Okay here is a simple guide on how to do this fix. You do it at your own risk.
1. You need to reset the pulse meter in the service menu.
There are several methods to get into the service menu, the easiest being with a GGF1589 or GGF1633 service remote. If you do not have a service remote then you need to get in by sending a command to your TV's RS232 port. There is no other way.
See my original guide on how to do this: http://www.avsforum.com/avs-vb/showt...5#post21295335
If you need the service manual for your particular TV get it here: http://elektrotanya.com/?q=keres
. The download link is hard to spot but it is at the bottom right next to the image of the manual. It takes a few seconds to appear but it will say "Get Manual, Not logged in Only 2 downloads allowed a day".
Once you have entered service mode, you can use your existing remote to navigate to the pulse reset option in the etc+ node of the service menu. See the following: http://www.avsforum.com/avs-vb/showt...5#post21298105http://www.avsforum.com/avs-vb/showt...5#post21295335
2. So now you have reset the pulse meter now what?
You should immediately see that the red tint has gone, good.
Watch some TV to check for any issues. I didn't have calibration equipment so used my eyes to judge. I didn't see any issues or problems.
Watch a wide screen movie with black bars for a few minutes and then quickly switch it to full screen (zoom will work). If you notice the blacks stick around for a few seconds (they kind of melt away) then increase VOL RST P (under the PANEL FACTORY node of the service menu) until it stops. Mine went from 23 originally to 62 after adjustment.
That's it. There are some who suggest that color balance may be slightly off but I couldn't see it. Calibrate to be sure.
