MX64AR servo RED LED keeps blinking

Hi

My MX64AR keeps on blinking when I powered up with 12v source.
Is this damage? Any solution and advice offer? Thanks!

regards

There could be many reasons, but I’d recommend firmware recovery first, then see if it is still blinking.
After the firmware recovery, if it doesn’t fix the issue, check the shutdown address and see what causes the shutdown(with LED blinking)
