Author Topic: Christie 4k problems John Pensky Film Handler Posts: 5 From: Moraga, ca, USA Registered: Jan 2008 posted 05-07-2008 03:49 PM                     Hey guys, I have an older house that has a 3k lamphouse that had a 4k conversion MANY years ago. The bulb and reflector are less than a year old and the picture is FAR from perfect. Ater a film has been running for about an hour, I will check on the show only to see it looks as if it flickering, the AMP meter is runing at only 1000 when it usally runs at 1500. and when i stare the show it runs the previews and i would guess the first half the movie at 1500. Im wondering if im looking at a power supply problem. The Power Supply is a CC40, says it is for 4000 bulbs so thats a good sign. Any help and ideas would be great!

It certainly looks like a power supply issue.  |  IP: Logged John Pensky Film Handler Posts: 5 From: Moraga, ca, USA Registered: Jan 2008 posted 05-07-2008 07:02 PM                     like one of the breakers on the front of the projector?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-07-2008 07:08 PM                     1. Reset the main breaker. 2. Check for all three phases present at console terminal board. 3. Check all internal high current wiring very carefully, especially the large lugs on ALL OF the DC cables. 4. If all above is good then probably a bad diode.. or very remotely the ignitor. Good luck... they are very easy to fix!

Check the voltage input and also search for loose cable. If everything is okay, check your heatsink and TB1. Thats what i normally would do.  |  IP: Logged
