I'm also interested in hearing about people's long-term experience with 3rd party lamps.

I recently bought a used X30 with only <600 hours on the lamp. I decided to buy a "cheap" lamp for comparison (and spare), and essentially just bought the cheapest one I could find on eBay, from the seller QualifiedLamp, for $55. The lamp does not have a flap, contrary to the picture.

To my surprise, the cheap lamp has essentially the same brightness as the original JVC lamp (with 600 hours). The colour balance and colour gamut are also comparable to the original (measured with an X-Rite Colormunki Design spectro, HCFR software).

It's too early to tell how long the lamp will last, but so far I'm happy. I'm running the projector at the lower (Normal) power setting, so hopefully the cooling is adaquate without the flap.

Will do. Considering the low cost, I would be satisfied if I get 700 hours out of it. However, at the rate of 2 hours per day, it would take me close to a year to get to that. I will report back if I notice any premature dimming.

Sounds like an old version 1 or version 2 JVC lamp. Those did not usually last long and is why JVC had there lamp supplier rework the lamp design. JVC replaced around 40 lamps for my customers that received the version 1 and version 2 lamps that died early.

X30 HDMI Inputs Broke!

I was plugging the HDMI cable from my laptop to the X30, felt a little electrostatic spark discharge, and now both HDMI inputs show "No Input Signal". The projector still works with component input.

Has anyone else experienced this problem? Is it an expensive fix?

So I bought the JVC RS45 in 2012 and finished my theater in November 2012. I now have 599 hours on it. I initially used it at the normal power lamp setting and it was great. However, about 6 months ago I noticed that I was having more trouble with dark scenes in movies and television so I switched to the high lamp. Now, even on high lamp I am finding it more difficult with the dark scenes. In brighter scenes, it looks great. So is this normal wear and tear for the bulb and should I just get a replacement, or is this amount of dimming too rapid and a sign of a bad bulb? Thanks in advance!

Have you tried adjusting your aperture setting?

No, I haven't actually -- what kind of setting would I put it at?

I'm out of town on vacation now so I can't tell you for sure. Just find the aperture setting and adjust it to the left, I believe, and see what happens. You will lose some contrast though.
