If you replaced the STKs there should be no bows in the picture.Fine tuning is normal but severe bows means you still have a problem.I work on a lot of Samsung and usually I also have either a pico fuse open up that kills the -33VDC or +33VDC.The other thing that happens is that usually atleast 4 resistors that open up.These are 4.7 ohm resistors right in front of the amps.I feel that if you did not look any further than the amps, you still have a problem.I`ve never repaired a convergence amp circut that required major adjustments,usually just a little touch up in customer menu.

    If you want to fix this unit it would be eaiser if you took the advice of an actual TV technician.I know that you have alot of information thrown at you and 90% of it is wrong.I work on these things every day and I do not search the internet to waste your time with guesses.I can share information with you that will help get your unit fixed.The first question I have, is what was the complete number of the STKs that you replaced and where did you get them from?

Service code sequence is not a problem but service data handling can be and little mistake will mess the TV.
I would suggest to get service manual from HERE for free to do convergence data adjustment as per procedure.
Please download all 8 files and use WinRaR to unzip.
Good luck.

    You did not mentioned any further help you need? Now you have service manual and this is technical document of this TV with all tech details including service data.

  • Shahid Electronics
    Shahid Electronics Jan 20, 2009

    As you said, you can not access to free download link so procedure to access service menu is appended below...

    1. Turn on the TV, and then select “DYNAMIC” on the picture adjustment mode.
    2. Turn off the TV(STAND-BY).
    3. Enter the service mode by pressing the remote control keys in the following sequence:
    Display -> Menu -> Mute -> Power ON
    Note : If necessary, re-do steps 1~3.
    Initial display when the service mode is switched.

    Below is an image of service data screen... you will see...



    If you wish, I can email you complete service manual.

I have a Samsung Model PCN5425R Rear Projection TV. When I try to set the convergence, the red will not move whatever I do, but the blue works fine.


If it is rear projection set it uses either two of the STK-392-020 OR STK-392-040 CHIPS FOR CONVERGENCE OUTPUT.

BOTH WILL HAVE TO BE REPLACED; NOTE THAT THESE SETS ALSO HAVE "PICO" FUSES ON THE BOARD FOR EACH CHIP--no movement means one of the fuses is blown because the chip shorted.

This can be a do it yourself repair if you are handy; total parts cost if the parts purchased on Ebay is under 30 dollars.

Let me know if I can assist you and if you have any questions reply to the posting here.

Colors are out of line


When A REAR PROJECTION TV has coloured outlines or a 3D image the Convergence Circuits most likely need attention.

Replacing the output amplifiers (located within the Convergence IC's) allows the pictures to line up correctly, and no more color outlines.

This is the most common fault in all makes of rear projection TVs.

Some models of TV require major disassembly and considerable shop/manufacturer's support to repair because of their design that causes other power supply or vertical deflection problems. The poorly designed products require a "bench" repair that can typically cost from $350 t0 $700.

Some TVs are designed for on-site repair and have more reliable circuit design that does not usually cause damage to other parts of the TV when convergence chips fail. The ones that usually allow reliable on-site repair are JVC, Samsung, Sony and Hitachi.

It is normal to have some resistors in the circuit burn up or increase in value from the heat (from 2.2 ohms to 5 or 10 ohms). These resistors must be replaced with the right value or the chip may fail again.

This is not a simple repair like changing batteries or a fuse. Reading through the other posts shows many that try and end up with bigger problems.

Your JVC uses STK 392-110 IC's. Misinformed people replace the IC's with other "new and improved" IC's, like STK 392-150. These are devices with different characteristics and require different value resistors in the circuit. Replacing with the STK 392-150 will cause overheating of the resistors and a damaged IC.

If you are in Calgary, I can help. If not, get someone that has experience working on your JVC. My website is below with some costs and explanation.

My samsung rear projectiontv is showing in 3d


Hi, your convergence circuit has failed, the stk`s and any burnt resistors will have to be changed, if you know how to solder and un-solder proficiently and can use a volt meter it`s do-able if you don`t have this knowledge call a tv tech, generally runs $250 to $350 depending on where you live, call around and ask for estimates to fix the "convergence circuit", if you still have questions e-mail me back, Happy New Year, BMW Rider
