1 Answer

Convergence prblm My red conevgence just went out one day last month. I tryed to adjust it with the remote but it would not adjust at all. I have read the posts and tryed to fix my problem by replacing the two IC "STK392-040" But this did not fix the problem. I was wondering if you think it may be the conergance module assymbly?

If you have replaced the "STK392-040", I would suggest to go back and use a magnifier tool 2X to 4X to inspect the solder joints. Also use a multimeter check for good electrical connections from the pads to IC leads.
Check the fuses for open conditions as well the low value resistors nearby the IC's or you might also need to solder touch-up some joints that do not look very shiny.
Good Luck.

Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts down
  • TV Chirps
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Red convergence way off


Hello,
I had the same issue as you pretty much exactly and so do others right around this last few weeks so I am thinking that this is a common problem with the product itself.

You can fix this pretty quickly with the link below. I bought it and it resolved the issue.

If you changed the ICs you need to adjust convergence, read carefully the instruction and alingn the lines using remote control commands. Is a long process. My tv loss convergence three times , i will never buy another samsung product. I told every body that i know that never buy another samsung product.

Convergence Problems


If you did not use heat sink compound then you probably have not hurt the new IC's yet but you should remove them and add the heat sink compound NOW. If the convergence IC's are bad then you will have access to the convergence menu but the adjustments will have no effect. The fact that you switched the IC's and got the same results shows that the IC's are good. If your red convergence is still way out when the new IC's are installed then the old IC probably burned out the low value resistor associated with the Red Vertical (RV) channel.
