anyone experience this? it makes watching movies in low volume levels impossible, the projector drowns out the audio. I have it place about 5 feet above and 1 foot back on a shelf from the seating position.

When I start the projector is starts off quiet and the faw speeds up 3 seconds after start up loudly.

my room is very cool, the air filters are cleaned constantly, and this is on low lamp mode.

is this normal?

Definitely not normal. Have you called Sanyo? Can I assume it has always done this? Is it brand new?

You might need to do a firmware update as well. Might be an issue with fan cycling - which was a problem a year ago or so until they addressed it with a firmware update. Supposedly, you can adjust it in the service menu as an alternative to modifying the firmware.

Unfortunately, I have no details on the above, as I ditched the Z1 in favor of a Benq 8700+. You might want to search AVSForum about this issue, assuming it isn't a hardware fault with the fans.

seems like its also a problem with the z1 projector central reviewed.

Having said that, we should add that a reader has written in to say that when in low power mode his PLV-Z1 goes into a high fan cool down only once every two hours. And a dealer has just tested it at our request and reported that he finds no evidence of this on his demo unit at all. So it is possible that should you acquire a PLV-Z1, you will get one that does not manifest this problem. Sanyo is researching the issue, and we will update this review with any comments provided by Sanyo as soon as we get them.
