How Do I Do An Image Revision Tweak On My Sony KF-50XBR800

Greetings

1/4 keys scroll

2/5 keys scroll by category

3/6 keys change parameter values

Putting bullets in the hands of children ... who already have the guns.

Nothing I've read in this forum would suggest your problem is related to the bulb. You've probably already seen UMR's most recent comments on this -- and that most every GW II needs this tweak at some point.

If you are careful, everything should be fine. The issue is that if you accidently change another setting, save it, and don't know what you did, plan on calling your friendly ISF calibrater to fix it for you.

Here is what I did to mine:

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.

Done!

I don't know if would matter, but I used a paused SD image (sized to 4:3) from my DVR. My set showed the ghosting most on the screen edges and on the edge of skin tone areas. So I used a scene that displayed the effect in those areas. I never got it perfect on the edges. But the actual screen image is good.

I never bothered to program the "Freeze" key into my universal remote. I had forgotten that it existed.

Happy to help, topcat84. Enjoy your new bulb!

Is this something he will have to continue adjusting down until he can't adjust anymore?

I've never read about anyone having to adjust it more than once. I know I haven't had to adjust again.

I know this an old post, but I just wanted to say THANK YOU!!! to RobbinMerritt for the walk-through. This problem has been driving me nuts to say the least. With IR on Auto there's a huge shadow, even on 3 it was very noticable.

This fixed it!! Thanks for saving my $4,ooo 'investment'!

thanks you so much. i ve had ghosting for over a year..and i fixed it in less than 15 minutes. thanks

100% improvement with this one simple change:
Category - D GM TG
Item - V POS D
Old - 30
New - 31

Thanks!

It's nice to know there are still some GWII owners out there. Not many posts on that TV these days.

hi

new to this place, but i have the 4yr old rear projection lcd, 60 in and ever since i plugged in my new ht pc, all i notice is the ghosting....

i'm gonna try that little bit and save myself $4000 on a new sharp

Thank you, thank you, thank you!

RobbinMerritt you have just added years to my life!

Hello to all,

I've been reading the forum since I bought a used Sony KF-50XBR800. I also noticed reddish shadow on face images and 0.5inch wide shadow when CC is on. So, I tried the revision treak but it's still there. Any help will be greatly appreciated.

FYI, the bulb hours indicate 13K+ hrs.

Current DVD player (which I bought together with TV) is HDMI and the cable used is HDMI cable with DVI connecting adapter.

Thanks

Thanks guys for the tips - I have managed to repair the ghost effect on my TV buy after I while the settings returned to normal - with the ghost effect - I don't know why but the TV remembers the setting only for a limited time.

Any ideas how to save the settings for ever. I have pressed the [mute] many time and it aways shows SAVING and than it is ok - but after time when the TV is off it returns to 30 with ghost effect.

The save sequence is the "mute" key followed by the "enter" key.

thanks a lot man - I didn't notice the [Enter] key in your previous post - thanks again.

I've done this. It is indeed a great way to fix this set. Thanks to all who posted, and especially to UMR who's tweaks have given me years of enjoyment from the KDF-60XBR800.

I also found a new "fix," for the image revision problem, and my KDS-R70XBR2 will be arriving next weekend. Though, realistically, this was prompted more by the addition of a PS3 to my home theater line up, and wanting both the additional size and better black levels of the new set.

yes, I applied this "fix" several months ago myself. And I had my XBR2 calibrated by UMR so my high quality experience continues!

Just had to do this to my almost 4 year old KF-50XBR800

The picture is perfect now! Thanks so much!

Hey guys,

I did this fix as well, I had a bad ghost shadow to the *left* of objects and the above fix worked like a charm.

For the most part it's gone, except when I put my Xbox in 720p, then there is a bad ghost shadow to the *right* of objects, and none of the "Category: D GM TG" adjustments made a difference.

Any ideas?

Does changing the Image Revision setting in the User Menu have any effect?

Just tried, no go.. still massive ghosting to the right.. I can take a pic if need be.

I've nothing further. Sorry.

Ah thanks for trying.. I can only really notice it on 720p..

I have ordered a new bulb (it's due), do you think that could possibly help?

I know at least one owner had to undo the service menu change after changing his lamp, so I suppose anything's possible.

You might try posting your question over in the original "UMR does GWII" thread. Perhaps UMR still has a subscription to the thread and would comment.
