The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

How to do convergence on a JVC 56 in rear projection HDTV


. It is more difficult than batteries on a remote.

You access the convergence board through the inspection plate that is located behind the front speaker grill.

You remove the board, determine if any resistors are burnt, 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 you haven’t misadjusted it too badly, do the auto focus and it is back to where it was before IC failed. If it is still misadjusted badly, then resistors may be wrong value or open.

If you live around Calgary, try me instead:

or try the find a repairperson part of this website, maybe you will be lucky and someone is listed nearby.

Most rookies doing this job will cause damage and not be successful, and pay double for someone to fix their mess.

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:

Good Luck

HCN4226W convergence board


SAMSUNG Convergence Board

I don't recommend working on the TV unless you have some experience and knowledge relating to the safety issues and electronic repair. Many rookies will not successfully complete the repair and probably do more harm than good.

Open the back of the TV. The board is in front of you, a small separate board with small plugs attached. If you think you are competent enough to remove it and replace it without damage to yourself or the TV, go for it.
Website below gives some description of costs with in home repair of convergence problems.

If it's really bad and happened all at once, your convergence amps have failed would need to be replaced before you could correct the issue with an adjustment.
