TV screen gone funny colours

[1211Dana1211]

My tv has suddenly gone weird. The colours on the screen are all purple and green. Is there anything that can be done or am I now without a tv? :o(

Cheers for any help.

Hit it with a large haddock.

That was my second choice!! How did you know? Have you been spying on me again?!

I was reckoning that it could be the tube, as this has happed before (not in quite the same 'oil slick' way though).

Am I going to pay a fortune for that to get fixed though. Although it would cost a lot to buy a new tv of the same size.

Could it all go tits up from now on and this is just the start...

ACK!

Turn it off for a couple of minutes and then turn it on. This will demagnetise the screen. If it's still the same, get an engineer to look at it. Most likely it needs a thermister and the repair should not cost too much. Depends how old it is.

How big is it?

Sounds like you or somebody else may have put a magnet near the screen (or maybe a speaker as they have magnets in them). If that is the case then move the magnet away from the screen and it should sort itself out.

you have checked for loose connections ?

Hey thanks for the answers...

It has been turned off for a bit when I was out and so on and it's no different. I am watching it in black and white at the moment.

The screen (visible) is 26" corner to corner.

No magents that I can see nearby and nothing had changed before it broke. No speakers either. I live alone so I don't know how that could have happened, although I am a bit dim at times!

I faffed about with the tv when I noticed the problem and nothing seems out of place. It is in the same state whether DVD, tv or video.

Just to make matters worse my mobile phone has also cacked up!! ****, ****, ****!!

If it has a button marked "DeGauss" press that and that may sort it out. If not you may need an engineer to Degauss it. Basically wave a vey powerful electromagnet around in front of the screen, this often sorts it out. This is the first possibility before deciding that the screen is conking out.

Maybe the red is hiding leaving blue and green. This could be simple as a poor conection (this is where a whack might help, if you don't knock something else loose) or serious as a new screen, (buy a new TV). If somethings loose or a small part is bad may be worth repair if you can get a "$?" quote. If the black and white looks normal (not tinted) the screen is probably OK. If it is tinted it still could be something else.

Thanks again for the aswers!

Where would I find a "DeGuass" button? Remote or tv? I am going to faff about with it again over the weekend to see what I can do (or can't!).

The black and white is tinged. There's a bit of purple and yellow in the top left corner.

Oh, and why do I have stars at the end of my ast reply?! I didn't do any swearing. Or mention anything after my phone!!

It's not that common for a tv to have a 'degauss' button. The degauss circuit works automatically when you switch the tv on and demagnetises the screen. The circuit is controlled by a thermister and this has probably failed. As I said, it is not a big job, but an engineer will charge labour. I haven't been in the trade for a few years, so I don't know what they charge these days, but I don't think you should pay more than about �40 or so. They'll charge more if they have to come to you, though. Doesn't sound like the tube's at fault.

Do you have new neighbours by any chance, when our new enighbours moved in they put thier tv on the wall backing ours and it made our screen change colour. They fortunately changed their placing before we said anything.

I had a similar problem when the scart lead was not quite pushed in enough. Hope this helps
