Funny colours on my tv screen

[natalie149]

Ok,let me try and explain my question, my little boy has just been given a set of them "Oidz" things, you know them magnetic thingys that stick together, well he put them against my tv screen and now i have green and blue blotches all over the screen, ive tried putting the magnets over the blotches to see if they would dissapear but they just moved the smears about like an oil spilt on water, what i want to know is , how can i get rid of these, i really dont need to have to buy a new tv just before christmas, any ideas would be appreciated? Thanks

Yep, that'd do it. You're tele is a write-off.

No, just kidding. It needs de-gaussing (de-magetising). Tele's have de-gaussing coils built in. They usually trigger when you first switch it on. Try that. It might take a few goes if well magnetised.

If your tele has an on-screen menu system, there's sometimes an option to de-gauss in this.

I don't exactly know the answer to your question, but my best guess is that the magnets ha somehow damaged some vital parts of your television.
Try hiring a repair service.

By sheer coincidence I posted the following link which may prove helpful on another thread a few hours ago...

There are two possible causes for your problem, one fatal, the other fixable. If the magnets are of average strength, they will have just imparted some magnetism to the aperture grille, and this can be fixed by degaussing. The screen. See you TV instruction book for how to degauss. With some TVs it's a menu option, but with my Sony it involves disconnecting the TV from the mains and reconnecting it (it's not enough to switch it off). When the degaussing circuit operates, you will here a loud sort of buzz, and the picture will wobble for a few seconds. You may need to repeat the operation a number of times to cure the problem.

The second possible cause, is that the magnets gave actually distorted the aperture grille (they are very fine and delicate). If this is the case, I'm afraid that the TV is now junk!
