My zenith television has black n white but should be color

old if it has a manual tuner there will be a fine tune adjustment.
It would be behind the channel selector knob or in some cases
very close. If the tv loses color try this first.
re-post if you need more info.

Zenith TV has me seeing red.

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!

Zenith Model SY2551S 1996 27" - Green Tint

The core problem with the green tint is the aging of the picture tube, and can be compensated a bit by using either the green drive control usually located on a printed circuit board on the neck of the picture tube or on the main chassis. There will be 3 main controls which will adjust the red and blue as well. If these controls are not present then you will need to get into the service menu and adjust it from there. Don't adjust anything else as you can make the set much worse. Also remember that in order to make these internal adjustments while watching a black and white picture (turn the color all the way down) you will have your hands and arms near live circuits that could shock you and cause injury to yourself as well as break parts inside the set when you pull back after being zapped (voice of experience here) Of course if you can do all this by the service menu then you won't even have to remove the back of the TV.

Zenith TV- greenish color

If you take off the back of the TV there are additional tuning buttons. One is for the focus. I have a model SY2551S and have the green tint problem. Have you resolved that?

Green tint I can't seem to fix

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.

By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

Green tint on screen

Is it a green tint at some areas alone, oris the entire image having a green tint? If it is a color patch at the corner or other areas of the screen, in all likelihood it is a degaussing problem. Color patches happen when the TV is moved from one location to another, or if some magnetic source is placed close to a CTV. Did you put a radio or Tape recorder or Walkie talkie toy or any magnetic source near the TV? if yes, remove it. And the automatic Dregaussing circuits in the TV will resolve the problem in a couple of days. But if there is an overall Green tint on the picture, it signifies a problem in the Video output stages, and there is nothing you can do, but call the technician (unless you know solid state servicing?)

TV lacks green, but has prominant red/pink

Getting the squematic will be the first step to take to become more familiar with the electronics inside,you can ordered by going to click on service manuals and give them the model number,they will then give a price and availabilty.The color processing uses a driver for each color and an output for each color too,the output are ussually placed in the crt board in theneck of the tube.the drivers and outputs are transistors most of the time but sometime the drivers are part of an integrated circuit.Please let US know if you need more help but place it as a new question.

Color mostly green

Sounds like tyo me that the picture tube is getting soft on ya!!. Its a common factor that occours with all tvs but mostly with zenith. A service tech might be able for a small fee rejuvinate the picture tube but theres never a warrantee with this type repair. Its not something a user should attemp to do as theres hi voltage inside this set even on the tube socket after its ubplugged for awhile. Seek the advise of a repair pro to see how bad the tube is. Good Luck
