Antsle will not start or respond

My Antsle (0.12) was working fine, on a backed up UPS. At some point in the last month, the machine stopped responding. I tried every possible access. It does not ping. There was a solid red light on the front panel and a flickering yellow light. With no other option, I tried powering down by pulling the supply cord. Now I have a red flashing light. No response, no reboot, nothing on the console. Help!

Hi Randal:

Thanks for reaching out to antsle Forums.

Can you help us hook up keyboard and monitor to your antsle?
Do you have another antsle Power Supply that can be used?
If not, you can purchase one below:
