Tri coloured ghosting

I have been given an LG Rear Proj TV model PT53a83t The right side of the image is sharp and clean but the left side has a ghost less than 1/4 inch wide of red/yelly/blue. Would this be fixed by auto colour aligning as per the user manual

    Hi,

    I have the same problem with my tv. I have tried going into the menu > convergence, the blue cross wont completely line up, any ideas as to how to correct it please. We have had this tv for 6 years & it's the 1st thing to go wrong with it. We have just shifted house & I think that's when something happened to the colour.

    Thanks

    Sarah

Hp 5550 patchy print


Most of the cases fuser assembly or supplies are causes of ghost image. If image is not properly transferring on media causes transfer roller or ETB.
Do this small exercise: Give print command, wait till paper grabs, once paper entered in cartridge area, power it off, open top & front cover, remove paper and see the print quality.Observed any ghost image what you observed? No ghost image? then problem with fuser assembly..

1.Remove fuser assembly, check any toner particles deposited on surface of fuser transfer roller or heater roller.. if found clean carefully with good cotton cloth while fuser having certain temperature,pl avoid metal & sharp objects to clean..
2. Clean paper path roller(You can observe the rollers to push the paper to reach the destination)
I hope this exercise will resolves the issue..

My LG rear projection TV RE40NZ60RB colour is ghosting with three colours separating. Colour converging does not rectify


There is a problem with the convergence circuit. It can be as simple as poor solder connections at the pins of the convergence IC or a defective IC. If you can solder, you can fix this yourself. Please confirm the model number of hte set and I'll provide the part numbers etc. required to resolve this.

Thanks,
Dan

Red horizontal lines on the screen


do these appear around the images on the screen? look like a horizontal ghost around the image. if so you have lost horiz.convergence on the red. you might try a auto convergence setup in the menu on most rear proj. tv's if this dosent work then you need to try and find a shop.

Red Ghost


This may be a convergence issue but it is difficult to determine with that description. Watch this video and see if it will help you determine if you have a convergence problem or possible something else.

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).

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.
