Hi.

The 2 convergence ICs will need replacing.
Providing you have got soldering iron with no bigger than 1,2mm tip desoldering braid & heat sink compound you can do it your self.
The convergence ICs are mounted on 2 x large aluminium heat sinks with fins on, The ICs will have STK 392 **** stamped on them.

52inch projection screen television has only red and green colors and its difficult to see the picture.


If the picture looks 3d with lines bowed it may be a convergence problem---go into the customer menu and call up convergence and at least look.

There is red and blue lines around screen and images. (Almost looks like it should be 3d). Does this mean it needs a new lamp/bulb? It is only 6 years old. What is the cost for the part? Thank you


If model number is as listed (46f500) it does not use a lamp or bulb but has three picture tubes.

3d means the two convergence chips in the set have failed.

It depends on if you can solder etc, not a very expensive parts cost (under 30 dollars)

Can you solder?

Picture looks like 3d i have ajusted screen but keeps going back to 3d and picture is bowed


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

Picture is double lined of greens and reds


You have a convergence output IC failure. You my also need a few small associated parts as well. Expect to pay $350-450 to have this fixed.

I would check the CRT socket module for Cracked solder joints. If not you may be in the early stages of the CRT shorting, If so you will need a new CRT.

Red green and blue lines


Most projection TVs have an option to refocus. For example, my Sony rear projection TV has a button on the front for focusing the lamps. Try finding this button or option in the menus with your remote. Projection TVs actually use three lamps, one red, one green and one blue. These need to line up exactly in order to form a good picture, and when they come out of focus, you see the edges which sometimes has the effect of a 3D image when you aren't wearing 3D glasses. Hope this helps!
