Standby light blinking -unit won't stay on

I recently had cable guy in to change cable box. As soon as he left I noticed the standby light blinking on the receiver. When I turn on the unit it does go on but within 5 seconds it just shuts off. I cannot get it to stay on. Did cable guy do something or forget to plug something in? I cannot see any loose wires? Any thoughts? Thanks for your help.

Re: Standby light blinking -unit won't stay on

When it is on, does any audio come out of the speakers? If so, you may have a problem in the protection circuits. If no audio is heard, I would first check the speaker wires to make sure there are no strands shorting across the terminals, and that you have the it selected to output audio to the speakers -- Now also be sure to check the various inputs, for instance if it has a FM receiver, select that and see if any audio comes out then as well. I don't know what the cable guy could do other than knock loose a wire or change connections on you.

Harman Kardon AVR 350, Unit powers off into standby mode after a few seconds. Removed all connections and wires, problem persists. Weirdly enough, if I keep pressing the source button, the unit stays on....

It needs to be serviced. Bad caps, resistors, & possibly a transistor or two. Not an unbearable repair, but you can count on it being 100-175 depending on the shop. You followed all the troubleshooting you could without opening the unit.

My Pioneer Receiver VSX-519V has a blinking HDMI light and won't show video.

You guys mentioned the reset via the front panel, and I tried that with this very same issue on my VSX-822-k and it worked!
thought I would post the instructions for anyone else that lands here:
Reset the main unit if the receiver is generally not operating correctly. Switch the receiver into standby mode. Hold down the "BAND" button while pressing the "STANDYBY/ON" button for about two seconds. When "Reset?" appears in the display window, press the "AUTO SURROUND/ STREAM DIRECT" button. "OK?" appears in the display window. Press "STEREO/A.L.C." to confirm. "OK" appears in the window. The system has been reset.

Standby light won't turn off on receiver r 840. Tried doing what manual says and turn off autostandby mode but still light stays on. do you turn off ? i have tried everything..or does it always stay...

"Standby" means the unit has wall power but is not yet turned ON by you. When you turn the unit ON, the Standby light should extinguish and other signs of life should be evident.

It is basically an indicator that there is potential life in the unit. If it ever truly turns OFF, that is a problem.

In some cases, the STANDBY indicator may blink slowly, twice per second. In this case, turn off the unit, unplug the power cord, and check the following points.

Make sure the speaker cables are not reversed and connected to the wrong sides (+ and -) on the unit.

Make sure the speaker cables connected to the unit are not shorted. (Check both the unit end and the speaker end.)

Make sure the volume does not exceed the level that the unit is capable of producing.

When using the unit in a rack or other enclosed space, heat may build up inside the unit and cause a fire. When installing the unit, be sure to leave suffi cient space between the top, back and both sides of the unit and walls or other AV components to prevent the internal temperature from rising.

After checking these points, plug in the power cord and use the remote controller to turn on the unit. Turn down the volume before resuming playback. Confirm that there are no problems with the speaker connections and playback performance.

If this symptom recurs, request service at your nearest service center.

In rare instances, the unit may enter standby mode and the STANDBY indicator may blink rapidly, 8 times per second. In this case, unplug the power cord and request service at your nearest service center.

Try unplugging everything, including your speaker wires. It's possible that you have a damaged or crossed cable or wire causing a short that activated the receiver's internal circuit. It might have also reheated.

Let the unit sit for an hour. Plug it in (just the power), set the volume to minimum, and turn it on. If it stays on, the issue MIGHT be with a wire or connection, so you should examine all of the tires for damage or crossed connections.

Turn the receiver off, unplug it, reconnect the wires and cables. Plug it back in, make sure the volume is set to the minimum level and turn the receiver on.
