I have a question for you guys regarding my RS40. I haven't had any issues other than the first bulb went at 227 hours. No lock ups, no IR issues, no HDMI handshake issues (yet). My second bulb has 492 hours on it. But lately I've noticed black levels have no gradient to them. In dark scenes it seems the black levels are getting crushed and there is no distinction to gradients. That makes dark scenes impossible to view. Bright scenes seem fine. I have calibrated it with the AVSHD disk. I've tried many movies and the dark scenes are all the same - too dark. This is a recent change as previously I could see the darker scenes no problem. Any ideas?
