Hi,
I'm trying to troubleshoot an issue with my Pioneer amp (VSX-S500).
After the power in the street was turned on and off rapidly by an engineer, my amp stopped playing sound.
The HDMI plays through fine, but the amp doesn't make a sound, even when I plug in the headphones.
It is not muted.
All menus seem to be working fine.
A relay gives a loud click after I turn it on and when I turn it off.
When I turn the volume right up, the headphones hiss (the hiss gets louder the more I turn it up past 0db).
I've done a reset of the amp to factory defaults by following the sequence described in the manual.
Can anyone suggest anything I can do to narrow down where the problem is?
So far I have:
- Tried with all or some speakers connected (all the speakers were tested before and after and work fine).
- Tried with no speakers connected, using headphones that are known to work.
- Tried the above with HDMI and inbuilt tuner.
Later I'm going to try and get it to produce test tones, but I haven't got time right now (I'm at work).
Can anyone suggest further ways to troubleshoot and diagnose?
Many thanks
Dave
