Question about JVC HD-52G786 52" Rear Projection HDTV
I have a JVC HD56G786TV. I have had it for about 18 months. I had a DLB bulb blow after the warranty expired and replaced it. Everything worked well for a month and that one blew as well. I have now blown my third lamp since the warrenty expired. Any clues as to the cause of this?
The HD-ila sets accumulate a lot of dust in the light engine. The worst offender is the little fold mirror just under the lens. I take my set apart about every 8 months or so to clean all the dust from the light tunnel and all lenses, mirrors, diffusers etc. The picture really regains it's pop when this is done. Unless you are a skilled technician though, I would recommend against attemptimg this procedure as you need to disconnect the individual color lcds. Check with a local service center to get it properly cleaned.

I would, it's cheaper than replacing the whole TV and you can do it yourself so no labor bill. The new lamp usually comes with directions and in my experience the JVC lamps are outlasting some of the other ones.
