Re: Panasonic Color Rings
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.

If they are large colored circles behind the picture scenes, mine had it too. Fix was as simple as service technician plugging into the EPROM and loading a software update. Picture then was better than day1.
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.

you must have placed speakers around your tv. your tv tube has gotten magnetized.you will need a degaussing coil to remove those color stains if you do not have a coil call a tech to remove it for you.good luck.
check the degassing circuit and replace the degassing relay, then use a degausing ring to bring the colors back to normal you should be ok. good possiblity a bad solder connection at the degausing circuit themister.
