Author Topic: Barco DP2K-10s Dead Pixel? Yang Miller Film Handler Posts: 9 From: Athens, Ohio, USA Registered: Jul 2015 posted 01-09-2016 06:43 PM                     We were made aware of a "red dot" on the screen during a show of Carol today. We rebooted the server, cleaned the portal and tried again but the issue persisted. Could this be a dead pixel? The dot remains during in house created slides.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 01-09-2016 08:06 PM                     Run the test pattern "alternating checkerboard" overnight - no need to have the lamp on, just projector powered & awake with that pattern selected. If the stuck pixel remains stuck on after that, light engine replacement will be required to fix it.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

If so (particularly if it is nearing 2-years), you would have a warranty claim.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-10-2016 05:18 AM                     Thanks Dave for the hint!  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 01-10-2016 08:43 AM                     Sounds very like a stuck pixel. I've changed four light engines on two S series machines. Be aware that that technician needs to change a filter in the light pipe which is particular to the individual light engine and also install the LUT-SCC file which again is unique to every light engine. It doesn't come out like any other Barco cinema projector. The light pipe stays put, the prism & DMDs come out, more akin to a Christie design.  |  IP: Logged Yang Miller Film Handler Posts: 9 From: Athens, Ohio, USA Registered: Jul 2015 posted 01-10-2016 01:05 PM                     Thanks for the helpful info all! Is the "alternating checkerboard" test image available for download online? I'll check into our warranty status and may need to schedule a technician to do this job as I am still getting my feet and would love to learn by watching first.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-10-2016 01:11 PM                     it should be already available on your Barco machine. Replacing a light engine is not something I would recommend anybody but a qualified engineer to do. Always nice meeting someone curious who wants to learn new things though! Check your warranty and make a claim straight away if you are close to the end of it!  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 01-10-2016 05:11 PM                     "Alternating Checkerboard" is in "test patterns" but you have to select it from the list - it isn't one of the thumbnails.  |  IP: Logged Yang Miller Film Handler Posts: 9 From: Athens, Ohio, USA Registered: Jul 2015 posted 01-12-2016 04:19 PM                     It looks like we are out of warranty though looking into extended warranty options. I am also scheduling a tech to perform Maintenance Type C. I'll watch like a hawk and learn what to do next year. Thanks for the help all!  |  IP: Logged
