Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Hitachi 53UWX10B Hi. I saw a technician pop up a white grid on my screen with a black background and align the 3 colors up to the white lines on the grid. How do I get into this setting? If I recall, i think he used the Tv's remote to do this. Thank you.

Yes he used the service menu, however if you dont have the service manual I wouldnt recommend doing that as you can change the wrong item and your set can get messed up bad enough where you will need to have it serviced professionally. If youd like the service manuual go to this link they have one they will email you and they will provide free tech support with the service manual purchase

My hitachi 53udx10b was supposedly just serviced but the picture is extremely blue. Have tried adjusting picture to no avail. Help.


I am going to tell you a simple thing to do to know what your problem may be.

With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?

If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)

I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.

The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.

This is called gray scale; picture with color off has to be gray or black and white.

Before you rate this solution if you have questions make a comment right here and I will advise you.

HITACHI ULTRAVISON REAR PROJECTION TV HAS 3 OF EVERYTHING. IS IT WORTH FIXING?


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Hitachi 53uwx10b Convergence Grid Tilted A Little...


If the tilt is not that bad, I would leave it be. The reason is yes you can straighten the tilt out, but it requires a mechanical alignment to all 3 CRT's then you will have to align the convergence on all 3 as well. Please take a few moments to rate my answer. Thank you.

This is a convergence problem that can be as simple as poor solder connections on the pins of the convergence ICs or defective ICs. If you wish to attemp the repair yourself, please let me know and I'll look up the parts and provide additional details and instructions.

Hitachi 53uwx10b Convergence


The grid (called an overlay) is put in place to fine-tune one of the colors, usually green. Once one color is adjusted perfectly, the other 2 colors are adjusted to match the first color. For example, if the convergence data is completely erased, the tech will set up the overlay and align the green using to the overlay, and then align the red to the green and then the blue to the green. If the alignment is being done after replacing the convergence IC's because one or 2 colors are slightly off in the corners, the green is usually very close to perfect and the use of the overlay is not absolutely necessary. It is pretty easy to align one color using the outer edges of the screen itself. If you do need the overlay it can be purchased from any Hitachi parts distributor such as Herman Panson, Fox or Union Electronics.
