In your experience, is this just a case of the bulb wearing out? JVC claims 4500 hours and 1800 seems awfully short of that. How often do you replace JVC bulbs?
How often (if ever) do you clean the lens?
You'll never get 4500 hours. I remember my x500r (same basic series as your RS6710), bulbs would get put on high at 1000 hours and replaced around 1500 hours. New bulb brightens it back to where it was. You should just get a new bulb and see.
The newer series starting with RS500 seemed to about double the usable life of the bulb. I hit 3200 hours on my last RS500 bulb before even having to go to high.
