Hi Mitch,
It could be a couple of things. There might be something that has come loose in the lamp itself. Sometimes glue softens from the heat on lamps that are not well made. Other times it’s a loose part in the lamp. Also check your filters to see of they need cleaning. If it was the ballast you would have noticed the image flickering or the color disappearing. We have heard of some generic lamps givng off a strange buzzing sound as they age. Hope this helps.
Regards,
Shelagh

Hi, I have a HD25 and have replaced the lamp a few months ago, now it’s started an arcing/buzzing noise. Is this the ballast? If so are these available to purchase for replacement?

Hi Sofia,
If the screws have come out all the way, then try using a flat head screw driver to try and gently pop the cover off. It sounds like the screw threads may have gotten stripped. This video gives you some suggestions on how to get the screws out if they have been stripped: https://www.youtube.com/watch?v=_mTFQbaT3Zc
Hope this helps.

We have Model HD25e and the bulb cover won’t come off. Any suggestions?

Thank you
