Question about Daewoo DTQ-27S2FC 27" TV

1 Answer

Rainbow colours appear on the screen after it fell over

My mother knocked her TV off the stand whilst cleaning. It now has a rainbow effect of colours in the top corners of the screen, other than this the picture and sound are fine. Is this something easy to fix or should she get a new one (out of warranty by 2 weeks). Thanks.

Has a double picture and looks rainbow

A double pcture with two different colours??? more seriousely the rainbow effect could be of an appature grill un hooked in one of the three tubes (THIS IS DANGEROUS IT COULD IMPLODE) you should have a proffessional looke at it and you should NOT USE OR MOVE the TV until then.

Good luck!

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.

Colour is rainbow effect on tv,starts as a semi circle near the bottom of screen then has another two/three colours up the screen?

May be PURITY on the tube, an effect of older CRT tubes caused by a build up of magnetism around the screen, easilt cured with what is known as a magic wand. An electrical wand that produces a magnetic field and is waved in front of the screen to de-magnetise it.
Ant TV engineer can do this for you.

I have a rainbow of color about the screen. The TV fell out of the stand and now the color pattern is messed up. It fell face down.

sounds like a degaussing (magnetizing) problem.could be that the posistor inside the TV set got loose when the tv fell down. If you have experience soldering electronic components, you should be able to fix it by re-soldering. Otherwise, call a tv tech to do it.

Colourful picture

Discoloration of this sort is caused by magnetism. All CRT TVs (like yours) have a de-gaussing coil around the picture tube that de-magnetizes the screen (more specifically the shadow mask) every time you turn it on. It is likely that the circuit that controls this coil is at fault. There is probably a cold solder joint where it connects to the main circuit board.

The other scenario is that someone (small child generally) has run a magnetic object very near to the screen, magnetizing the shadow mask (inside the picture tube) and causing a rainbow effect. This is less likely if the rainbow effect is a nice even circular shape. Generally if it's been magnetized by a magnet as described the discolored areas will appear blotchy.

In short, if you have some electronics skills, get in there with your soldering iron and touch up the connections to the de-gaussing coil. If not, find someone who does.

Rainbow effect has more to do with color wheel style and speed.
