Not only is the workflow different, but in the end, you have to make picture quality sacrifices to end up with an artifact / misfire free picture after reset.
Here is the workflow for the 60 inch sets.
First set all voltages to default:
Vsus adjustment value 128
Vysnofs adjustment value 68
Vyprst adjustment value Varies (but you can set it to 18)
Vxpofs1 adjustment value 105
Vxpofs2 adjustment value 63
Vyknofs1,2 adjustment value 86
Vyknofs3 adjustment value 96
Vyknofs4 adjustment value 143
Vyknofs1,2/3/4 adjustment value 128
1. Display Combi Mask 10.
2. Raise SAD in 10 tick increments until Combi Mask 10 is clear of misfires (you will have to get very close to the screen to make sure there are no stray misfires in the white lines of the pattern). On my set, I ended up with SAD at 218.
3. Put up a black clipping pattern (black clipping pattern from AVSHD709) or anything with near black content and check for white / green misfires on near black.
4. If misfires near black are present, lower S1 from 86 to 1 to remove sparkles near black. Black clipping pattern from AVSHD709 can be used to see the effect of this adjustment. I don't have a big enough sample size but it seems like sparkles near black don't occur on the 2009 builds.
4. Put up a black field. If red tint is still present, lower RSTP in 1 tick decrements.
5. If red tint persists after lowering RSTP to the minimum value (1), you can lower VOL SUS by 10 to 20 ticks.
6. Use a black clipping pattern to set your brightness (typically +1 or +2).
7. Perform a calibration, as the internal grayscale was thrown off by the pulse meter reset.
Let me know how it goes.
