Author Topic: Looking for schematic / service manual Barco LPS R7633708K Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 06-11-2010 12:39 PM                     I have a Barco LPS power supply module for a Barco DP100. The module part # is R7633708K. I am trying to track down a service manual and or schematic. I can not seem to find any such material on the Barco website.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-11-2010 02:40 PM                     If this is the older SMPS Module it may not be repairable. I also looked into this for a local SLC chain that has lots of BARCOs. It turned out some of the semiconductors were obsolete. The only way back on the screen for projectors with these particular boards is to get the newer style board. Also, be careful updating the BARCO firmware on older projectors with the old SMPS boards. You can kill the SMPS and hence the entire projector by attempting to load in the later SMPS firmware. The board can be restored but only by placing it in another still operating DP-100 and re-installing JUST the older SMPS Firmware version.  |  IP: Logged
