My first Mit RPTV, from around 6 years ago, was an NTSC-only VS-6017. I just worked on one of the same series the other night and discovered something I wish I'd known when I owned mine, before I traded it for this IBM 600e laptop I am typing this on.
There's a register in User Menu, which has 3 selections: Skin-tone, Average and Accurate.
The first 2 celebrate all Mit stands for, as far as red goes: it read out with a 25% red push on the AVIA color decoder pattern.
Accurate does NOT. It reads out fully linear!
Back when I owned the set, I didn't know this, and quite frankly, skin-tone was what I selected to enjoy my viewing with. It looked richer.
But now that I know that red push is the same thing as blue-green diminish, I tried something out on this other set the other night: stick with Accurate setting, and goose your color intensity level up to where fleshtones are again accurate - since they will wilt when you use Accurate, if you've used the blue filter test to set color level on either of the other 2 settings - and the green and blue now will leap out at your like they should!
In fact, redoing the blue filter test when in Accurate should give you the proper color intensity level, even tho it will be markedly higher than midpoint. My end setting came out at around 3/4 up.
There may also be registers in there to redo user centering of the color and tint, but I was on a shoestring on this one, and decided not to pursue it to that endpoint. But I do recall that even tho my settings were mostly screwdriver pots, including all geo and convg parameters, there was a limited service menu in there on mine, which did cover recentering color and tint user presets. I believe it was Menu 2357, plus 5 or 4 or 6, etc. Audio and Video buttons might have already started playing a role, also - don't remember that far back these days, after having done so many Mits with the new service menus.
This is exciting, and proves that SOMEBODY at Mit had a handle on the red push controversy a looong time ago, and were willing to designate and dedicate a User setting that would defeat the red push.
Whoever they were, I wish they were still around, at Mit...
