My pictures do not align and there are three different colours of pictures; red blue and green. The flash focus doesn't work either...how do i fix this? thanks

Hello
If you see the picture in yellow colour, means that there is no blue colour output from the video drive section in your tv, Yello is the mixtrure colour of red and green. Green is actualy there. blue colour is absent.
To detect this fault, you must open your tv. Just look in to the video output section, can be located at the picture tube base card, which is plughed into it diretly. See for any loose soldering points there. Check whether transisotors are used for red, green and blue output stages, or an Ic or three seperate Ics are used for this purpose. Anyway, blue catode of your picture tube pin gets a hig voltage, and so the blue emission is absent. You just check the voltages at red,gree and blue catodes, at the respective picture tube pins, which can be taken at picture tube base card. All of these three pin voltages must be somewhat equal to each other. In your case, no voltage at blue cathode will be higher that the other two. Check for the reason. It may be due to an open video output transistor [blue], or an Ic, of one Ic if used for the three colour outputs. Check and replace the same, will rectify your problem. Ok

Sounds like a convergence failure, here is a tutorial I made:

Let me know if I can be of further assistance.

Ur tv convergence are dead.U know how to solders?Must replaced the 2 STK convergence ICS,some or all it resistors.Tries Websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

Count the # of flashes...call Samsung tech support

Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

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.

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 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. And you should be able to get the grid straight.

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 fix

Replace the convergence I.C.'s STK392-040. its the two big black IC's when you open up the back of tv.

So this is a rear projection TV.

Chances are the tubes are out of alignment. When cleaning or anything never move the tubes as it will be hell to get em back properly.

In the back you can take off the rear panel and move the tubes to partially re-align the picture.

This is generally followed by a model specific procedure using the remote to bring up alignment grids to finalize the picture alignment.

The reason for the 3 colours in the picture are that the rear projection units use Red, Green and Blue tubes to create the one colour picture.

All in all... When I messed mine up it took about 2 hours to set it straight again.

Now I just have to fix my flashing screen problem and i'm set.

your convergence amp ic's./if you want to cheat/align the other two colors and manualy move the green yoke rings on the green picture tube neck so the green cross aligns with the red and blue.,they shuold form white when all three are aligned,on top of each other.

Hi there my t.v has a similar problem, I turned it on and the colours arn't right, there the colours go out in three circles mainly mainly blue, green, red yellow, but depends whats showing on the t.v? Please help.
