In the middle of a movie the other night (no more than 1.5 hrs of viewing), my ceiling-mounted LT 150 developed a continuous high-pitch noise. I did the only thing I knew to do, which was to turn it off. While off, with the fan(s) continuing, the noise persisted, and was finally silent when the fan(s) stopped. I assumed it was fan-related. Out of paranoia, I also hand-fanned the pj while it was cooling itself.
The noise did not return upon turning the pj back on that night, and I had no problem with the pj last night, although viewing last night was less than 30 minutes. Up to now, I've had no problem with it; I have used about 400+ hrs of the original bulb.
Anyone else experienced this problem? Any thought as to what the cause & remedy could be? As of now, I don't intend to send it back to NEC (still under warranty) unless it recurs; is this a good idea or am I waiting for a real disaster to happen?
Thanks.
