Re: Bad color .

Turn the set on without an antenna, so there is only snow on the screen. Measure the 3 cathode voltages at the CRT, red green and blue. If the 3 voltages are about the same, around 175 volts, then the CRT is bad (purple picture means bad green gun). If the red and blue are around 175 and the green is over 200 volts, then there is a chassis problem, usually the video output transistor itself has gone bad or come loose.

I came home from work and the picture color is odd. The skin tone of everyone is a blue tint and I can't get it back to normal.

You have a bad ground on a color output transistor or a bad ground on a color output resistor. These are located on a board that is attached to the CRT. Also check the diodes on this same board, these may be bad as well. In worst cases the color output transistor and a diode will be bad. Thanks for asking!

I don't have any red tones. Grass looks yellow,

At its worse you have a color gun in the picture that is bad. On a positive note you may have a bad ground on the crt board. Or a bad color output transistor,or bad transistor ground on the crt board or even a bad resistor, or resistor ground. Have someone inspect the CRT board. Hope this will clue you in to finding a solution!

My tv only shows black and white no color, how do i fix?

You should check circuit boards for bad solder joints. It's possible to have a defective part on the board, open resistors, coil with broken wire or others. You could have a defective chroma chip or joint/part in the area. You should check the tv menu to make sure the color settings haven't been turned down first.

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.

Have 46 samsung dlp that has green lines all over the screen . menu still works but doesnt go away on the menu mode. the green is so thick that you cant see any picture in the background.

Red, green, or blue retrace lines ( a quote from "Notes on the Troubleshooting and Repair of Television Sets", found at )

Where only one color is showing, suspect an incorrectly adjusted individual background/bias control or bad part on the CRT neck board for that color.
  • Individual brightness/background/bias control(s) - mark setting of pot for the problem color and then see if a slight adjustment removes the retrace lines. See the chapter: "TV Adjustments". Of course, if this happened suddenly, the problem is not due to a misadjusted control though a dirty pot is possible - turn it back and forth - this might clean it and restore normal operation.
  • Component or connection on CRT neck board - insufficient voltage to or incorrect biasing of the video driver for this color can result in the CRT never totally blanking. Compare voltages and signals, and swap components between good and bad channels to confirm.
  • Blanking circuit - this may be a part of the video/chroma chip or separate. Check and compare waveforms of good and bad colors to determine if the blanking pulses are making it to the video output.
There is a slight possibility that a bad CRT may result in visible retrace lines. To eliminate this possibility:
  • Disconnect the filament - all evidence of a picture, raster, and retrace lines should disappear once the filaments/cathodes have cooled (15 seconds or so. If there are still visible retrace lines, the CRT is suffering from cold or field emission from someplace (may not even be the cathode).
  • Turn down the screen (G2) control on the flyback (usually). If one color remains no matter how you set the control, again there is some kind of weird emission from the CRT. However, if white/gray retrace lines remain, the problem may be in the screen supply.
(quote ends)
You will be greatly helped if you have a schematic for your TV set, and you may need to change some parts, clean some connector contacts and/or tweak settings inside the set, so remember the original settings before you tweak them...

Good luck

Color Problem after replaced Circut Board

When you replace the entire board in a Zenith TV, you must make the adjustments to align the new chassis with the old picture tube. You must adjust the CRT bias and drives as well as the horizontal and vertical parameters. On the older boards there were controls on the main and CRT boards but on the newer boards the adjustments are made with the remote control after entering the service mode. Tune in the shopping channel QVC, set the color and contrast to minimum and lower the brightness until the picture is just visible. Set the CRT bias settings for a pure black and white image, then increase the brightness and contrast to get a very bright picture and if necessary adjust the drive settings so that the bright picture is pure black and white. Return the video settings to normal and then adjust the vertical and horizontal settings so that the info boxes on QVC are centered top, left and bottom. If you are not sure that you can do that right then have a qualified tech handle it for you.

Tv turns on but wont stay on

There is a resistor on the CRT board that goes bad sometimes. I cannot remember the number but it is a common fault as the TV starts up and then detects too much beam current and shuts back down. If you have a multimeter, you can check the resistors if you know how the color coding works on these resistors. If you do not, take the set to a repair shop, as this problem, if this is the problem, should not cost that much to replace a 10 cent resistor. Good Luck
