Throughly disappointed with my new Yamaha A-3000 Integrated.......

well, I love it when it's not shutting down.  Finally called the dealer and told them I'm done with it.  From the first day, it shut off and went into protection mode after 10 minutes of listening.  It's doing it all the time now.  I did figure out how to reset the amp, but it continues to go into protection mode.  Here's what I've done to track the issue down.  Am I missing anything?  By the way, I'm a user, not someone who can track down voltages, test wires etc etc.

1. Pulled power cord for 30 minutes- I use a PS audio PC
2. Unplugged all connections- amp stayed in protection mode with nothing plugged in.
3. I then figured out how to reset the amp.  The amp then worked for for some periods before shutting off.  Yesterday for example, playing vinyl, amp shut off after 5 minutes.  I then did the reset and listened for 2 hours without shutting down. 
4. Today, after 5 minutes it shut down again.
5. Doesn't matter if it's vinyl or CD playing.
6. I just unplugged my Sub now as the rca cables are a bit bent up; however it didn't affect play for 2 hours yesterday without shutting off.

Disappointed as I was looking forward to breaking this in over Christmas break........

Were you thinking perhaps the sub was plugged into the speaker connections?
I was asking if you had ever done that to make sure it wasn’t the case, because if you had ever done so it could easily account for the symptoms you described. And I suspect that the Martin Logan sub you mentioned in another thread provides both speaker level and line level inputs.

Also, perhaps pointing out that connecting a sub to the speaker terminals of this amp is a no no will prevent someone else who may read this thread and has the same amp from damaging it.

Good luck. Regards,

Thanks Al got it.  I know I didn't do that.  Will wait on new unit and go from there

Regarding Sub connections:  

"connecting a sub to the speaker terminals of this amp is a no no"

Can you run a connection from the terminals on the speaker to the sub?

My sub only has 2 RCA connectors in which I connect to the pre-out right/left on the amp

honeybee2012, I would error on the side of caution and NOT hook an active sub to the terminals of the speaker if that speaker is connected to the AS3000.  From the Yamaha AS3000 Manual:

CAUTION

Because the power amplifier of A-S3000 is of the floating balanced type, the following types of connections are not possible.

Connecting with the left channel “–” terminal and the right channel “–” terminal as well as “+” terminals (Fig. 1).

Connecting with the left channel “–” terminal and the right channel “–” terminal inverted (cross connection, Fig. 2).

Deliberately connecting with the left/right channel “–” terminals and metal part on the rear panel of this unit, as well as accidentally touching them.

Do not connect your active subwoofer to the SPEAKERS L/R CH terminal. Connect it to the PRE OUT jacks of this unit.

Do not connect a component with no volume control, such as a CD player, to the MAIN IN jacks, as the volume level of the signals input to the MAIN IN jacks is fixed. If such equipment is connected, a sound may burst, and the unit and/or speaker may be damaged.
