Ok before attempting my PX950 I just completed the adjustments on my PG25 from 2008, on a scale of 10, black scenes and the bars when watching letter box were about 6 in terms of contrast ratio, after the adjustments I’d give it a solid 8 in terms of what’s currently available.
The set_up was adjusted clockwise almost to max, by holding a mirror in front I backed off until green pixels in the darkest areas were eliminated, the VY was adjusted counter clockwise just a tad, again using the mirror to see the rise of any unwanted noise.
Last I adjusted the VA on the power supply board clockwise (seemed to work better than counter clockwise), also turning the VA fully clockwise or counter clockwise shut down the set, so I just turned it back a notch, then readjusted the Set_up a bit further clockwise, so far so good.
It’s a nice improvement over the stock settings but still a touch higher in MLL than the PX950 which I’ve yet to adjust.
Also I should point out that both my PX950 and PG25 both exhibit really nice blacks in brighter movies and not all movies with dark scenes are problematic, but The Thief and Harry Potter were used in adjusting the MLL as they appeared less satisfying.
As the current sets are already much better than the PG25 I'm really looking forward to adjusting the PX, but like Jimdish I need help getting it off the wall.
