If you're sure that the AC plug and the voltage regulation is fine, there must be a problem with your amp. You had better get it serviced. There could be couple of blown capacitors; furthermore, you might have your power supply out of duty.

You had a post that said you had fixed faulty power relays on DSP-a1 - how do you identify the relays that need cleaning?

That your amp does not go into the second stage of powering up indicates a fault which is causing it to sit in non-active mode. This could be due to blown output audio module or transistors or a fault in the safety circuit itself. It is not a fault the non-technician can repair and it would need to be sent to an authorized workshop.
I have seen situations where users unknowingly leave frayed ends of wire shorting across the speaker output terminals which can lead to this sort of fault. You could check this out also.

My AV receiver turns off a couple of seconds after I turn it on. I did what the manual said, unplugged the power source and removed all of the speakers but it continues to do the same thing. Anything else...

you may have a bad Earth power 110 V AC cable connection which makes such hum / buzz even nothing connected..
Check the connections between components and make sure they are secure before proceeding to the next Step. Sometimes, loose connections can cause a hum.
  • Separate the audio cables from the power cables; electromagnetic interference from the power cables can cause stereo hum. Use cable ties to secure the audio cables away from the power cables.
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • 5 Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    Hi, I have a Harmon Kardon Model No. AVR 325 that keeps clipping. When I push the power button the display turns off like a second after I push power. Seems like its a easy fix. Nothing if fried visually...

    it sounds like Amp burned, but not all burn parts you can see, you have to measure them by DMM. I guess at least one AMP transistor shorted. you can check SPK terminals by DMM DC, it can be easy to find different with other one

    Speakers don't plug into inputs. Check your work.

    Try powering it up with nothing attached, then proceed to attach things (like a speaker to the speaker terminals) and see what happens.

    My pioneer receiver vxs-918v standby/on button is blinking and will not work. We were watching a movie last night and it just went off. It will not do anything except blink. The manual just says call a...

    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

    Protector flashing red when off.

    If the speaker wires are shorted, it may be in protection mode. Try turning it on with no speakers attached.

    If you've already done that and still have the same problem, it's broken and you should return it.

    Read the manual. You've either got crossed speaker wires, it's overheating, or it's a more serious problem. The same just started happening to mine, so I'm taking it in.
