My X30 has been in for repairs twice and has ruined several lamps. Going on about ten now, I would guess. After a certain amount of time, the lamps just start blinking/pulsating. Sometimes it goes away with a while on high lamp mode, sometimes it doesn't. Eventually, the blinking doesn't go away and I'm forced to switch lamps. I was smart and bought an extra lamp a few weeks after my projector was set up, so I always had a lamp while waiting for a replacement.
The lamps have all lasted between 400 and 1100 hours. Probably 600 on average. I got them all on the "three years or 2000 hours" guarantee, but JVC doesn't want to do that any longer. I guess I can't blame them.
The second time my X30 was in for repairs I borrowed a Sony HW50. After perhaps 400 hours, it did the exact same thing as the JVC
Today, I was supposed to have an X500 set up. Had to borrow money from my folks to afford the upgrade (the store agreed to give me all my money back for the X30). As soon as we get it up and running, it starts pulsating. Not as much as on a ruined lamp, but enough to conclude that the X500 isn't a solution.
Now I'm out options. NOTHING works. DLP projectors that are acceptable are even more expensive than the X500 and make a lot of noise. Plus there's no reason to think my conditions or whatever it is wouldn't ruin those lamps either.
I've recently had my electricity earthed/grounded. Wasn't too expensive. I'm using this
power filter that I borrowed from my AV guy.
Any ideas? I'm really at a loss here
