My color isn't normal. I can't see red and green properly. I've tried adjusting the settings but nothing works.


If you have had a vaccumn cleaner too close to the tv, then you may need what is known as de-gausing. This will bring your colours back as normal. Seek advise from your local service engineer.

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

No red


Losing one colour probably means failure of electronic components related to the particular colour. It is unlikely adjusting the red settings will fix the problem. Even if it did, the colour balance needs specialist equipment to properly set up.

Color problem with TV


Are you getting Green or purple or pink patches all over the screen?
This could be a problem of Degaussing. Have you placed any Magnetic source near the TV recently? Some Tape recorder or walkie talkie or a Speaker, etc? The Magnetic field created by any of the above sources can cause coloured patches over a colour TV screen.
It also happens if you shift the TV from one location to another.

The third possibility is that the Picture Tube's Red Output stage gone faulty. Unless you are a trained Solid state Electronics Technician, there is nothing you can do. Better go for a trade in.

How do I decrease the amount of green in the picture?


Unfortunately this model has a bad CRT. If is 3-4 years old and the greenish picture is in all inputs, for sure the picture tube is gone. If the picture is green only in component input check the connections for the blue and red cables.

RCA F31317 lost blue in picture.


this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!

Loss of colour


With the set being 12 years old, I'm sure the picture tube is near the end of its useful life. You probably have a defective semiconductor, either an IC or transistor that has gone up giving you no color, but with the green picture, it is not likely worth repair.
