The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck

Each convergence IC has a fusible link going to the IC. On the foil side of the board you will see the fuse size, usually 3.15a. Check both with an ohmmeter, like you would check a normal fuse. Replace the one that is open and that should take care of your problem. Good Luck.

I would replace both of the STK392-040, and check the resistors with one side out of circuit. The variable resistors are melted at the factory after the resistance is dialed in. I would check the resistance on it before replacing it. You can get replacement ICs and resistors at the following link and they provide free instalation instructions.

SOURCE: Samsung Rear Projection Problem (not convergence)

The tv has 2 focus adjustments for each tube, mechanical and electrical.

1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.

Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.

With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look

When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.

2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.

In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.

One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.

With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.

Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).

You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.

If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.

If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.

Lots of people try to buy a "board" for this kind of repair and it is a mistake.

If you have a convergence problem just get someone to replace the two STK-392-040 convergence chips this set uses.

Yes, there are two fuses near them that need to be checked--you can get all (both chips and the fuses) on EBAY for less than 20 dollars.

A replacement board will be more and I have seen several people who suddenly had new problems who did this.

Replacing the board sounds better but usually is not.

This set is not the most easy to work on but replacing the BAD parts is as easy as changing a board.

If you need to know--there is a seller I use on EBAY WITH THESE CHIPS.

These sets are not like the Plasma sets where they only sell circuit boards--with this kind of set you are almost always better to fix the board you have.

If you need any help do not hesitate to ask--I am here to help.

If this information helped you rate this solution as I do this here for free.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.



Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.

What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Converge problem on a kp-65ws500 sony rear proyection tv

You can download a copy of the service manual that explains how to enter service mode and perform convergence of the red/blue/green guns, but unless you are comfortable doing something like this, you may be better off calling a good shop familiar with rear projection sets and getting a quote to have a convergence service performed.

the convergence board has nothing to do with tuning of tv, the convergence board put three colour gun (red, green, blue) to work with each other, else you get three image, of red , green,  blue or mixture of all as seperate image, the convergence board for american tv and Australian tv is possibly the same what you check to see the board  part number is the same you possibly need to see if the convergence board has got the memory i.c. if that is the case, you need to tune you t.v reset the channel etc good luck.
need more help let me know.
