Question about Panasonic CT-27SF37 27" TV

Panasonic Color Rings

There is a large pink circle in the middle of the screen, a blue ring around that, and then a green ring around that one. What is wrong with this thing?

Is that what it is? The black and white seems fine--you can see the picture, the color is just goofy.

Thanks,

I seem to have the same problem. I've read the solution below... Does having a bad picture tube mean the whole TV is a write-off?

It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners?
If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened.

My tv has a pink blob in the centre with a blue large ring around

Either someone got too close to it with a magnet or you have an output problem.

Rings of Color

You will need a degausser. Check out Wikipedia for the definition. Look on ebay or your local TV repair shop. Cost should be $20-$100.
