It seems you have a loose conection in the Horizontal deflection circuit,I will start checking the horizontal driver transformer then any overheated areas in the power supply and overall chassis.If you are familiar with tv service you know where to look but if you are not be safe and call for help,try no to use the set or the problem will be worst.

Projection sets have two very common problems.

The first common problem is convergence

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...

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

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

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Edges of Picture & Text Sloping

This mis probably a cold solder connection in the horizontal circuitry called the pincussion. Theres a couple of coils and resistors that overheat from time to time and the solder connections get loose. Not really for a handiman has this tv has hi vboltage inside even when turned off. Shouldnt cost an arm ans a leg to fix if the repair shop knows what they Are doing. Good Luck
