    I've the same problem as Sept 28 Guest. The Reds come and go. If I whack the side of the TV, the Reds come back....for a while. Glad to see I'm not the only one. Too bad about professional help though (I've nothing hooked up to it other than the DVD/VCR combo and a cable box).

Dan (above) is partly correct, that a resolder, COULD solve problem, but also BE WARNED!

HIGH VOLTAGES Inside the Cabinet

The Circuit components of the main circuit board could be up to 500 Volts at certain points.

THE CRT Voltage Doublers can have a lethal jolt to any skin that may make contact at the wrong points.

A Soldering Iron may be Grounded through the probe to earth (ground) and could potentially cause a problem when re-soldering the board.

GET THE SERVICE MANUAL or a Similar TV set manual.

Understand the building blocks of the TV and where the 'discharge' points are for the safety aspects of servicing the tube.

IF the above makes you skittish, bring TV to competent service shop. The $20-$30 is far cheaper than a trip to the burn ward or cardiac section of your local hospital!

For the problem above, the red may not be getting enough 'signal' from the video section.

The Red Filter Circuits could be clamping the red signal if a Capacitor has dried out on the main board.

a quick test is if the Video board has Composite Video inputs, What happens if a Video Source (VCR - Video Game?) is connected to the Video In.

SOURCE: The colour has gone wrong on my tv.

This problem could be as simple as poor solder connections on the board that sits on the back of the CRT to a defective driver transistor for the red gun to a bad picture tube. It is possible that this is an inexpensive repair (solder connection or defective transistor) or expensive (bad tube). If you can solder, try resoldering the CRT board connections and see if that resolves the problem. If not, then have a shop take a quick look. They will be able to determine whether the CRT is bad or not.

I just plugged in kworld pc to tv and connected to tv.i have a picture but has lost its colour i have a green color now. no matter what i do to settings it is still green. what has gone wrong? is there any...

If it is all green, it is usually just the connection that is not plugged in properly - disconnect the cables and re-connect and make sure you did not bend any pins on the connectors. Also make sure it is not a lose connection in the cable (i.e. a damaged cable) test this by bending the cable at the connector - sometimes u find its just a damaged cable that can be replaced.

The colours on my tv have gone pink and green

Either your picture tube has gone bad or the transistor or IC on the crt board, on the picture tube, that feeds the blue gun has gone bad. You would have to test the transistor to see if its shorted or open with a multi-meter, or check the voltages to and out of it. The voltages are around 200v and dangerous if touched, best left to a proffessional. If its the transistor/IC it would be a cheap and easy fix by a repair shop, if its the tube, you may want to go tv shopping.

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.
