Your problem sounds like someone got a magnet too close to the CRT. This can be removed with a degauss coil (which you probably do not have) or it will eventually go away if your built in degauss circuit is working. Everytime you turn on the set the circuit degausses the crt so colors can be displayed properly. If the circuit is not working you will need to have a tech repair it.

SOURCE: Has sound, no picture, just color

usually if the tube has gone you will get no sound and all you will get is the telly on standby so the best thing to do is take it to repair shop and they should tell you for free what is wrong but usuall it costs more to repair than it does to buy another one sorry i couldnt be any more help

Vizio 50" Plasma VP50HDTV20A comes on with sound but screen shows rainbow colours before pictures comes and picture is blurry when on and not in full color. All the inputs have the same display.

If this is an old Plasma TV that you picked up somewhere, it may just be too old. Plasma screens degrade over time.

New plasma TV's are not common anymore, so I am assuming this one has been around for awile.

If it is new, take it back to where you bought it.

Rainbow color effect appears when Samsung LCD plays Wii or DVD

Hello, I have a question which video inputs are you using for your DVD and Wii connections? The reason I ask is because this sounds like video distortion cuased by noise. If possible can you send a picture of the screen when it has this problem and send which video ports are being used? If it is noise in the video you may have a saw filter problem, or a decoupling issue. In any event I'll know more once you send those pictures and which inputs you are using for your DVD and Wii. Thank you, Shuttle83 http://www.electron-age-technologies-llc.com [email protected].com

Bad color

If it is a glass crt then you need to have the set demagnatized with a demagnatizing coil. All tv shops have one. This is worth fixing and usually at the price of a service call.

Sony Trinitron Color Rainbow

Usually when a tv is dropped the phospher screen inside the picture tube will detatch making the rainbow color This cannot be fixed as it requires changing the picture tube. Only other thing is demagnatize it with a demagnitizing coil (used by tv techs) but not likely to fix it since it was dropped. You have a bad picture tube.

Same as other poster: Player only plays black and white

It sounds like the circuitry which actuates the color drives for the screen are not working, this would ba analogous to adjusting for a B&W picture on a color TV you have color but the screen shows black and white. I would get a schematic for this set and measure the voltages on the color processor that connects to the screen since you know that the external jack has color. If possible I can help you troubleshoot this, if you need me to help out.
