5005 picture change?

How has the lastest ES5 firmware --apeared to everyone now?
For my 5005 I have changed the solder connections on my Television from 60/40 rosin core solder to 4 percent silver solder and it has made a very noticable difference in the picture even with very cheap cable. I may try it on the liteon–I’ll keep you posted!! Hell I may even try it on the liteon with 7 percent silver solder. By the way I have a USA machine I would like to know if it helps anyone elsewhere… More hints later --I’ve got real work to do now.
Bye.

also has anyone who opened the liteon machine found any cold solder joints or locations where there is very very little solder. Tell me if you do. Thanks.
