Question about Hitachi 50UX57B 50" Rear Projection Television

1 Answer

Blue digital array



My tv was working fine and then there was a click and the blue digital array went off and when I try to fix it it won't move and now I have this swoop on the top of the screen which is very annoying as you can see in the pics. Is there a way I could fix this alone or have someone do it for me? What happened? The red works fine but most of the blue won't move up or down. The Tv is about 5 years old and we never had a problem until now. Is this fixable or is it time to buy a new tv?

Blue shadow around picture. tried digital array blue won't converge. red and green work


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Colors do not line up on my tv ( left side of sreen looks like 3D) digital array "+" are only white on right side.


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

Blue won't line up at the top in digital array


you need to replace both convergence ICs and the six 1 watt feed resistors. The ICs are both STK392-110 and the resistors you need one of each RK42 3.3 ohm 1watt, RK46 1.8 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt and RK62 2.2 ohm 1 watt.
You can get replacement ICs and resistors at the following link with free instalation instructions.

Green and magenta colors offset in picture


Sounds like convergence problems, set may have been moved lately and this can cause it. Did you try Magic Focus when the set was warm or did you try it when you just turn on? Set needs to be warm, before you try it. If nothing works you will need convergence kit

Digital Array?


Replace IK04 and IK05, both STK392-110, but use instead STK392-150's for greater reliability. And don't get some Chineese knock-offs - use original Sanyo replacements. If you don't know where to get those try ACME Enterprises in Florida,

Also measure the low ohm feed resistors in that circuit. However usually just replacing the convergence amps will restore normal video...
