I have a Philips Matchine television which does a similar thing, the problem is in the receiver part of the set, where I have traced the Video signal with an Oscilloscope to a particular Chip (Integrated Circuit). By increasing the Contrast to maximum the picture can be brought back again, but still lacks contrast. The fault is varies as the chip warms up. Therefore you can locate the chip by cooling or heating it from a special non inflammable spray can.Have you tried the scart input which may work OK, then you can use the television as a monitor, as I do. Cost of repair is not worth it.

Rainbow screen aiwa tv,, screen shows different colors like rainbow// brushing a magnet infront of the screen fixes the issue temporary


Picture tube is magnetized. Manual degausing is required. already you have done this.

Since you say it is reappearing, you have to check the following.

1. Relocate the TV or relocate if you have placed any tower speakers
or home theater speakers close-by.

2. Check whether auto degauss functioning OK. In the MENU
check whether you switched off auto degauss option. If it is OFF
enable it to ON.

3. Finally re orient the direction of your TV and watch the rainbow
effect. Switch OFF TV, wait for 20 mts, and again switch ON.
Repeat the process. It should disappear.

Magnetic toys or any other devises using magnet will cause this problem.

My son was bouncing a small ball against the screen and then it went to looking like a rainbow. Would this be the picture tube?


He may have caused some type of damage to the picture tube, but usually rainbow effects happen when magnets are present. Perhaps the ball became charged with a large amount of static, which then discharged across the tube, damaging the controlling circuits.

Has rainbow lines on tv screen


shadow mask is warped. tv might have been dropped. crt is bad(picture tube). try deguassing it. if you dont know what that is take it to your local service center. the rainbow effect is a magnetic field of some sort. try unplugging and move to a different location. could be a speaker too close to tv.

How to fix TV


I have a large black square obscuring the picture. You can see the picture in 1 inch border around the black square. If I reset the input switch, the black square disappears for about one second (the picture is momentarily perfect) and the black square appears again. It is not the cable box because I wired the cable directly into the tv. The same thing happens when I try to play a DVD. Any insights????

My picture has a rainbow look to it


Are there any external speakers next to your tv? The magnets in the speakers will cause this effect to happen. If you do, relocate them and the pattern should go away.

Rainbow screen then powers off


The degausser cricuit may be the fault. The degausser coil may be staying on, and thus forces a shut-down. It is also possible to have a power supply fault that can cause a similair effect.

The set will need shop service.

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck
