Most of the time when you have ghosting problems it is a bad connection on you cable connectors make sure they are tight or maybe they are bad. Interferance causes that or even capacitor in tv or even a bad cable box . I gave you a list of all things that cause it but i think its connections.


I hope this helps DOCTOR VIDEO

THE PICTURE IS GHOSTING AT THE TOP & BOTTOM OF THE SCREEN. THERE


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Model 50UX58K - picture has distortion & shadow on right side of screen


Hi, if the shadow is colored lines then you probably need the convergence ICs and possible reisitors near them replaced .
If the shadows is just like a ghost of the image or a bar from top to bottom, then check if it does it on every input (dvd for example) , there are blanking bars that you can't see past the edges of the picture and when you have a bad cable signal you can see the ghost of the blanking bar sometimes. if it does it does not show the shadow when watching a DVD then its a signal issue with your cable/satelitte .
If your convergence is the issue, try the adjustments first and if that doesn't correct it, you can replace the ICs using kit # x480293 or stk392-110 (2 ICs) soldered in very technical for even a technician.
repairman cost about $250-$350
hope this helps

Shadowing


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.

Big screen showing double and red ghost color


Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.

50" rear projection sony HDtv and ghosting when using my ps3


To bring up the "service" menu, put the TV in standby mode, then press in sequence :

Onscreen Display ( the little screen with the i+ in it )
5 ( channel number 5 )
Volume Up ( upper end of volume button )
Analogue ( middle top button )

The TV should switch on and when it's warmed up, you should see a screen with lots of big green lettering on it.

Press the "menu" button ( middle bottom )

Use the direction dial to move down to "LCD Drivers" and press right on the dial to enter this menu.

Move down to "S H Pos Reg R". It should be "10", change it to "11". ( Left/Right to adjust )
Move down to "S H Pos Reg G". It should be "10", change it to "11".
Move down to "SHPos Reg B". It should be "10", change it to "11".

Press the menu bottom to drop out of the menus, and the standy button to drop to standby. Switch back on, and hopefully your ghosting will be gone.
