Hi all: I should be taking delivery of my new Sammy HL-S6187W within the month (from TVA) and cannot figure out whether to have it professionally calibrated or whether it can be a DIY job. I've been working with a pro-installer to the extent that I've bought my speakers and remote through him, and otherwise picking his brain within reason, and I AM a serious DIY kind of person. He deals with plasma and projectors only (no DLP RPTV's) and says that his crew never needs to do much beyond the set-ups that they've learned over the years. He's convinced that by just running through the set's menus I should be able to tweak to the extent I would probably find necessary. Yet, I read some of these forum pieces and get the sense that to really get it right, I ought to spend a couple of Franklins or so to have a pro come in and do it. I'm comfortable enough to begin to wade into these menus myself, but having never done this before, am slightly anxious that I could just as easily make an errant turn and get myself into big trouble too! Am sure that if someone walked me through it, I'd figger it out quickly and that would be it. Your collective thoughts will be greatly appreciated!! Thanks in advance.
