That is, What brand and what model and if there is an error with a number, use the error number.  |  IP: Logged Uugantsetseg Tsolmon Film Handler Posts: 13 From: Ulaanbaatar city, Mongolia Registered: Sep 2015 posted 10-27-2015 11:01 AM                        I'm really sorry, This is my first post. Our projector is NC2000C and our lamp is ushio DXL-40SN/L While our projector is playing, Projector turn off because "Lamp unlit" error. When we turn on projector and lamp after cooling, that's ok. So, what was happening?  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 10-27-2015 02:58 PM                     Maybe just a faulty lamp? First thing is to replace it and see what happens.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 10-27-2015 06:41 PM                     Nope - first thing is to wait for this to happen again ;-) - Carsten  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-28-2015 03:24 PM                     Lamp unlit signifies two possibilities. 1. A bad lamp. 2. A bad igniter. Always do #1 first. If the problem comes back then it's likely the igniter. If you have more than one NC-2000 at a site you can move the igniters between different projectors and see if the issue follows the igniter. Igniter is VERY easy to swap out. A bad rectifier gives completely different errors and indications.

In an NEC projector a Lamp Unlit error can happen if then system tries to light the lamp but it doesn't light for any number of reasons. For instance, a lamp that has lot it's seal will also cause it.

The original post says the projector shuts down during the show.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 10-29-2015 11:44 AM                     Why would it shut down? Does he mean just the lamp is off with that error up?  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 10-29-2015 01:35 PM                        Might be a good idea to have a visual look at the lamp. Last year, one of my Barcos would fire off the lamp. Then, after a few seconds of what seemed like OK operation, the lamp would shut down and I'd get a red tail light. Light it again and the cycle would repeat. Turned out I had a gassy bulb, though it wasn't obvious until I pulled the lamp out to have a look.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 10-29-2015 01:59 PM                     Dave, The projector senses the lamp has turned off. If this is not followed by other errors (temperature, ballast, coolant) the first step is to replace the lamp as that should mean that the lamp has flamed off on its own.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-29-2015 04:21 PM                     Yep! Still betting it's just a bad lamp...

Now our projector has worked OK. We reset "bulb alignment setting", solved the problems. So We think that "Lamp unlit" error reason is incorrect location of the lamp.
