Question about Hitachi 53SWX10B 53" Rear Projection Television

1 Answer

Thin Red Lines Everywhere

My tv all of a sudden started to show thin red lines protruding from the right off all objects in an outline form. It is very apparent when utilizing the menu screen of the digital cable. It is not the cable itself as the problem persists on different video inputs with the dvd player as well. Any solutions?

    I have tried the magic focus and it will allow me to alter the other 2 colors but not red. Red seems to be truely out of whack and I'm pretty clueless when it comes to circuit boards, sodering, and anything else when it comes to fixing a tv. Any idea of the costs to have a tech out to fix the problem? Obviously the tv is a little large to be putting in the backseat and taking to the shop. Just trying to get an idea of what the problem is and a cost to repair as I am concerned a tech will try to upsell me and charge me much more than I need to pay. Thanks for any advice you can give.

So it's no longer under warranty.... right? The problem you describe is control by a 'digital' driver IC (integrated circuit chip) which has apparently developed temperature problems.

Red bowed horizontal lines

Projection sets have two very common problems outlined below.

The first common problem is convergence

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.

You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

My 61 inch RCA HDTV shows a redish shadow outlining each object


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.



Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Red outlines in the picture

somewhere in the tv menu there is a place to make video adjustments. one should be for aligning the color guns. one is for red and the other two are green and blue. it will give you a cross in the center of the screen. it should also give you prompts to adjust the lines for centering and to save changes. this happens eventually on all rear projection tv sets.
