Hitachi Picture Looks Like 3-D or Ghost...

HELLO, I BOUGHT MY PROJECTION TV ABOUT 5 YEARS AGO. I'VE NEVER HAD A PROBLEM WITH IT...UNTIL YESTURDAY. THE PICTURE IS STILL THERE AND THE SOUND IS THERE. THE PROBLEM IS THAT IT LOOKS LIKE A 3-D MOVIE OR A GHOST IS BEHIND EVERYTHING. I SPOKE TO A TECH ON THE PHONE AND THE PERSON SAID IT WAS A BULB. ALSO, IT WAS GOING TO COST $475.00 FOR PARTS AND LABOR ON TOP OF THAT $100.00 JUST COME OUT TO LOOK AT IT. MY QUESTION IS CAN WE FIX IT OURSELFS? AND HOW MUCH DOSE THAT PART ACTUALLY COST?

    I FORGOT TO MENTION THE MODEL IS 43FDX20B...OUR LUCK HAS BEEN NOT VERY GOOD. SO ANY ADVISE WOULD BE GREATLY APPRECIATED.

    Ok, so if it's the convergence how do I replace it myself?

  • Anonymous Nov 04, 2007

    The Hitachi 43FDX20B has it's own crosshatch generator. See Keohi HDTV for more details on convergence alignment.

    Boy that's a link and a half.



    Anyhoo, I have some soldering experience and a small amount of equipent. The Convergence ICs could be replaced if I could find a schematic somewhere?



    Any ideas?



    I would also like to confirm the symptoms. My red does not produce a "square" crosshatch pattern, instead the left side of the screen appears arched to the center with the top lines dropping down and the bottom lines arching up. Is that definitely the convergence ICs or should I look for other issues?



    I've already tried magic focus and manual convergence but there does not appear to be any way to adjust the pattern.



    Thanks for your time and help.



    Mike

If you have any solid state repair experience and know how to solder, then all you need to do is get the convergence ICs and replace them. Then the set may need to be alighned a bit. You will most likly need a cross hatch generator for that. Yea that price is a bit steep, but it will end up costing you more in the long run, if you mess up the board while soldering or adjusting the set, and after getting the parts and equipment. I would highly advise you to get another estamate for this repair. Good Luck Please do not forget to rate this thread.

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.

GOOD DAY ND GOOD LUCK;

TRY THIS, IT WILL CORRECT CONCERN:

50V500 ONLY
GHOST: May be described as "Out of Convergence" but ghost is still attached to main image.
CONDITION:
A "ghost image" appearing to the left or right of images in the picture. Can be varying shades of a primary color (red, green, or blue) as well as gray. Can easily be seen in the 4 x 3 mode, at the edges of the picture.
CORRECTION:

To correct the problem, please do as follows:
  1. Access I2C Menu. (See page 57 of the Service Manual).
  1. To enter the I2C Service Menu, with power off, (on the front control panel) press and hold the INPUT button. Then press the POWER button for two seconds. The following Service Menu will appear.
03b_ghost_image01.gif Figure 1
  1. BEFORE CONTINUING: CONFIRM THAT THE R, G and B DRIVE ARE SET AT 40.
  • Be sure to press SELECT after each change to SAVE the new Data.


  1. Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
03b_ghost_image02.gif Figure 2
  1. Move the joy stick to the right to cursor right once. The next page will appear with the word GHOST highlighted.
  2. Cursor right again, and a white screen will appear with a BLACK SQUARE in the center, as in Figure 3. You will see LCD ADJUST, followed by “SHP” and a number (value).
03b_ghost_image03.gif
Figure 3

  1. If the unit is out of adjustment, you will see a gray ghost on either side of the black square. Move the joystick to the right or to the left until the ghost disappears. The number values will change up or down.
    • If the ghost adjustment is off with a lower value, there will be a ghost to the left of the square.
    • If the ghost adjustment is off with a higher value, there will be a ghost to the right of the square.
  2. Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
  3. Press the "EXIT" button three times to return to normal picture.
  4. Adjustment is completed
  5. I HOPE THIS WAS HELPFUL, big IRISH.
