    I called PTS and sent the board to them, the board can not be repaired due to the traces.

    Does anyone have a good board that I could buy?

    troylove11, I had already tryed PTS, they did not have a board avalable, not sure where else to look for a used or new board, Thanks for you help so far....but I still need to find a board.

Have a Panasonic PT-47WX53 47. It's probably as old as when it came out. I've messed around with the convergence before but it was never un-fixable. Then a couple a days ago I came into the ro


yes and also possibly the low ohm resistors. You can get the PT53WX53 convergence kit which fits your model from www.tvrepairworld.com which has the 2 ICs and associated resistors plus the CD with repair instructions.

Hi, I have a Samsung HCM422W projection Televison and my convergance is not properly adjusting. It will not allow the red to fully adjust. Along with that it seems like the picture is kinda concave. Im...


MOST LIKELY, if convergence will not adjust in some part of the screen and or is bowed looking:

You need to locate the two convergence chips (usually STK-392-020 OR -040 THAT this set should use.

Most of these smaller Samsung sets they are located on a small circuit board mounted above the main boards--see photo of typical chip---should be two side by side.

If they are not located on that separate board, it will be much harder to remove/ replace them.

If the photo or this information helped you rate this solution as very helpful as I do this here for free.

THIS IS A TYPICAL CONVERGENCE CHIP--YOURS WILL HAVE A DIFFERENT NUMBER LIKE STK-392-040 OR -020.


TOTAL PARTS COST ON EBAY WOULD BE UNDER 20 DOLLARS.

Lots of Blue shadows off to side. concaved picture almost


HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

Problem with Samsung TV


SAMSUNG Convergence Problem


It looks like blue convergence. Look at menu, select convergence and see if blue top is bent down on convergence adjust screen. Probably won’t adjust.

Some Samsungs have convergence IC’s on a separate convergence board in the back of the TV. Others have the IC’s mounted on the main deflection board. Either way the board has to be removed to get at the dud IC’s and associated burnt resistors.

You remove the appropriate board, determine if any resistors are burnt or damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If the unit has not been misadjusted and everything is OK now, running the auto focus may put the picture back to it’s previous stunning quality, as it was before IC failed.

If after self or autofocus it is still misadjusted noticeably, try the customer convergence adjustments. Operators’ manuals are available on web through searching.

If convergence can not be adjusted properly, you messed up chip install or resistors may be wrong value or open; or it needs major adjustment.

If you live around Calgary, Alberta try me instead:

Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck

Update and a few questions (Convergence Problems - VS-55601 55 in Projection)


yes, they go bad interment because they have a large current go thru them and they generate heat, they are mounted on a heat sink with white silicone to help disapate heat. replace both not just one, try MCM Electronics get heat sink compound also
