Play some test patterns, red, green, blue and white. Your light engine - or T-block - will probably need to be replaced.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 03-29-2016 04:48 AM                     What type of projector is it, how many hours on it's counter? - Carsten  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 03-29-2016 06:20 AM                     Oops, sorry, it's in the thread title. First, order a service technician to do a good cleaning of the unit. I have never seen blue center-blotching as a result of dirt in a 515, but you should still give it a try. The 515 has suboptimal air inlet filtering and needs regular cleaning in 'normal' environments. Also, play a grey pattern to see a discoloration pattern over only part of the screen or the full screen. Again, how old is this unit/how many operating hours? - Carsten  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 03-29-2016 05:32 PM                     also, check TEST1 pattern and compare with grey-10 full. TEST1 does not take into account the colour calibration and uniformity.  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 03-30-2016 08:23 PM                        This projector has 12043 operation hours  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 03-31-2016 06:17 AM                     That's enough to cause issues. Do you know wether it is running with all 6 lamps on, multiple shows a day? The maintenance manual has cleaning instructions. I would first open the side panel, remove the fan panel, then check with a torch the RGB filters (Sony calls them Lens 2 R/G/B) for dust and grease buildup. If this unit never had a regular maintenance cleaning, better get an experienced Sony tech to do a full cleaning. From my experience however, it does look more like a permanent damage than just dirt, but you may be lucky. The Lens 2 R/G/B panels can be extracted rather easy (single screw) and reinserted without any realignment necessary, and be cleaned with standard tools like high-grade isopropanol or ethanol and optical wipers. Try this, and see if there is improvement. I suggest to get the maintenance manual first. - Carsten  |  IP: Logged Mike Moreno Expert Film Handler Posts: 200 From: culiacan sinaloa mexico Registered: Jul 2008 posted 04-19-2016 03:18 PM                        the R/G/B panels are clean. i think it has somethig bad the support tech will come next week in order to check. but they said is a bad T-CORE.  |  IP: Logged Ariel Vocal Film Handler Posts: 20 From: Cochabamba, Cochabamba / Bolivia Registered: Apr 2012 posted 04-30-2016 06:32 PM                    Hi Mike, a friend of another cinema had the same problem, but in the image existed yellow spots, apparently is the SRXRD805 component, but SONY say they do not replace just that part if not the whole unit T-CORE, and they it is extremely expensive ... above $us 18K!! You managed to solve the problem? or at least know what the problem was? Regards!  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 05-01-2016 04:10 AM                     The T-core is all glued together that's why it cannot be repaired.  |  IP: Logged
