Unfortunately, the complete convergence amp board is no longer available from Samsung. But the board is available from ptscorp.com. Go to the website, get the telephone number, ask them what convergence Amp board you need and if they have it. If you know how to solder and unsolder, you can simply change the convergence amp IC's, on the main convergence board. The IC number if the IC's is STK392-040 Good Luck.

yes the convergence problem leaves a shadow of red or blue like an outline around the picture, sometimes part of the screen some times the entire screen.

You are going to have to reconverge your TV. Order a service manual and it has a 20 page set of instructions on how to set up the convergence for the first time with new convergence amplifiers. Once you have done this procedure the "perfect picture" one touch control should be enough to keep it in convergence. You must have the original remote control in order to do the convergence procedure.

Good Luck.

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
*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

Double vision on my samsung HDTV 1080i
If one or more of the colors, red, green or blue have separated from each other and you can`t correct the problem using the convergence procedure as described in the users manual, that would indicate you have a convergence problem. Bad solder connections on the convergence output chips are common. If the set had a rough ride down the stairs while moving, that may have facilitated in exposing a preexisting condition. However, the most likely cause is the natural failure of one of the convergence output chips and or related components and not the move. The fix is to have a qualified technician address the problem. This is not a do it yourself job.

Blue shadow and lines
This would apear to be a convergence issue ..sometimes you can go into settings and converge it manualy.. if this is to far out of range. a service tech will have to adjust inservice mode. if the convergence cuircits are not failing. if so then there are cuircits that will have to be replaced. is this just a blue shadow?.. is there green or red shadows. if not it may not be a major repair.

BLUE DOUBLE VISION
It sounds like you may have a loose solder connection either in the convergence circuit or the pincushion correction circuit. If you can't visually locate it, you may need a service manual and test equipment to track it down. I doubt that changing parts will be the cure if it is an intermittent problem.
