There's a short in your amp section that needs to be repaired.

"enter and advanced surround keys"? I don't see that documented as a special function in the manual.

BTW: other than the Flashing light, is there a malfunction?

Page 72 describes how it REALLY resets...

Resetting the main unit

Use this procedure to reset all the receiver's settings to the factory default. Use the front

panel controls to do this.

1 Switch the receiver into standby.

2 While holding down the TONE button, press and hold the STANDBY/ON button for about three seconds.

3 When you see RESET? appear in the display, press ENTER .

OK? shows in the display.

4 Press SYSTEM SETUP to confirm.

OK appears in the display to indicate that the receiver has been reset to the factory default
settings.

If it was unplugged for a significant amount of time it possibly lost all your settings. Treat it like a brand new unit, crack the manual and set it up.

the light is an ledt they very rarely go bad ..to confirm its bad you must first see that the led is getting power --a voltmeter one end to the frame of the unit and the other to either lead on the led will confirm if its bad or not a typical led will run on or near 3 volts dc... if theres no power at the led than the problem is elsewhere

With the power off try holding Tune + and Auto surround/stream direct buttons for a few seconds to reset the protection circuits. Also, check the back panel for any loose wires. If a speaker wire is touching the metal it can overload the unit.
Make sure to keep 8" of empty space above the unit for air, as overheating can cause this problem. If it fails again, there could be bigger problems, so get it checked

I have vsx-d812 that has an AMP ERR in error menu. the troubleshooting was found to be Q696 and Q697 in the DC prot. area on "C" board, up near front toward diplay in center of c board. You can get access to error codes on VSX pioneer unit by pressing "enter" and "adv. surr." simultaneously for 2 sec. The display should show what error code you are experiencing. I believe there are three diff. error codes. 1) AMP ERR 2) OVERLOAD 3) BOAD ERR (not mistyped) I hope this helps pinpoint error code for ya.
