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,Akai,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

Time to get a new TV

sounds like the degausing coil isnt working or you have a speaker close by.

Replace D805 (?) Thermistor for permanent fix, manually
degauss with coil is temporary........T.

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

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.

sounds like you have a deguassing problem with your TV .. have the repair person bring out a deguassing coil and see if thsat helps.. This will only be a temp repair as you will have to have the problem that caused this to be fixed. good Luck

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!
