Hi,
Convergence IC would have number written on it as STK392-110, there are two big black ICs mounted with aluminum heat sink on A circuit board.
required IC is available in Part Store, click that link to see an image for easy recognition in tv circuit board and price info.
Hope this info will help you.
Let me know if you have additional question.
Thanks.

    =======================================================

    It calls A Board, it also has Tuner mounted on that board where Coax Cable goes in tv.
    Once you take off back of tv, you will see convergence ICs easily in good light.

Convergence problem


Usually what happens is that the convergence IC goes bad or the fuse going to the convergence ic goes bad. Pico fuses they are called sometimes open up. You may want to open it up and pull the board out and check the solder connections on the convergence IC. Sometimes these get fractured or cold soldered and aren't making connection to the PC board.
Let me know if you feel comfortable with pulling TV chassis out or pulling the board that has the convergence IC on it out. Then you can resolder convergence IC OR replace it.First thing i would do is check to make sure there is between 22vdc and 25vdc on the fuse or the convergence IC. Let me know if this helps out any.... Sincerely HDTV GURU JAY

Television has double images like 3D, and bottom half of screen has a concaved image.


Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.
Thanks.

My samsung sp42w5hfx the picture is like its in 3d can i fix it and how


This is a convergence problem and is quite involved to fix. I suggest you get a tech/ They have the right tools to generate a pattern to correct the problem as well as warranty on the replaced boards required to fix this problem. It's not a DIY for amateur

Please rate my help++++Thanks for using FIXYA

The green color is off. I am thinking that it is the auto convergence. I want to try to fix it my self (I love to do these kind of things) but I do not want to buy the wrong part.


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300
To Find the IC's look for 1 or 2 large (4in x4inx1in) aluminium heat sinks. the part # is labelled on the face of the IC itself

Problem with TV screen?


Good Day, deon453;
Sounds like a convergence problem.
Corrective Action: Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version.
Good Luck, Big Irish.

How do you install the convergence part on a Mitsubishi WS55511 big screen tv? The part has prongs on the bottom but I don't know how to attach it.


you must de-solder the output IC first. Then I would suggest that you remove the heat sink by removing the philips screws holding it to the pc board. you will find white heat sink compound on the bottom of the heat sink. clean this off and remove the output IC. put some heat sink compound on the new IC and install in in the holes on the pc board. be careful removing the solder on the pc board. I like to use solder wick. Install the new IC and solder it up as the old one was. remember to check the convergence in both analog and digital, as you have to converge both for it to remember the settings. Hope this helps. TV repair guy :)

Philips 60pp9202 sound but no picture


Sorry no pic, but if you look from back of set on deflection board(board with HV transfromer)big part with about 4 wires coming out going to your picture tubes. Looking close to leftside of board the last IC with heatsink shield standing up has a small 7 pin ic if looking on it you should see TDA8177 or something to that affect. This is the verticle IC. Since you have found the IC's (convergence) then the only thing left is to look for open fuses like 1300, 2004, 1900 etc and see if open. Concerning cost if you buy from www.bluestaronline.com these part are inexpensive so it wouldn't hurt to buy all. Rule of thumb, if set has color problem then Convergence IC, if no problem just went out one day while playing fine then Vertical, then the alternative if no sound the audio area, which is not common for this set. Hope this helps!

Tv won't turn on


Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck
