Colors on the screen are messed up with ghost HITACHI


Its not clear what kind of tv you have but it appears to be older rear projection tv with three picture tube. This problem does occur due to the convergence board going bad. Needs professional help to repair unless you know a lot about soldering ICs. Check out at www.fixurtvs.com for more answers on this problem, repairs and costs.

HITACHI 57UWX20B has blue ghost shadows how do I


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 TvRepairKits.com 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.

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Hitachi with blue out of focus or ghost imaging and have tried magic focus many times!


Good Day,
When you turn down the BLUE the TV will give a yellowish picture. That is why the TV has three CRT's, it needs all three colors. The problem most likely lies in the TV's Convergence Circuit. To repair yourself get KIT 10 @ 1-800-458-6053 or www. bdent.com. If not call a Factory Authorized Service Center and have them give a written estimate, avg cost $550.00.
good Luck, big IRISH.

Hitachi 43FDX11B television Ghosting


I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.
