Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

Yellow streaks on screen.

Our Hitachi 53UDX10B 53 inch set has developed stationary yellow streaks on the screen. Would cleaning the lens, screen and/or mirrors on this specific set solve the problem? Any ideas would be greatly appreciated.

My 53uwx10ba has developed a curved light streak across the screen near the top. Do you know how to fix this problem?

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 is mostly yellow and blue with double images

you have lost the convergence IC`s in your set, this really isn`t a diy repair unless you are very proficient in un-soldering and re-soldering components, once replaced there will be an alignment procedure as well that will require the service manual also, if you have more questions feel free to ask away, video-tek

TV wont stay on

Sounds like a short somewhere in there. I see old pre-HD big screen sets going for well under $200 on my local craigslist, so look there for a good replacement, because the repair will cost more.

Or fork over about $500 for a good used HD projection set.

Picture is yellow and green

Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
