He changes SIG CG to 01D, BRT RO to 000 (maybe he just left that there), GAIN RO to 0BC and GAIN GO to 0BC. There is a chance he may have changed one final setting that I might have missed...
...My main question was, did something happen to the light engine and this is an adjustment or patch to compensate for the problem? or, did something happen to knock these particular settings off?
Excellent observations, MooMan.
I have had a similar experience, but my tech hasn't even tried the SM yet. (we're negotiating a new appt.).
My temporary solution to a "pink push" problem was to tweak the Red Drive values *down* for all the video modes. I did this by eye using the gray bars as a reference. When the gray was neutral, I powered off and on again. Decent color, but not world-class.
I am waiting for the official fix--hopefully, Hitachi will send me a new Light Engine, cuz I don't want to deal with randomly adjusting RGB values occurring in the future!
I'm also philosophical on these repair issues. The units are so new the service industry doesn't have any real experience yet. So as long as they are smart enough to get the real Hitachi fix, they should be able to better serve us. Anyway, pioneers have to deal with lots of sh!t; no paved roads where we go, eh?
