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.

Dropped lcd tv


HELLO!
The problem with LCD panels is once they have a good "knock" they've had it! With the set off look at the screen and if you see a place with lots of colours (like a rainbow as it were) - it's gone.
To get an LCD panel replaced is VERY expensive much more than a new set is worth. Probably not what you want hear, but that's the way it is!
CHEERS! (:-).

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 dropped my 27in phillps magnavox


if this is a distorted kind of rainbow aura affecting the colour, you need to de-gauss the screen - a good tv repair man will have the mains powered magnet to fix this - and shouldn't charge alot.

Rainbow effect at top of screen


This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you wish to attemp the repair yourself, please let me know and I'll look up the parts and provide additional details and instructions. Also, please confirm your model number.

Thanks,

Dan

Rainbow colors in top corners of tv


Hi

in this issue you have defective crystal color carrier or you have defective Jungle IC. But the best is to diagnose first.

Thanks!
