I have an AR1 that won’t power up or respond anymore. I popped the cover off and F1 is good and red LED1 is on. Power at terminals is 11.97 VDC. Are they any other checks I can do to revive this device?
Edit: I try to restore to factory defaults. I hold the Power Button for about 7 seconds and LED1 turns off and LED2 turns on. the SYS Light, Power Button and groov logo never light up.
Thanks in advance.
