Shadows around the objects

Suddenly the elements in the display appear with a sort of ghost or shadow like a duplicate that is superimposed slightly to the right of each icon and its respective text.

One common cause of ghosting is an inferior monitor cable. Remove any extension cables and check again. The monitor may be getting interference from another device nearby, such as a printer, for example. Try turning off/ disconnecting other devices and see if the ghosting disappears. If so, you could buy a better shielded cable, or rearrange your components to prevent the interference.
That would be a simple fix if it works....

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

This may help...SIMPLE ! The "shadowing" you talk about is due to cables in back of your computer, touching or too close together. I had this happen to mine. I moved the cables apart, and no more shadows !! Sounds too easy, but it works. Takes a few seconds. Immediate results.

Picture has ghost shadows in the faces of people mainly news anchors. Light colors like whites and oranges also have shadows. What could be causing this?


If it does not really display this when a DVD etc is played via a rear audio/video input it is not the set.

Modern cable or sat signals often are compressed and sets cannot on close up views keep up with the signal--when signal is compressed it causes this kind of issue--no way around it.

Akai PT5598HDI Rear Screen Projection TV With Blue Shadowing


If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

Duplicate image in pink displays on the screen.


From your description, it sounds like an alignment problem. There are 3 LCD panels in the projector. Each one displays an exact duplicate image of the others except it's either red, green, or blue. Under normal conditions, the images precisely overlay one another so you get a sharp image. Due to age, heat, or vibration/shock(impact) it would appear that the red LCD panel has shifted a little, giving the "ghosting" effect. You'll have to have the unit repaired by a qualified tech. He'll have the special electronic equipment needed to align the panels properly. Before sending the unit in, try a reset in the menu. Sometimes, the projectors can shift the image electronically, using math algorithms which will try to auto-sharpen the display. Hope I was able to help!---Rick

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.
