EST-P1 Power On then Power Off

we have this client (university), we installe 24 unit of EST P1 with activeboard ABV587PRO, for the past months they are having this issue that during school hours when they are using the projector, it will just suddenly shut off, then when they start again, the led light will turn blue then the fan will blow to the maximum that you can hear it, then when it is starting and there is light in the projector, it will suddenly shut off again, it will cycle like this until they no longer use it.

they have 2 spare EST projector that they will use in replacement of the problem projector, but when we connect the problem projector in our office for observation, no issues is showing.

and this is happening to random projectors, any of 24 projector will be like this then when we pull out for observation in our office, it will be ok. then we will just put it back again for use then it will be ok.

first we try to replace the lamp, but that same projector will have same issue in like 2 or 3 months, even if we use lamp from different projector.

we are really confused on what was the real issue.

hoping someone can help us.

  • Hi Jcestimos,

    There could be a problem with the cable inside the boom that goes from the projector to the computer.  Since you have taken that projector down and there isn't an issue.  Does the projector that you put up as a replacement is that showing the same issue.  A better understanding of how these are mounted will help us diagnostic the issue.  The cable that goes from the projector, does it go to a wallbox or faceplate?  Bypass that wallbox/faceplate to see if that is the issue.  

    Thank you,
    Pam

    the replacement projector will work but for 2 or 3 months only, then we will pull out, test, we wont find any issue, then it will stay in the office until other projector will have problems, then we will put the first projector again then it will be ok.

    the cables were run in the in the back of the activboard frame. the power comes directly from the wall socket and dedicated only to the PC and projector.

    promethean local distributor here in bahrain informed us that maybe there is a power fluctuation, will that be a factor also on why there is problem with the projectors?

    Hi jcestimos,

    It could indeed be a power related issue or alternatively, the environment of the classroom could be the issue, if this is too hot, the projector may also be shutting down and the fans making an increased volume to cool down the lamp.
    When the projector is powering off, does the university notice any sequence to the LEDs? For example, does the Power LED or Temp LED show and flash through a sequence?

    Kind regards,

    the room is well ventilated as this is a medical university

    what the people there in the university is doing is just that after the class is finished they will just leave and the projector is set to 10 mins to turn off. then in the morning they will come and turn on again, this is the regular routine in that university

    Hi jcestimos,

    Thanks for letting us know. 

    As you mentioned that this happens every few months, is there anything different that happens in the room that could reflect a power issue?

    Kind regards,

    this is the typical wiring for the projectors and attached link us a video of the issue.

    [REDACTED] is the serial number for that particular projector
  • Hi Jcestimos,

    The seven LED flashing is the lamp door, make sure the lamp door is secured with the screws.   
    Here is the link to our document for the EST-P1 projector https://support.prometheanworld.com/files/public/pdfs/Promethean+EST-P1-v1.pdf.  Page 44 & 45 with help with the troubleshooting of this projector.

    i don't think that it's a lamp door issue, as you can from the videos the blinking is more than 7 or 10 even before it restart again

    hi, just an update.

    we pulled out this same projector from the university and tested it here in our workshop, from the start it worked fine, just one click from the control and it started normally.

    we let it on for about 5 hours yesterday, and today morning again it is working well.

    the power supply here in bahrain is 240V 50Hz.

    as of the moment they have 6 more projectors that have very same issue, they have 24 units of projectors, this is a medical university and this is critical issue for us as they are one of our biggest client. 

    they want to have a solution as soon as possible as it is affecting the class session, teachers and students are already complaining

    is there a firmware or a software solution that we can apply to solve?
