Question about Panasonic CT-27SX12 27" TV

Rings of Color

I turned on my tv tonight to find the color is distorted into rings. The center is a solid green and takes up most of the screen surrounded by a blue and red ring. Is this fixable (at a reasonable price) or do I junk the tv?

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.

Samsung HCN4727W Rear Projection TV, green screen, audio works

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

*Dull looking picture

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. Stargazer

Color rings on hdtv

Sounds like a CRT (picture tube) that did suffer a bit of a blow to it. The rings are caused by the thin sheet of steel inside of the CRT called a shadow mask being warped. The other cause for this is the internal degauser in the TV comming on and staying on too long causing damage to the CRT. Either way the CRT is over $400 plus you will need to find out what caused the issue and repair that first.

Possible problems: 1. Ghosting is caused by an ingress of off-air signals into the TV through the cable system, or the TV's antenna 2. An F-connector may be loose 3. The cable plant may have a "leak" in the area Solutions: 1. Check and hand tighten the cable fittings to the TV set and VCR. 2. Remove the antenna from the VHF terminals when cable is used. 3. A converter or A/B switch may be needed to correct the problem (A/B switch enables you to bypass the set-top cable box or descrambling cable box and tune all unscrambled channels directly with your TV, antenna, or VCR). good luck!
