Why won't my Pioneer XR-VS500D Stereo Receiver power on?
- RrhawkinsAug 2, 2025
If your Pioneer Stereo Receiver's power supply isn't working even when plugged in and the standby LED is lit, it could be due to several reasons. First, the microcomputer may not be resetting; check if terminal RESET (11Pin) is 'H', and if not, confirm the operation of the RESET circuit. Second, the AC pulse might not be input; verify if the AC pulse is reaching the AC input terminal (26Pin), and if not, check the AC pulse generation circuit. Finally, the oscillation circuit of the microcomputer may not be oscillating; in this case, consider exchanging the microcomputer or the oscillation circuit.
