It sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel... replacing a new colour wheel will solve ur problem

Your TV most likely has a convergence 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 are some photos of convergence problems.

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 replacedred ghost image or shadow - 0667c5f.png common problem.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

WD 73835 has ghosting images during dark or red scenes

Make sure your contrast isn't set too high. Most ghosting is caused by either contrast, brightness or tint issues. Try adjusting these settings. Also check if there is a Dynamic contrast setting for your TV as well as this can cause ghosting also.

I have a Panasonic PT-53WX54J that will not Converge

you need to replace or have professional convergence amplifiiers. If know how to desolder and solder you could repair yourself or in home professional tv repairperson will cost you $275-$400. The convergence adjustments via remote are half the battle the IC's loose clarity over time.

Picture shadow on rear projection Sony big screen TV

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

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.

Perfect! That is typically called "Ghosting" where there is a faint image shadow behind the image on your screen. I'm glad you were able to get it fixed!
