Hello Ivolvo, This problem denotes a problem with your color section of your TV. First I need to know if you have a background in electronics because if you do not it will be very difficult for you to understand what I am talking about. First you will need a schematic diagram of your TV. Then you wil need a multimeter to measure voltage and resistance. Then you will need an oscilloscope, finally a sisgnal generator (use color bars, or gated rainbow). These pieces of equipment will allow you to troubleshoot your problem. If you do not have a background in electronics, please take you set to an electronics shop for repair.

Zenith R45W46F has sound but no picture


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Colors going bad on my tv?


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.

I have a 26inch Console Zenith Color TV, when I turn it on, I get a full pidture and sound but after 30 seconds, about 6-10 inches of the bottom screen goes black--but the rest is ok???


Hi,

Get the remote control and press the MENU key repeatedly until you see the Video menu at the bottom of the list of options you will see EZ Picture.
Use the up/down arrow keys to select EZ Picture and use the left/right arrow keys to select your preference. Set the preference to Preset not custom.
Press Enter, Quit or Menu to exit. See if resetting the TV's Picture settings resolves the problem.

If you have a bar at the top of the screen as well then it could be in letterbox viewing mode. Again just go into the Video menu and turn it off.

Please let me know how you get on.

Good luck.

Can someone take a picture of the original video settings on their Zenith B25A24Z 25'' TV because my screen is all messed up and doesnt get much better when i play with settings.


If this TV is a 25"...then this is an older set. Is the picture dim and the colors dim, will the tint not correct the color scheme? Zenith picture tubes, as a rule, for this model go bad...sorry but this is true!

Tube set zenith tv


This is very typical of a Zenith set.Your picture tube will have to be replaced.One of your 3 primary colors (red,green,&blue) have turned off leaving you with the color of the dominant color.I would heave it.

Screen full of moving colored lines


I would suspect bad solder connections allowing a ground to "float" It is a common problem with the model P42W24BX which I believe uses similar circuitry as your model. An experienced repair shop should be able to get you fixed up.

Zenith 25in. System 3 TV. Intermittent problem with color going all red??


It certainly sounds like a drive problem in the set. It could be a bad connection on the CRT socket, a componet on the CRT driver board, a bad drive transistor, a connection between the CRT driver board and the RGB /video jungle IC, or the RGB/video jungle IC itself. If you know how to solder and or have some sort of solid state repair experience, you should be able to find this problem by simply probing around with a wooden or plastic tool tilll the problem arises. If you have no experience, there is no easy quick fix. You should find a local repair person to assist you with this repair. good luck PS Please dont forget to rate this thread.
