Picture Problems with Hitachi 53" Projection TV

We have a Hitachi 53UWX10BA Projection Tv purchased in 2002. It has developed a yellow semi circle in the upper left corner of the picture with a blue outline around it. When a sports channel is on with scrolling scores at top it makes another line in the yellow and blue below the real line of scores. We have tried the magic focus and it does nothing. We also are have trouble with the power light staying on when we turn TV off. We have NO one in our area that works on Hitachi TVS. HELP. Thank you for your time.

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.

53UWX10B Red giving problems

Good Day,

Welcome to the world of having a convergence circuit problem. There two things you can do; get it repaired by a Factory Authorized Service Center or repair it your self. Purchase KIT 10 from B&D Enterprises, 1-800-458-6053. The kit has everything you will need except soldering equipment and experience. Good Luck, big IRISH.

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...

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 - 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
