No color / Zenith TV Model SJ2771W

This tv set has absolutely no color at all. The picture is clear and sound is good. The color on screen display shows the color to be at maximum. I have looked for loose connections underneath the tuner IF board but havent found any. Im having trouble locating a schematic for this set.

You need to replace the color crystal (frquency is 3.579545 mhz) problem is I do not know which one it is... sorry. If you have the schematics for the TV it should be easy to locate but... you don't. See if the crystals in your TV are marked with a frequency. If not, try replacing one at a time... if the problem goes away your all set, if it does not or gets worse put the old crystal back and try it in the next. Do this at your own risk and watch out for that large red wire going to the picture tube!! Even when the TV is unplugged it can kill you!

When I turn my TV on, I have sound but only a horizontal white/color line across the screen. My TV is an old Zenith 25" floor model.


You can buy a new one for less than 200 bucks. I'd advise you do this. It sounds like you need a new

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

I have a 1994 zenith big screen the picture is showing really dar


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.

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!

16 yr old 25" Zenith..1st colors went yellow/lime now TV is dead


Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.
