OK, so I just got a 42" A10 set, and, despite some 'screen door' concerns, am pretty darn happy with the set. Games look excellent, SDTV looks fine to me (it's not the TVs fault the SD signal is so compressy and poor); movies and different types of HD content (netowrk dramas, sports, DiscoveryHD stuff) look good to me, despite black level issues. I am still considering swapping it for the Samsung 46" 67-series DLP, but that's for another time. . .
However, the poppy reds have been driving me nuts, so I went ahead and adjusted the CH_AXIS1 value as suggested in the first (ammended) post of the thread to 0002 on all inputs/resolutions I could muster.
I noticed I had to make the changes for each resolution on each input, eg. for the Xbox I had to do it with a 720p game as well as a 480p game (thank goodness I still have MVP05!
), for the cable box (the SA 8300 HD DVR box through the HDMI) I had to do it for each 1080i and 720p, as well as 480i (don't know as I've seen a channel sending 480p). For the internal antenna, I had to do it for all three as well.
Anyhow, I have two questions: first, in the instructions to lower the CH_AXIS1 value (very well presented, BTW, thanks deconvolver) it states you push (6) to lower that setting. What do you push to INCREASE that setting? If I were to want to go back to the original setting, or try out some others once more feedback comes in here, how could I do it? Does that setting cycle through using (6) or does it get to an end point; if so, what to push to go in the other direction? I fear pressing buttons at random to find out, since this service menu business is so cryptic and so dangerous to make a mistake with.
Secondly, and this came to me as I was about half way through adjusting the various inputs, does anyone here really know what that setting is doing? What is "CTS?" What is CH_AXIS1, and what do those values mean? There are far more values than I had expected from reading the step-by-step. Some seem to work incrementally, but in groups. Also, the difference from 0008, say, and 0002 seems to be far less than the difference between 0004 and the others down in that 000x area.
Now that I've made the adjustments (very nervous moments for this first-time service menu tweaker), I must say I am very pleased with the results. The Georgia Tennessee game is now much more easy on the eyes!
(Those reds on the GA coaches' jackets on the sideline are still pretty poppy, though I think it's a CBS thing since not all the cameras seem to be too poppy in the reds.) I do wish, however, that someone with better test patterns than I have (only a handful of THX DVDs, so the DVD input is the only one I had any kind of color bars for) or better yet, some diagnostic equpment as well, could give some definitive info on these CH_AXIS1 settings, of which there are so many. I am curious how deconvolver and/or npm came up with this fix and settled on the 0002 setting as opposed to any of the others.
I don't regret making this change, not at all, and of course am confident that I could return them to their factory settings (assuming I can figure out the answer to the first question), but I admit to having a slight twinge of concern that I have changed more than just the red-push.
BTW Thanks to all who have posted here with their settings. AVS is a tremendous resource, and the posters are the reason. So, thanks!
