hello, i recently buy an old pionner vsx-ax3, when i listen to the amplifier at previous owner it was ok but now when i want to power it on the red light standbuy starts to flashing and the power goes down.
what should i do? how can i reboot it?
Unplug the unit and press the on button about 10 times to completely power the unit down.
Now plug the unit back on. Wait until the red light flashes or stays on.
Now do the reset procedure to factory default.
This is the procedure for that receiver.
While holding down the TONE button
press the STANDBY/ON button for
about three seconds.
2 When you see RESET? appear in the
display, press the TONE – button. OK?
appears in the display, press TONE +.
When OK appears in the display all the settings, including
the speaker, surround sound settings and tuner settings,
will be reset in the unit to the default settings.
If that does not work you are out of luck.
That is a very old receiver that does not even have HDMI inputs. It also comes from an era when speaker impedance ranges were higher. That receiver is specified for speakers of 16 to 8 ohm impedance.
My hunch is that the impedance of your speakers are too low for that unit and it has blown it up.
