Good Day, tree64;
More than likely the convergence problem the TV has wont be resolved by adjustments. In your situation, moving TV, the problem most likely is poor solder connections on the convergence IC's. They are large devices attached to very large heat-sinks, and have numbers on the IC'c like STK 392-560.
If no poor connections....replce.
Good Luck, big IRISH.

I have a HCN4727w samsung. Red/green shadowing. Bowed image


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

Ws55809 tv picture bows at top and bottom. Also has shadows. Is it the bulb and where do I get one.


You have a convergence problem. The 3 picture tubes are fine. The small signal module needs reworked. The board with all the rca jacks.
