Hitachi 43FDX20B As of this morning our TV has developed a blue ghost. We tried the magic focus but it did not solve the problem. Any suggestions? My husband is very handy and used to repair small appliances so he may be able to follow your suggestions

My husband rolled the tv up the street from our neighbors.. it has yellow and green ghosting. tried the magic focus did not fix the problem with the guns.. any advice would help thanks,...


You have defective IC's in the convergence circuit. Part number is STK392-110, it requires two of these chips and standard price from a servicer should be around $350 for all.

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.

if this tv is older than 5 years it may need to refill the liquid on the proyection bulbs and/or could have contaminats in the fluid causing the ghost and to fix that you will need a professional person to do it

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.

Ghosting


Hi,
This sound like a convergence problem and maybe another problem for the pink symptom. I would not suggest to do it yourself on this one because after the IC's are put in and sometimes a resistor or two there is also a very extensive alignment that could occur. Just off the cuff have you pressed the magic focus button on the front? If magic focus don't fix then the convergence is bad . Suggest a good tv repairman.

Loss of color picture


I have a blue-ish yellow ghost tint which just appeared on my 51" 51SWX20B made July 2002. Did the magic focus got a number 5 at the end. Did you get a number when you did the magic focus?
