Re: shutting itself down
Its usually not a fault that you will see unless somethings burnt up. This is solid state electronics and you dont see this stuff go bad. But in the meantime try disconnecting the speakers and see if it still goes into shutdown and at the same time have a dc multimeter attached to the speaker outputs. If the unit comes on and you dont see any DC at all or very very little B+ on both speaker terminal sets then you may have a defective speaker. If you do see dc then thats why the protections comming on so you dont blow out your speakers. If you dont have any equipment or dont have any electronics experience I would then take the unit to a repair person for an estimate. Good Luck
I have a kenwood VR-305, for no reason it would shut down. Some times it would work fine for a while and some times it would shut down as soon as you would turn it on. I checked websites for trouble shooting and called Kenwood, not much help. It would shut down if you were to flip the speaker jack inputs. I took it apart thinking it had something to do with the speaker jacks. What I found was a cracked solder connection, the location was at the very back and bottom of circuit board unit, which one of the back screws that holds on the speaker jack goes into the back pannel and connects part of the speaker jack to the circuit board to complete the circuit. I resolder the connection and now it works great.

Once the set shuts down, wait for the unit to stop blinking. Once it stops hold in the input and menu buttons for 5 seconds. The TV will then give you an error code. A 6-1 or a 1-8 error code would indicate a bad Color wheel. Which I think is the problem you have.
Have you provided adequate ventilation? May be your receiver is running hot and when there is loud volume it is obviously getting overloaded. There are no fans inside 674, the only way to provide good ventilation is to keep the top of receiver clear for atleast 6 to 8 inches.
Hello Sir, hi, you have power supply problems, this is caused by a bad part on the main board or on the power supply board to overload, when overload happens, the power supply immediately shuts down to prevent further damage. my first advice is call your dealer for proper service.
Blinking indicates that the power source has shut itself down because another component has died and it's shorting it. Unless you have experience in electronics it's time to take the receiver to a repair shop.
Take every single cable out of the unit, now power on the unit.
If the power protection still shows then there is an internal fault, usually a short or a component defect.
If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.
Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.
This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...
regarding the Pioneer VSX-912 blinking standby light. This is how you reset it; press the "advanced surround" and the " enter" at the same time for about 3 seconds. Make sure you press the ENTER on the reciever (its the one on top next to the small dial) If you press the "ON" instead of "ENTER" it will not work. If an error message comes on and shuts the unit down, just reset it again. This should save you some $$$$. To bad Pioneer did't put this info in the manual.
