The device emits an unusual humming noise when it begins.
Hello, my projector is an Epson C0-W01. It's been functioning well for a few months until today when it started making two strange buzzing noises after turning it on. I've tried switching it on multiple times to check if the sound was consistent, but it remained the same. The fans also ran unusually long before stabilizing, and once the buzzing began, they kept increasing for an unexpected duration. Despite these issues, the projector is still working properly. Someone might recognize what's happening—please let me know if you have any suggestions or need further help. I've attached a short clip of the start-up for reference.
It's running intermittently with sporadic launches. Recently it started smoothly and the fans increased more gradually than expected, though not as dramatically as during the strange beginning. Also, the time from clicking 'Start' to seeing it appear on the screen is much quicker in the regular start, and the buzzing is absent in the standard mode.
Projectors might seem odd, but as long as they function properly, it's acceptable. I can't view the video because it uses HEVC encoding and I'm using a PC, though the audio plays fine and doesn't sound too strange. Since I'm not very familiar with projectors, I'll hold off on responding further until someone clarifies.
