Hitachi 53UWX10B Projection TV - Color Separation

From what I understand, the problem I am having with the color separation on my TV, it has something to do with IC and STK. From what I've read, a TV repair expert must fix it due to welding issues and alignment issues. It first started in the upper left corner of the screen with a blue outlined loop down into the screen. Now, it has progressed much further down the screen and all colors are misaligned. Is it true that we cannot fix this ourselves? And is there something else it could be, or is this a pretty standard problem.

Convergence settings on hitachi 53uwx10b


Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • 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.

Picture is clear but with a yellow tint .


Make sure, if your using component cables ,that they match up color for color and are plugged in.If it looks good try adjusting your colors on the TV.You can also try unplugging the TV for 5 min. and then plug it back in.This might be a TV issue.

Hitachi projection hdtv has 3d effect and bowed shape


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 overs.

Color convergence problem


I'd suggest either replacing the ICs and resistors on the convergence board (requires soldering skill by yourself, someone else or an electronics repair shop) or purchasing a new convergence board from Partstore for $299 and swapping it out yourself.
While it may sound daunting, it really isn't once you find out more regarding this issue and dig into it a bit.  There's a wealth of info at the Digital Home Forum regarding this particular issue and ways to resolve it.
Good luck...  -TD
