. I would try a small power booster on it, if not a service man may have to adjust the internal circuits.

call zenith for repair
