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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - 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.

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 CONVERGENCE SOLUTION

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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from

Hitachi 50UX11K wavy pic rolls


Sounds like the vertical controll circuit, it could just be a capicator that is on that circuit. as per the comb filter its very difficult to repair as the capacitors are micro and difficult to solder unless your soldering skills is very good. The is a place that repairs these comb filters www.ptscorp.com i am not sure at what cost though. At any case you can bypass the comb filter by
1.) getting an s-video adapter for your vcr
2.) connect the vcr to the tv using the s-video adapter
3.) change the channels using your vcr.

I'd rcommend you get a professional to have a look at it and repair it as it is much to difficult to repair your self even if you have the service manual

Since the comb filter is discontinued is will be best to bypass it by using the S-video input especially if you are on satellite receiver or use a composite to S-video adapter if you don't have dish. You might get the adapter at Radio Shack or shop online at Circuit City or Best Buy

Hitachi C50-FD2000 Screen Distorted


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. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.
