Hello. You have bad convergence ICs. They are located on large,finned heatsinks. The #' on the two ICs ( red and blue drive )that need to be replaced start with "STK-" and numbers follow. The parts are available from http:\\www.tritronicsinc.com. Good luck.

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links 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

Samsung HCP4752W convergence board?


I couldn't decide whether or not to attack the IC Chips or the whole board, so I took out my S&W model 59 and pumped 11 9mm rounds into the whole chassis! Sets works as new as long as 'new' means comes with 11 bullet holes in chassis.
