I installed a new lamp, but no change. For the first half hour or so the unit operates at reduced light level with very reddish tones. After sufficient warmup the spectrum becomes white (6500 degrees setting), although it doesn't seem as bright as formerly. I've written JVC, but no reply.
Could it be a problem with the ballast for the lamp? I don't really know much about such things, but there could be a problem with the power being supplied to the lamp. Good luck with JVS customer service, they can be hard to get a hold of these days.
Our bulb did that as well. Went real dark and I thought it was the movie. However, it wasn't. An hour later or so there she blew! Thats the 3rd bulb we've gone through. Only 300 hours on projector. Were working with JVC now for a replacement.
