If the power indication LED does not light, first, ensure the 8U-110081-2 AC UNIT is properly inserted. If that's not the issue, check if power is being supplied to the coil, IC301, and IC303. If power is being supplied to these components, there may be a malfunction of IC301 or IC303.
What to do if my Denon PMA1510AE Amplifier turned on, but sound does not output normally?
If the power is on but there's no sound output from both channels, check each connector to ensure power is being supplied. Also, verify if power is being supplied to the detection circuit. If power is present, there may be a malfunction of IC301, D313, TR318, or RL101.
