Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....- Screen looks 3D
- Colors don't line up
- One or more colors can't be adjusted when using the convergence menu.
- Screen is bowed or warped.
- TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy
Projection
TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and
green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

i do not understand your ways of fixing this problem?
Hi I had the same problem. If its the green thats off, you're going to need an expert if you don't feel comfortable digging into the back of the unit. In my case two soddering point gave up, causing tow resistors to go bad. the upshot is $350 In repairs to have the unit fixed, and re-tuned to set the green convergence correctly. If you want the manual you can get a free manual from the panasonic service site. just do a search on your model number. good luck
