Depending on where you bought the ICs you could have fried the new ICs when powering it up with burnt resistors as the green is controled by both ICs one IC controling the horizontal green Convergence and the other IC controling the vertical green convergence. Have you checked all the convergence resistors out of circuit?

Model 51S715: 2 issues: (1) Screen is bowed at top...left and right edges turn down and are black. (2) picture color will turn green randomly. If I turn tv off and leave off for a while the color goes...


Ur tv have a problem call convergence,it dying about to be dead.The tv convergence board 2 STK Convergence ICS and some or all it resistors require changing to solved the covergence problems.U have tools,soldering iron,solders and know how to do soldering?Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

Thers a bow at the top and botom of the screen. the multi convergents want stay. the red and green want keep ther ajustments


your convergance amps have failed they are a large ic mounted on a large heat sink replace them and the 2 burnt resistors you will find

You need to replace your STKs Big black ICs 392-020 replace both of them also check 2 resistors 2,7 ohms they may be open.this is a common repair iob.

Tv looks green and bowed, also has double image


your tv is having a convergence problem, nothing you can do aloneyou wll need to call a tech, there must be 2 bad ic and some resistor burnt

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 Perfect Focus 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

If you cannot converge the red and blue back to the green through the convergence menu, Then you have worn out convergence ICs you will need 2 of them at about 10.00 each. Takes about an hour to remove the old and replace with new ones, but also check the resistors right next to the ICs usually 1 or 2 of these burn out with the ICs. Let me know if you need more information.

Blurred picture


Sounds like a resistor in the convergence circuits or covergence amp ICs them selves. Usually the ICs will distort the picture. My guess would be the flame proof resistors near the ICs 1 or 2 may be oen. Let me know if you need anything further.

Covergence and Bowed Picture Problem


can you adjust any color of convergence in user menu blue, or red up or down left or right. if you can make any up or down left or right adjustments on any color then the likelihood it wont be a convergence ic. it would be a output resistor. so see if you can get any movement. with it being bowed i was suspect an convergence ic.
