Im having problems with one Barco 23B, this projector was removed from an auditoriom in order to install a SONY . now i am trying to reinstall this Barco projector but when i turn it on it suddenly turn the lamp off showing a red alert indicating temperature and posible problems with the liquit pump. I checked the liquid coolant flow using the refill mode and i found that nothing hapened. i disconnect the tubes that goes from the pump to the light engine and close the flow with an extra tube i have, turn on the refill mode and the liquid start to move. i dont know if a tube from the light engine is blocked inside and most important if there is a way to remove those tubes to find out. did somebody had that problem too? thanks for your help mike moreno mexico  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 05-27-2016 03:28 PM                     Looks like a system flush is needed to cure this issue.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Backflushing did not help, although one did have something moving inside - using the coolant change kit syringe I could move a tiny bit of coolant when changing direction. The syringe can make quite a bit of pressure, the flow was completely cut off. Since these were warranty projectors I did not take the light engine plumbing apart. All had been serviced according to schedule with annual coolant changes.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-28-2016 02:17 PM                     if your cooling line is blocked and it's still under warranty don't do anything and ask for a new one. Otherwise you can either ask for a refurbished one or try and fix it by cleaning the line somehow. I guess you'll have to remove the heatsinks and inspect them but not sure whether it's an easy thing to do and/or reinstalling them is going to be a delicate job.  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 05-30-2016 03:30 PM                        I replace the pump but it didnt help. Barco said that if the problem is in the light engine plumbing is not posible to fix on field so i have to send the light engine to fix. i think if i remove the plumbing but i dont wanna cause damage. thanks guys  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 06-09-2016 03:32 PM                        Good afternoon. Just to comment. i fix the problem as Dave said. Thanks for the advice, i use the air commpresor very very carfully. I put air pressure to the hoses and these were cleaned .  |  IP: Logged Ioannis Syrogiannis Expert Film Handler Posts: 147 From: Reykjavík, Iceland Registered: Jun 2005 posted 07-08-2016 09:51 AM                     If the cooling liquid is old (or maybe unused for a long period?), it may accumulate crystals on the DMDs, blocking the flow. You did the right thing. (Being cautious.)  |  IP: Logged
