This is a model first sold in 2002---if it is 3d it means one of the two convergence chips (IC's) is bad.

This set uses 2 of the STK-392-110 chips--they and any protect resistors around them that are bad need to be replaced and the set adjusted with the Hitachi remote.

I do not know if you can do this repair--consider that you can buy the pair of chips and any parts needed for less than 20 dollars--most shops charge 300-400 for this kind of repair...


Do you know how to solder if I tell you how to get at the parts etc?

Magic focus will not work if either of the chips is bad. After the set is repaired it will not have this problem again for 5-8 years---normal life span on these parts.

Let me know if you need help or advice--I am here to help people---


Regards, SD TECH

Double image and 3d color

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

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors

sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

Double image on green

Focus won't help if it is a double image. Sounds like convergence amps need to be replaced. Very typical on these.

53UDX10B 53 in. Rear Projection "3D vision"

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
