Question about Hitachi 53SWX10B 53" Rear Projection Television

2 Answers

Color is warped and wrong

Hello, I know next to nothing in terms of TV tech. Today I saw this Hitachi 53SWX10B in a driveway with a sign saying it was free. I talked to the owners and they said it just needed a part, and if I knew someone who can fix TVs I would be set. So I took it and now am trying to do some homework before I go to a local repair shop. It appears in good condition, sound is good, and picture is better than I was expecting being that they were just giving it away. The first pic is the Hitachi, the second is another TV showing the same screen, showing how it should look.

I would greatly appreciate: A) if someone can tell what is wrong with the TV from the pic, and/or B) what I should expect to pay for quality repair. Anything you think I would benefit from knowing, I would also appreciate. Thanks much!

Your TV has a convergence problem. Here are some of the most common symptoms.

  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in or warped.

Here is a quick test....

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

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

A convergence amp has failed. Very common. Plan on just replacing both STK modules (big flat circuit modules mounted on a big heat sink) with upgraded parts. Good ones cost about $40 each. Then readjust the convergence. Total cost at a shop is $250-$400.
Hope Ya Fix It.

I have a Hitachi 53swx10b. The sound is starting to go out. It will work and then goes silent. I turn the tv off and back on and it will work. What is the easy fix?

There is not an easy fix for this problem with this model.

This set uses a surround sound audio board that processes all audio. Our shop no longer repairs the boards as it can be very time consuming and usually we send the board out to a national company for rebuild.

Problem is solder connections on tiny flat pack parts on both sides of the board break and I saw several where set was only months old, at that time Hitachi sold the board but it is no longer available from them

The Rebuilders (last time I used them) charged about 200 including shipping as you have to remove the board and send it in. Removal of the board is not hard and I can tell you where to look for it.

Sorry if this is bad news but it is what your problem is.

Let me know if you have questions as I am here to help.

Color on Panasonic 2004 is off and appears to be warped

It sounds like a convergence problem; most of these sets use two convergence IC chips that both need to be replaced; usually this can be done right in your home.
