Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

The Model# is 53UWX10ba - Colors off in upper left part of screen

Hi, I think I have the same problems as the other two people. I'm watching TV one day and all is well, then the next day I notice that the colors in the upper left part of the screen is mostly yellow (bow like). Pushed the magic focus button and as you watched the screens the blue was extremely bowed and shifted in the middle on the screen. After the magic focus completed it was WORSE than before. I tried a 2nd and 3rd time then gave up, not change for the better and as luck would have it my extended warranty JUST expired April. HELP!!!

    Hi Dan, solder??? I don't think I can do that. What does it take to change the ICs? and where/how would I find these parts inside the unit. I'm trying to get my hands on the service manual for the tv which I'm sure would be helpful.

    Enough said, I will not be experimenting! Thanks for all your help.

The problem is with the convergence circuit. If you can solder, try resoldering the pins on the convrgence ICs. If that fails to resolve the problem, replace the ICs. These ICs will be large and black, attached to a heatsink and be marked STKxxx.

Update this with your progress.

    If you can not solder, you will not be able to repair this yourself. These ICs are very large and are obvious once hte set is opened up. The heat sink alone is the largest silver part inside the set. There are high voltages inside these sets even when unplugged. If you have no experience with these, DO NOT experiment. The typical parts cost should be between $25-$50. Add in the local labor rate for the total repair cost.

Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Hi, Your tv model has a small light blue color button inside for manual adjustmnet mode. You will have to remove the front covering below the screen. its just attached with velcrow. Then there will be a centre wooden pannel with the the switching box screwed to tv front with around six screws.Open this panel and look to the left corner of the chasis boards in front of a small metallic box.

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

Good Day;

When you activate the Mj focus the TV is restoring the data from the TV's digital circuits. So, you have the ability to change the IC's you can do this.

You need to go into the con service mode. Take off the front grill, remove panel, 6 - 8 screws. From the front there is a switch on the left hand side, it is small, white button with TV on. now you are in the service mode, using TV's remote adjust. Make sure you save dat. Go hit on line site get more info.

Goo0d Luck!
