Why does my Promethean keep shutting down?

eisaakieisaaki Posts: 8
I have been working with these boards for years with no problems. Today I thought I was going crazy. I would turn on my board, see my screen and then in a few seconds it would shut off.  From green to red in a few seconds. Help...

  • Hello eisaaki,

    To help us look into the issue can you please confirm if it is the projectors LED lights that flash from red to green? The blinks indicate the issue, please record the LED blinks.

    Also can you please provide us with the model number of the projector. To help you find this please take a look at the below support article:

    Thank you,

    the lights are the ones on the projector that turn green for on and red when off.  
    Model number is PRM 30A

    Hi,

    Thanks for your reply.  Does the power light start flashing at all when it shuts own or is it just a solid red?

    Can you also check the filer on the back, does this appear blocked or full of dust?

    We look forward to your reply.

    Kind Regards,
    Paul

    Hi, 
    Thanks for your reply.

    If the projector is still not displaying an image, I would recommend testing another known working lamp in the projector. 
    If you need help on replacing the lamp, please see the guide below:

    Please let us know if this helps get the projector working again.

    Kind regards,

    The projector is displaying an image...   That is not the problem. The problem is that is that the projector shuts off in seconds of turning on... The image displays.

    H eisaaki,

    Thank you for your reply.
    I'd recommend factory resetting your projector to default settings to avoid any settings that may have been changed.
    Please follow the steps located on the below link:
    https://support.prometheanworld.com/article/?kb=1281

    If the projector still turns off after turning on and displaying an image, I'd recommend testing another lamp and this can be a sign that the lamp is failing. 

    Kind regards,

    Hi eireon,

    Thanks for posting on the Support Community.

    This could relate to the lamp, have you tried another known working lamp inside the projector?

    If the projector still doesn't start up correctly, do you notice a sequence to the LEDs once the projector tries to turn off?

    Kind regards,
    Adam

  • Hi eireon,

    Thanks for posting.

    This could relate to the lamp at fault, have you tried another known working lamp in the projector to see if this works?

    Kind regards,

  • I'm afraid if I buy a new lamp and it's still the same.. is 20 blinks really mean lamp fault? Please I need to be sure B4 buying a new lamp. Or would it be practical to buy the entire projector. Please advise. Thanks again
  • Hi eireon,

    This particular sequence lets us know that there is an issue starting the lamp. This could be a lamp failure or a component that starts the lamp that is failing. 
    The only way to ensure that this is the fault is to ensure that a known working lamp is tested beforehand to identify where the issue is.

    Before purchasing a new lamp, we would recommend trying one from another projector of the same model if you are able to.

    Kind regards,

  • Hi Adam thank you for your patience. This is my only projector .I don't have other lamps available. I could buy a compatible BARE lamp in china which cost e20. Is it easy to replace? I'm bit handyman. Problem is if it's other component that's faulty. This is a predicament I don't know if I just invest in new one. Thanks again adam
  • Hi eireon,

    Thank you for your reply.

    We would only recommend Promethean lamps as we can't guarantee with the quality of other lamps that may be compatible.
    We have each individual projector guides on our Support site depending on your model of projector.
    We may also have a short video showing how this is done. Please refer to the projector model on the Support site to find this information.

    Kind regards,

  • Hi I replaced the lamp with known working one but still restart automatically after 30 green flash. Also notice that the projector will start straight away as soon as I plug in. It won't wait for me to press power on. 
  • 20 green flash I mean
  • Hello eireon

    Thank you for your post!

    We would need to check the warranty on the projector. From the age the of the projector I think the warranty may have expired but we can provide you details of a chargeable repair. 

    I will send you a direct email requesting the serial number. 

    Thank you,

  • Hi,
    My promethean PRM-35 projector keeps shutting down after about 30 seconds of it being on. The lights then flash five green power and three orange lamp in a continuing sequence. It will do nothing once this happens, it will not even turn off. I then have to plug it out to turn it off. Could you please help?
