Author Topic: CP65 stuck in SR? Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-14-2004 12:49 PM                        My CP65 will only play in SR. When I push any other format button nothing comes through. The LED above the selected button comes on, but no NS or A or Mono sound. No digitals currently hooked up. Works fine in SR, but that's it. The Dolby tech seems to think its the Cat242 card. LEDs on the 242 and 441 card go out in anything but SR. I'm showing signal through the 150e in all formats. Anybody had this happen to them? What was it?  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 12-14-2004 02:48 PM                     242 is a possibility, never had one fail like this though. I'd put more money on the 443, I've had a couple do funny things in the past, strangely never had any trouble with it's predecessor the 243 in the CP55.  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-14-2004 05:13 PM                        Another guy I talked to suggested the 443 as the culprit too. He was also a little surprised at the symptoms.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 12-16-2004 04:09 AM                     It's certainly not a fault I've come across before, either the 242 isn't responding correctly to control, or control is not being issued properly from the 443. Swap some cards with another CP65 and see what happens. I know where there's a complete working CP65 available over here!  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-16-2004 08:34 AM                        A friend is coming this morning with some cards to swap out. I should know in a few hours. By the way, any idea what IC1 and IC2 do?  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-20-2004 08:37 AM                        Good call Pete, it was the 443 card. Jack Ondracek came by and swapped in a spare card he had. Bingo! (Thanks Jack)  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 12-20-2004 04:59 PM                     Next time I've got a CP65 book in my grubby mits I'll have a look and see. Are we talking IC1 & IC 2 on the Cat 443? On the whole the logic side is pretty robust.  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-20-2004 05:10 PM                        IC 1&2 are on the back side of the CP65 where you hook all the ins and outs up. Just wondered what they could be doing there all by themselves  |  IP: Logged Peter Hall Master Film Handler Posts: 314 From: London, UK Registered: Dec 2000 posted 12-21-2004 07:10 AM                        IC1 selects the type of SR installed - cat350/300 or 222SRA. I can't see how it is controlled however.. IC2 is the driver / decoder for the ID0 - ID7 format sense lines..  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-21-2004 08:58 AM                        Thanks Peter  |  IP: Logged
