Re: Half the screen has ghost image (not focused)
Replace the convergence ICs. They are located on a large aluminum heat sink withSTK numbers stamped on them. They cost about 10.00 each. They have to be soldered in. Let me know if you need anything further.

Line, faults & possible causes to both Plasma & LCD screen are given with illustrations. You can get an idea about the fault to an extent.
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.
Replace the convergence amps and test and replace any or all of the 2.2ohm resistors in the yoke return path out in front of the amps. This unit takes two STK392-110 Sanyo originals, DO NOT GET CHINESE KNOCK-OFFS... Buy them from Acme sales out of Florida and you can be assured they're originals.

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 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.
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.
Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
Move the joy stick to the right to cursor right once.The next page will appear with the word GHOST highlighted.
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).
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.

Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
