The last week or so my ST-1200HD has slowly developed this disturbing noise.

If I was driving a car and I heard this sound (and I have...), I'd think a bearing was about to pack it in and I'd better look into it before it took a lot of other machinery with it.

-just a nasty, grinding rumble.

Tonight it got so bad I didn't want to risk ruining a film in it, so I decided to take the rear cover off and have a look.

Turns out the rear cover wasn't tight!

I guess it doesn't always have to be complicated!

I have a habit of initially thinking the worst myself at times. It's hard not to... knowing the age of these projectors. I'm glad it was a simple fix Steve. [Smile]

Thanks Janice!

At first I was thinking the motor bearings were the sound. I thought "If I can't lube them I'll have to replace the motor!"

Changing a motor is a lot of work, but you have to find one first.

Then I thought "I could get a healthy ST-1200HD and this one could be for parts."

-much better I just tightened the cover screws!

What's interesting is the psychology of it. I usually run with two projectors. The other one (ST-800) already had a film threaded and the screen was down. When this happened it bothered me enough I rolled the screen back up, unthreaded the film and grabbed my screwdriver. It wouldn't have been a big deal to limp along with one machine, but I just had to find out what was wrong!
