Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

I hae a Hitachi 53in, widescreen, on the screen it looks like the colors are seperating. Would this be the lenses, if so how do I recalibrate them? Thanks, Drew


That would be the convergence. This usually can be adjusted either through a menu or by adjusting controls inside the set. To do this properly, you need a signal generator to create a grid on the screen so the three colors are aligned with each other.

How do I aling colors: the red and blue colors are not align making the tv look distorted.


On my Hitachi there's a convergence button on the front panel. Press that button which will give you red & blue lines. You have to use your remote to converge (align) those lines to correct the picture. If the lines won't converge I've been told it could be a bad convergence IC & tech is needed to fix...could be approx $300 to fix.

We have a Hitachi 53udx10b tv. Recently it was


Projection sets have two very common problems.

The first common problem is convergence

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 Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant 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

Broken screens on 53'' Hitachi rear-projection TV


I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

The color blue gun has gone milky and I need to replace it. Is this a common problem?


For a television of this age it is common for the source to deteriorate due to heat.
Depending on the build and design it could be a blue light gun as in the old projection tv's, or if it is actually an LCD projection then the entire light element will need to be replaced.

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Colors are out of alignment


There is an alignment mode that you can get to. You must take off the back cover and look for the alignment switch I suggest that a tecnician do this because he has the propper tools and knowledge. If just an allignment is all it needs it should not cost that much. You have to try not to move this type of tv around because it is very sensitive and the slightest bumb can send it out of wach.
