Thought I might post my story regarding my Kuro.
I have a LX5090, bought second hand, and like many others, got it home and bang, red tint. It was specifically bad in the bottom right corner. I didn't bother looking at the vol numbers and panel hours but I'm pretty sure it was around the 7000 mark.
I reset both hours and pulse, and it completely got rid of the red tint. As seen by other members, black lag/rain was present, so was black crush, but I didn't obverse any other artifacting. After much use, it settled down and everything was ok.
Now, the panel has reach around the 700 hours mark, and the red tint has returned, spread across the whole screen, but its only visible when the image is completely black, so it isn't that distracting, but I am a perfectionist!
I checked the vol numbers and they exactly match these (I cannot post links yet, so I have copied them from tubby467's post, so you will know what thread I am referring to):
My factory voltage settings:
VOL SUS: 128
VOL OFFSET: 113
VOL RST P: 003
VOL XPOFS1: 085
VOL XPOFS2: 063
VOL YKNOFS1 D: 138
VOL YKNOFS3 D: 128
VOL YKNOFS4 D: 149
VOL YKNOFSA D: 128
Apart from RSTP which was 026.
I have reduced this to 002, and will watch some content to see whether the red tint has gone, and if any artifacts are present.
I will post my findings!
