The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

Take it to a TV shop that have a special Degausser coil and they can professionaly remove the spots. Also has the sete been dropped? If so the tube could be damaged

RCA 27V520T 27" TV has a red tint


Keep down the colour completley, and note whether you get a pure black and white picture. If not adjust the cutoff control, normally these are preset controls fitted on the base card of the TV; to adjust the excess colour seen on the screen to increase or decrease; so that you can get a clean black and white pocture with no tint on it. it is a time taking task; and should have some sort of skill and more patience. Sometimes you may have to retune other two cutof controls [Blue and Green], too to get the desired effect.

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

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!

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Green & red tint


Most likely nothing you can do to fix this. CRT TVs use 3 colors to make an image on the screen (Red, Green, and Blue). If you're only seeing red and green then chances are the blue has stopped working. You can replace certain parts in the TV but for a 27" TV you'll probably end up paying more for the repair than a new TV.

I don't recommend taking the cover off and trying to fix TV yourself without training. CRTs have a lot of electricity stored in them (even after turned off) and you could accidentally electrocute yourself.

Rca tru flat tv has a red picture


Is your video input (from cable or satellite or fiber optic, etc.) coming from a coaxial cable, a component cable (red, green, and blue connectors), or an RCA cable (yellow connector for video)?

If you can, try an alternate input method and see if that makes a difference. Does it happen when watching DVDs or tapes, or when playing video games, or just when watching television?

RCA CTC203 no red colour


Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
