Author Topic: Sound Problem, NO sound in Theatre? Josh Mitoska Film Handler Posts: 59 From: Brooklyn, MI, USA Registered: Dec 2001 posted 02-23-2006 06:47 PM                     Ok, so at the end of my last set the sound goes out in a theatre. I had been having problems with the reverse scan reader coming loose. That was not the issue, the booth monitor is getting sound, and when I switch to the processor switch on the monitor I still get sound in the booth, but no sound in the theatre? I have a dolby CP100 for a processor, I tried the test tone and also get that in the booth but not the theatre, I checked all the breakers, and all the amps are on? Any Ideas-thank-Josh  |  IP: Logged Thomas Dieter Expert Film Handler Posts: 234 From: Yakima, WA Registered: Jun 2004 posted 02-23-2006 07:21 PM                     First off, does your booth monitor have the ability to monitor both the sound going into the processor and the sound coming out of the amps. If so, see if you are getting sound out of the amps. If not, check the wireing in back. If the wires are fine, there should be a volume nob on the back of the amp. Note the position it's in, and just turn the nob back and forth. Sometimes the brushes get worn out in one area and just need to moved. I had this problem in Marietta once, and that's all that I needed to do fix the problem, and yes I did put the volume dial back where it was when it started.  |  IP: Logged Josh Mitoska Film Handler Posts: 59 From: Brooklyn, MI, USA Registered: Dec 2001 posted 02-23-2006 08:09 PM                     I think I have it figured out, loose wire on back of speakers  |  IP: Logged Michael Cunningham Expert Film Handler Posts: 186 From: Anchorage, AK Registered: Nov 1999 posted 02-24-2006 10:25 PM                     All of them at once?!?!? Not saying it didn't happen, but that's an amazing coincidence. Or do you run with a mono set-up?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-27-2006 10:53 AM                     quote: Josh Mitoska Ok, so at the end of my last set the sound goes out in a theatre.

Any Ideas-thank-Josh You might have a failure of the blue(I think) tantalum capacitor on the fader card in your 100. These caps just about all failed and it kills the fader voltage line and you are left with no sound in the room. I've repaced at least a dozen of these tantalum caps over the years. I am certainly alarmed at this line even if it was not the issue..... "I had been having problems with the reverse scan reader coming loose. That was not the issue" Hard to believe the NCS tech didn't take care of that for you when he was there... like I said... there are service people and then there is service..... Hope you get the 100 back on line. Its a battleship processor! We have lots of spare modules for them if you need any.

Look "after" the amps. (speakers/wiring.) Loose red reader? This is a service related issue. What brand? What is loose? LED? pickup assembly? Louis  |  IP: Logged
