How to troubleshoot GRAF & MEYER eXentro PA-8250 with no sound and no power?
- MMichael DixonAug 9, 2025
If your GRAF & MEYER Amplifier has no sound and no power, it usually indicates a power supply issue, either with the power line or the amplifier’s power supply. First, try turning the amplifier off and on again. Also, ensure the AC power cord and 48 V input are properly connected. Check for a secure fit between the plug and AC receptacle, and try other receptacles. Verify the power at the AC receptacle and check the DC battery voltage. A blown amplifier fuse could also be the cause, so replace the fuse if necessary. Lastly, the amplifier may be in protection mode, so allow it to cool down.
