Zenith tv no pic

Connect the input device to some other TV and check. Look for: child lock, selective mute button, basic TV volume too low etc.

cheaper to just buy a new tv mate,sounds like the pixels for that half of the screen are gone.

While watching, TV made a sharp bang sound. Sound Problem with the Zenith Z50PX2D 50 in. HDTV Plasma Television While watching, TV made a sharp bang sound. Sound still good, channels can be changed, but no screen, now tv wont come on at all?

The picture tubes in Zenith sets (I assume it's a Zenith since you posted this with a Zenith heading, although it's also true for any set this old) were only expected to last around 7 years. Your description makes it sound like you are missing green, or that the green is just way low. This is a common sign of a bad picture tube. There are other possible causes, but tube failure is the most likely. The low replacement cost for small TV sets makes repairing this one uneconomical.

Get rid of the set and treat yourself to a new one.

Sounds like a CRT is arching internally. to confirm remove the covers to have a view of the picture tube necks- in adimly lit room you should see bue arching in one of the tubes. (there are three piture tube with glass necks)

I do not have a Zenith B25A02Z TV. What I do have is a 1988 Zenith Color TV SE2517P. I called a local tv repairman and discussed the problem over the phone. He can take a look at it if we bring it in (service call to the home cost $100 just to show up). He said it was worth fixing since he thought it was only the sound. We have a great picture. He charges $20 to look at it but we have to leave it. He lives 20 minutes away one way. We think it is worth the trip if we can get it loaded into our minivan. We live in western NY where the weather can get pretty ugly many days. I will post the solution later when I know. FYI

There is a coil in the set with a magnet glued to it, called the horizontal linearity coil. Sometimes the coil "sings", making a squeeling sound. I have seen this many times, and there really isnt anything actually electrically wrong with the set. To stop the squeeling the coil should be replaced.

you have the famous zenith shorted picture tube
