We have an older DTS-6 model that will occasionally eject the disk caddy in the
lower drive during the switch from Disk A to Disk B. We always play Disk A in
the top drive and Disk B in the lower drive, though we know it will work fine
vice-versa. What happens is this: when Disk A ends, Disk B attempts to take
over. The lower drive's indicator lamp acknowledges the take over, but then the
red "CD ROM" LED on the main pannel blinks and goes out. At the same time,
the green "Digital" LED on that pannel also blinks and goes out. It is at this point
the machine ejects the disk caddy from Drive B, and, of course, the auditorium is
plunged into total silence until a projectionist restores sound. QUESTION: Is this
a sign that the disk drive is about to go, or is there another problem? This happens
about one to three times a month and started around the first of the year. Can
anyone diagnose this problem? Thanks!

It could be a drive problem, but before you get a new one, try a few things:
#1-Check the disc--take it out of the caddy and look at it--is it scratched or
messed up in any way? It must be perfect.
#2-Blow out the inside of the drive with a very small amount of compressed air.
There may be something stuck to the lens--I doubt that this is the problem,
though.
#3-Try Disc A in drive B and Disc B in Drive A and see what happens.
#4-Call DTS and get a new drive if all else fails.

I have had this happen and the drive had to be replaced I tried the steps which Jo
mentioned but to no avail, so perhaps the only way is to replace the drive our
supply dealer did this free of charge. You also shouldnt lose sound as when a fault
occurs it should go to analog sound with in about 2 seconds or so.

This may sound really odd, but it is true. One theater I know of (using the older
caddy-type units) had exactly the same problem as you are describing. Guess
what the problem turned out to be?...the caddie itself! For whatever unknown reason, every disc they loaded into a particular caddy
(they marked it) would eject the disc and drop out!
The solution was simple, toss it and get another caddy. Try this before you go
spending money on a replacement drive. If it works, a $2 caddy is a far better
solution to replacing the drive.

We had a problem with a caddy as well... the center metal disk on the top of the
caddy had come unglued and was making the disk get stuck. Problem was
discovered and fixed before the show started, so I can't say if it would have
caused the problem, but I bet it could have.
