Author Topic: Changeover wont manually close Frank Dubrois Jedi Master Film Handler Posts: 896 From: Cleveland, OH Registered: Mar 2005 posted 04-26-2005 01:50 PM                    Repairing it...sure...FINDING it...well that another problem. Should I look for obvious burn marks?  |  IP: Logged Frank Dubrois Jedi Master Film Handler Posts: 896 From: Cleveland, OH Registered: Mar 2005 posted 04-28-2005 03:22 PM                    The lamphouse is a Strong Highlight IIA...in case anyone is still following this topic. I still havent found the problem.  |  IP: Logged Rick Raskin Phenomenal Film Handler Posts: 1100 From: Manassas Virginia Registered: Jan 2003 posted 04-28-2005 05:18 PM                     If you have detailed schematics, and not those damned detached drawings that only show lines connecting boxes, it shouldn't be to difficult to locate the fault. First, determine what signal the c/o switch applies to the closing coil when you push it. Is it voltage or ground (earth)? For purposes of illustration, let's assume it switches a ground pulse to the coil. Take a clip lead, ground one end and then walk the ground from point to point until the coil operates. The open circuit is between the point that operated the coil and the previous one. Not knowing your specific setup I'd caution that if there are electronics along the path, you seek help from a qualified engineer. Good Luck.  |  IP: Logged Bob Koch Expert Film Handler Posts: 183 From: williams ca Registered: Nov 2001 posted 04-28-2005 08:04 PM                     Gordon; You`re again guilty of believing of what they report unto you ; is true.  |  IP: Logged Kevin Orman Film Handler Posts: 24 From: Sompting, Lancing, UK Registered: Mar 2005 posted 04-28-2005 08:23 PM                     quote: Wolff King Morrow Except most employees would get fired if they posted booth tours on the internet.

If you have any bad habits, you're broadcasting them for all to see. Including competitors, friends of the owner/managers, or tech people. Basically your post implies that whatever you're doing is the sworn policy of your company, which it may not be. Take it from me!  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 04-28-2005 08:56 PM                  I agree Dan. The pic below is an example of a theatre that has poor management and/or a lazy staff to allow the equipment to be so dusty/dirty. IF I was the owner, I sure wouldn't like for those pics to be publically displayed. It makes one wonder how many other things they let go?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-29-2005 03:45 AM                     ..true, I was wondering about this on the one pic with that box fan blowing in this processor/amp rack.

It sounds like possibly a board may have a break or crack or something...but how do I locate it?? If employees smelled something burning, and its related to this, what would most likely have burnt? A relay? PC board?  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.

But without the skills to fix it, the solution may not be. Call your service engineer. Turn off the power if the burning smell persists or you see smoke.  |  IP: Logged Frank Dubrois Jedi Master Film Handler Posts: 896 From: Cleveland, OH Registered: Mar 2005 posted 05-04-2005 01:12 PM                    Perhaps I should stress that I am confident in my skills to repair or replace anything...troubleshooting has usually come pretty easy to me...but this problem eludes me. I'll try not to take these posts as a personal assualt on my skills. And for the record, the firm who installed our equiptment has been unable to find it as well, so I'm in good company. They suggested replacing parts with other units until I find the problematic board or relay. With some items, its ok to do that, but with electrical parts that apparently burned, I'm not quite as eager to swap them around. Thanks for the suggestions anyway.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 05-04-2005 01:21 PM                        Sorry. It sounded like there was a risk of further damage, and you needed outside help. Obviously, if you find the burned component, you need to troubleshoot and fix whatever caused it to burn. If you have the skills to do that, go for it!  |  IP: Logged
