Replace both STK ICs they are Big Black ICs and will have Part Number on them,example STK392-110 .You will also need to check the pico Fuses in front and back of ICs they will look like resistors but will be Yellow or Green 5amps-7amp pico fuses. Mats Electronics has Parts 1-800-628-1118

"Perfect Focus" problem on Samsung HCN4727W

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

I have a KDP51ws550 tv that has convergence problems. Flash focus would not work and neither would manual convergence. I replaced the both convergence ICs and checked the pico fuses, turned the unit back...

Check your soldering. Check the vertical power board on the far left when looking from the back. It has fuses on it as well.

Depending on quality of STK chips, they could have been bad or failed right away. Best things is to look at the schematic, verify what colors you can move and see which STK chip is not functioning.

If both chips are not function after replacement, likely a fuse. Be sure to verify the resistors next to the STK chips.

Flash Focus does not correct convergence problem and i cannot manually adjust the red convergence to proper alignment. Red does not move laterally only vertically. Picture is offset to the right with red...

No,any colors lines mis alignments.The tv convergence board parts are dead.The 2 STK convergence ICS and some or all it resistors are dead.These parts must be replace on the tv convergence board.To solveved convergence problems.The shop,will cost u $300-350 for parts and labors.

Hello, my tv looks 3d

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • 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 off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Hello,
Your problem description is not clear.May be you have convergence problem with your unit.
Press flash Focus button on the control panel of the unit.If the flash focus complete one full cycle there is no problem with convergence amp.
Inorder to adjust convergence you need to enter the unit into service menu.
