Acer projector H6815BD – image shuts off, red lamp light, automatic shutdown

Hi 🤔,
I'm having an issue with my Acer projector. While watching something, the image suddenly goes black, the red lamp indicator lights up, and shortly after, the projector shuts down by itself. When I turn it back on, the same thing happens again.

I've been using the projector for over a year. It's ceiling-mounted and connected to a DENON AVR-S970H receiver. The lamp has 255 hours of use. I'm using a certified 8K UHD HDMI cable. The projector software version is System 2.08 / MCU 013.

Has anyone experienced a similar issue? What could be the cause and how can I fix it?

Thanks in advance for any help!🙏

    Consult Acer Tech Support in your country as they would be more qualified on the technical part of your projector than we at Acer community, we don't have any information on your Acer H6815BD that we can pass onto you, as its service guide does not come up on our dashboard lookup. Hope this helps you out and good luck.

    Thank you very much for your reply and for taking the time to look into my issue.

    Of course, I initially contacted Acer Tech Support here in Spain and am currently waiting for their response. At the same time, I started checking the display signal parameters myself.

    Previously, I had the signal set to 3840x2160 at 67.49kHz / 29Hz. I changed it to 3840x2160 at 134.99kHz / 59Hz (i.e., increased the refresh rate), and with these higher settings, the projector seems to work stably. This might actually be the solution to the issue. 😊

    Naturally, I’m still awaiting feedback from the local service, but I wanted to share this finding in case it helps others. I couldn’t find anything about such symptoms in any official manual.

    If anything changes or I learn more, I’ll be sure to update the thread.
    Thanks again and best regards!
