    Did the V pos D Tweak. Works great! I press mute, then enter. All is ok. However when I restart the TV. Ghosting is back! I changed 30 ~ 31. But after a few minutes - turn on the TV. And it always goes back to 30!!! I did the tweak 10 times or more. always works!, but does not appear to save! (I do not press the mute and enter botton at the same time). Is there some knid of auto-correct feature I have to turn off or something? Any help would be Great. As a note: I am in Japan and my TV is called KL-50DX700 it seems to be similar to KP-60ws500. anyway, Sony service came and said I needed to change my LCD block etc... $700.00 or more they said! I started looking for a solution and found this tweak into the SM. Great! works great! Picture is fantastic again! But, please any help on permently saving!!!??? I would be very greatful!

    I too have the KF-50XBR800 and the ghosting problem. None of the image revision settings seem to fully correct the issue. Auto and "3" seem to be the best, but I can't make any changes to the V position as the other respondent mentions due to my source input being HD. Anyone else had success correcting the ghosting

    Same Sony TV, same problem. Auto works best but still there. 1-4 are worse. What is the "V pos" tweak?

This problem is a defect in the optics block. There is however an adjusment procedure to correct this problem. Please send me and email to and I will send you back the detailed alignment process on Monday.

I have a sony kf-50xbr800 that is 6 years old and i am getting a blurred image/ghost image that I can't correct. Changing the image revision setting to either auto or 3 helps a little but does not solve...

The image revision setting is designed to compensate for aging transistors on the optical block assembly.If adjusting it does not completely correct it you will have to replace the optical block.

Red ghosting on images that are not closeup

1. Power off -- let bulb cool.
2. Display - 5 - VOL+ - Power (in quick sequence) to display service menu.
3. Go into the user menu and set auto revision back to auto.
4. Put an image on the screen that shows the problem. I always found the edges of a 4:3 aspect ratio signal displayed the ghosting very well on my set.
5. Use 2 to scroll through the categories to find D GM TG
6. Use 1 to scroll through items in D GM TG to find V POS D
7. Write down current value.
9. Use 3 and 6 to change the value to minimize the ghosting. You should only need to move it up or down a value or two.
10. Press Mute - Enter to save the changes.
11. Power off and let the bulb cool.
