Pioneer VSX-D810 Amplifier Poweringoff message when turned on

Hi, my amp displays "poweringoff" within 5 seconds of being turned on.
I'm fairly certain this is the protection mode, but I don't know how to
reset it. I know that some models have a combination of two buttons you
hold while powering it on, but I can't find any info on this model on
the web.

I don't have the SM, and I'm not sure I want to shell out 15 bucks to
get it. If that doesn't fix it, I don't have the electronics skills to
go any deeper -- at that point I'd have to take it somewhere to be
looked at, and the 15$ would be a waste. Does somebody happen to know
the combination for this model, or maybe some common ones that I could
try that might apply to the 810?

Much obliged!

I have a note at the back of my bench that says " To reactivate system
control processor, press 'ADVANCED SURROUND' and 'ENTER' ( by jog )
together for 2 seconds ".

I'm pretty sure that this was for a Pioneer that I was having similar
trouble with, but it is likely that if yours is going into protect mode,
there is something actually wrong with it.

Probably wasn't for the same model - I can't remember now - CRAFT's disease
and all that ( !! ) but worth a try, as often, the same codes do for more
than one model from a manufacturer.

This problem can be caused most commonly either from overloading the unit,
or by shorted finals. I'd be sure to check for shorted speaker wires. These
units if I recall correctly use a STK like hybrid IC output device, and I
have seen several output failures.

To reset the protection circut press and hold the Advanced Surround and
Enter puttons simultaneously for at least 2 seconds. If the unit resets,
then goes back into the shutdown mode, you are most likely dealing with a
bad output IC.
 
Well, I don't have those buttons (Adv. Surround & Enter). I have:
Class, Memory, Band, MPX, Speakers, Midnight Station - & +, Tuning - &
+, Direct, Monitor, Digital NR, DSP Mode, Signal Select, Dolby/DTS, and
Tone.

I've tried a few random buttons while powering up, no luck.

I'll have a look and see if I've got a manual for it, but don't hold your
breath ...

I appreciate you taking a look. I'm kinda tight on funding atm, and my
current stereo died on me -- if I could get this one working, that
would be amazingly good luck. It's got video and optical ins, both
features I really needed and my old stereo didn't have 'em. Because I'm
running audio from my pc, I get a lot of "power hum" using analog
lines, so the optical is virtually a necessity.

Finally got round to checking through the manuals, but haven't got one for
that model - sorry.
