Auto convergence not working 142cm LG rptv

You have an issue with the convergence board possibly a blown transistor in the blue control or the defaults for the auto convergence needs to be reset.

What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Tv have a convergence problems,it dead.Tv convergence board is dead.Require changing the 2 STK convergence ICS and some or all it resistors.To solved the tv convergence problems.Tries Websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergencce kit.To replaced those convergence parts on the board.

Well this is the fix for the usual Ghosting problem....

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 hope this works davy mac

You may have to clean the crt's and lenses and the mirror. Unit may need total convergence from the service menu. If image is blurred in only one area like the corner I would suggest NOT to adjust the electrical or mechanical focus.

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.
   

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.
   

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.
