Hitachi, Projection Color TV,C43-F550,C43-F550p,C50-F550p

I bought this tv in 2003 and never used it or remove it from the original box untill October 2007. Tv will no come on except for a short click. I called a Tech to look at it. It was found that some rats got into the Box and ate up some tiny(chocolet,brown,blue green) wires inside the tv. Also the resistors look like they were dry. What is the best way to tackle this problem? Shoul I replace the system board at once? Help ,Fellows.

What do you mean when you say resistors look like they were dry??

did you try fixing the wires? i would do that first and see if anything else is bad.

Hitachi TV, has red ghost lines outlining image on screen! Help!


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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 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 need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

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.

Magic focus


This might also be called digital array. You might have to do the manual adjustment with the cross hairs on the screen. These, one red, one blue, one green, should all align on top of each other in a white color. If this does not work, you should call 1-800-448-2244 for assistance in finding a local service center.
