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.

Rainbow of colors on screen


I just had a rainbow of colors on my tv screen...i thought it was a problem with my TV...however the screen went the "sign off" screen (verticle lines-red/blue/green) Then all of a sudden the picture came back and all was back to normal again.

So I say it's nto your TV it is a station problem!

We have a big screen tv that is a phillips magnavox and we have no picture but great sound,on our tv screen it has a rainbow color line down the middle...what could that be????


You need a professional.
Your degausing circuit has failed.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Older big screen tv's


Its probably going into protective shutdown ue to an over voltage condition in one of the operating circuits. My guess would be one of the regulator transistors or a leaky diode

Color on my big screen tv


sounds like you need to have the two convergence IC's replaced. These are soldered on the main board. Good Luck
