Hello all just wondering if anyone knows how to do a hard reset on this model, XVR58C-21D-8CH-V1.1 ?

Hey there people
While working on my Acer Aspire with the OS failing to load, I encountered a motherboard number of DA0ZHQMB6E 0 REV: E. I was getting nowhere fast or slow, for that matter.

D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical... -
Hi,
The machine was/is password locked for BIOS. You can imagine I am writing here because things did not go as planned...

I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)
I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen.

The set appeared to be working normally, but it shut down after about 15 seconds,...
