This sound very simple. You might need to DEGOUES your tv. Try to find a small degouesing coil at a parts store. This will take 2 seconds to fix. Just plug in the coil and wave it in front of the screen, pull it away from the screen, and it is fixed.

Green and yellow images appear to be orange on the screen of my Sony trinitron wega tv. The CRT does not receive green colour and hence there is no green colour on the screen


hello my fellow electronics tech. it seems that you know something about electronics. i would check the color transistors on the circuit board on the back of the crt neck. i believe it is supposed to be around 5v per transistor. one way to be sure is to match voltages with the other two amps and see if the green has no voltage. you then make a resistance check. make sure all power is off and the voltage has been drained from the set. check the caps by the color ic also with an esr, or use your ohmmeter.test your color ic for correct voltages that could cause erratic color problems. thank you very much and please rate my solution

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

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?)
