The processor wakes up in non-sync like it should, but the mute cannot be disabled by pressing the mute button. the local/external fader panel will switch to external, but wont switch back. I hate running bypass. any help would be appreciated Josh  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-18-2001 04:14 PM                     Do you have any form of automation hooked up to the unit? If memory serves, there are a couple of different automation boards on the back of the unit. Which one do you have?  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 10-18-2001 04:48 PM                        I was a bit suspitious of that board, so I removed it. It didnt help at all. But, if it helps, the board number is cat. 231 Josh  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 10-18-2001 04:49 PM                     I have had this exact problem. The mute switch itself was faulty. Replaced and off we went. Also check the ribbon cable and plug from the front panel card, and the control logic card.  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 10-18-2001 05:07 PM                        I will give that a try Pete, Thanks  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 10-18-2001 09:44 PM                        well, I am going to have a replacement cat 243 card shipped out, hopefully here tommorrow. after comparing this units function with another cp 55, we think the control card is at fault. after trying to trip the mute with the automation board and failing, the 243 is about the only option left. I'll keep you updated, Josh  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It is a sure fire way when you have multiple units to try! Steve ------------------ "Old projectionists never die, they just changeover!"  |  IP: Logged Paul G.

I am not sure if the card was shipped Blue label or Von Ryan's express. Paul  |  IP: Logged
