One of my Eris 8 monitors is producing no audio..The monitor was turned off for several months while I waited until I could get a new computer. When I plugged it in and turned it on, the blue indicator light turns on, but when I play music, nothing comes out. I did notice that when powering off the monitors, the blue indicator light turned off immediately on the good monitor, but faded out on the one not working. I live near Hilo, Hawaii and am looking for a repair shop. Can anyone help?
