Double picture


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
*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.

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

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

More than likely you need to replace your IC's on your convergence board. Im not entirely sure on this model, but it's probably STK392-110. There are a lot of people that recommend that you replace them with STK392-150 to ensure a longer life.

Convergence green lines


Closely inspect the board for poor solder connections. Also someitmes the resistors will not show any signs of being bad even though they are open. It is wise to measure them but you need to disconnect the convergence yoke plugs to ge a good reading.

Have you got the cable connected properly and attempted a consumer convergence in the menu? If you've attempted that and are still having the issue there may be other components on the Conv Module that have failed.
