Greeting, Axiomites. I have come out of forum retirement because I require some subwoofer troubleshooting assistance. My EP500 v2 stopped working some time in the last month. The power LED either comes on orange (both green and red) or occasionally just red. I've tried unplugging it for a while and replugging, but it never flips to green and the driver remains dormant regardless of input signal.
When the sub was healthy, when powering on the sub, the LED would be red, but then the unit would make an audible click as the light switched to green.
I've checked the fuse and it's good. Am I missing any other basic troubleshooting steps? |
