Author Topic: Lamphouse Problems Mathew Molloy Master Film Handler Posts: 357 From: The Santa Cruz Mountains Registered: Nov 2000 posted 09-22-2001 02:57 PM                     I'm hoping somebody here could suggest possible solutions to these problems we're having. One of our lamphouses will occasionally trip the breaker when we hit 'start'. We replaced the breaker with a new one but that did not help. The diodes checked out good as well. Any suggestions? Now in our second lamphouse, after replacing the bulb, it is striking very hard. It will occasionally flash with a "whoomp" sound (like a flame blowing out, but fairly loud) while trying to strike. Any advice would be appreciated! Oh and they are L.P. Associates. -Matt  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Check this unit for connections also since some L.P. associates units use a quick disconnect plug for control that could be corroded. the boost circuit in some L.P. rectifiers can cause problems. L.P is in Los Angeles, in the Hollywood area, if you need parts.

The arc was trying to strike between the negative end of the bulb and the reflector frame. This was cured by using their teflon negative reflector fitting, instead of the original metal one.  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 09-23-2001 07:59 PM                    yes the kniesleys did have a problem with arcing onto the frame...at the old theater I used to work at we had four of these lamphouses....we had to make sure that the connection cable was not to close to the frame when we installed a new bulb....they also had a hard time striking when hot....the tech at the time remedied that problem by replacing the existing ignighter with one ment for a strong lamphouse....never had a problem after that....  |  IP: Logged Freddie Dobbs Expert Film Handler Posts: 115 From: Pinson, AL, USA Registered: Jun 2001 posted 09-24-2001 09:42 PM                     I dont know where the tesla is in the LP but you might want to inspect it for arcing to the frame...  |  IP: Logged Mathew Molloy Master Film Handler Posts: 357 From: The Santa Cruz Mountains Registered: Nov 2000 posted 09-25-2001 01:26 AM                     Thanks for the advice! We opened up the lamphouse to discover the lead was just touching the reflector and melting away nicely... D'oh!  |  IP: Logged
