4,000+ hours on the Bright setting? It's time. I bet you, too, will be surprised at how slowly but surely you grew accustomed to what was a darkening picture over the months when you put in a new lamp and see how bright it is with the same settings.
Thanks again for your reply, Paul.R.S. I replaced my lamp last night, and now have zero flickering and a picture that's more vivid than I've ever seen it! (I bought a display model with just under 2k hours on it). I suppose 4.5k hours on the bright setting is enough to degrade picture quality
Does anyone have experience with cleaning the giant mirror on the back inside of the cabinet? I've got some linear streaks that are visible from the removable side panel which I was able to wipe away (or at least smudge) with a lint-free lens cloth. The subtle dark lines that are projected onto the upper right corner of my screen have finally gotten the best of me, but I don't want to use any chemicals until I do my research. Other posters have suggested that this reflective surface is like the underside of a typical mirror and therefore could be quite damageable.
No idea where those lines came from, BTW. My guess is that it was some sort of grease or sealant that got dripped at the factory or in transit, though there's no evidence of contamination on the outside of the cabinet...
