Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

Hitachi projection 53" screen color off

The picture shows yellow shadows to the sides of the images and no longer has true color. There was a mention of bulbs needing to be replaced. Could this be what is causing it? We have a Hitachi HDTV Ultravision digital model #53UDX10B V1G005239. If it is a bulb is it possible to fix it ourselves, my husband is electronically knowledgable? If we can't fix it ourselves, what kind of cost are we looking at?
Thank you for your help

Since this is a CRT based projection set, there is no "lamp" involved. Does the picture look like 3-D? If so, the problem is likely to be a convergence problem. There should be 1 or 2 convergence ICs marked STK392-110 inside attached to a heatsink. If you can solder, try resoldering the pins on those ICs. If that fails to resolve the problem, replace them.

Keep us posted.

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

Yellow vertical bar on right edge of screen


Your set is starting to get a convergence problem and the only way to repair it is by changing the convergence IC's,(3)one for each color,the blue migh be showing more now but soon all 3 colors will be out of alignment and you will not be able to correct it with the custumer controls,is great that it has worked for so long without this problem,if you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for help from a pro-servicer.Let Us know how it goes.
