OK, I thought I read about this before but I can't seem to find the post, so I apologize in advance if this is a rehash.
I have a Samsung HLS-5687W DLP ... I notice when it's off, I can still hear a high pitched noise coming from the set. It's not a fan, more like a power/vibration type of noise (kind of like what you'd hear from a halogen light on low). When the set is on, the noise seems to go away or diminish, though, that may be just my perception because of the other ambient noise when the TV is on (fans, etc.).
I wouldn't call it excessive, but it's still annoying.
On another note, when I turn the TV off, of course the fan runs for about 30 seconds or so ... when it stops, it's fairly audible as it slows. I wouldn't call it a grinding, more like a gentle "thump...thump...thump" as it slows. It's otherwise quiet so I'm not bothered unless it's a symptom of a problem.
Any advice? Thx!
