Hi
H/P means Headphone .. if you plugged a Headphone or if the plug switch internally switched to H/P you have to check it out .
you might have broken the plug inside or some parts are left in there.
Regards

HeadPhones! it's the jack, plugging in and unplugging a 1/4" solved my identical problem

It will not fix any problems with it, It just sets it back to the way it was before you set it up.

With the unit on, try a reset. If there is a small hole in the back somewhere, gently poke a toothpick in about 1/4". You should feel a soft click. If there is no reset hole, disconnect the power cord for a day or 2. If that doesn't help, you'll have to take it in for repair.

The surround sound outputs outputs ic's in the remainder of the system have opened, or there is a short in the speaker wiring, check to make sure that is not the case, if okay! you will need a repairman to assess the situation.

Hello!

I hate to ask but, was there any light interference between the remote and the Denom device?

using your cellphone camera again to test the infra red emission of your device. Aim the camera to the infra red of your device. you must see at the screen of the camera that the infra red is illuminating.

if not the infra red sensor of the device is busted or faulty
and needs replacement. It could also mean you have a cold solder on the ir sensor board inside the Denom AVR-1708.

If you have a soldering iron and lead, try to reach the ir sensor board by opening the case of your device. Resolder all terminal junctions. And see if it works normally again.

I would still suggest you have it check by a certified technician, to avoid inflicting more damage to your unit.

Good Luck!

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

set the front speaker to small or if still set in large,set the subwoofer setting to lfe+main.

Are you trying to kill it? A device has only so many emergency shut-offs it can withstand.

How are the spaces around the top, underside and back for ventilation?

0 dB isn't normally 'normal' volume.

I wonder if the fan is a self-defeating work-around because the noise might make you want to crank it up so higher so you can hear it.

Apple TV? Is it a dynamically-compressed audio signal? That would raise the average volume.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Crack the manual and run through the speaker setup routine. Maybe the center channel has drifted.

Your result indicates the unit is not passing its power up self test. The first thing to try would be to remove all connections to the unit and try to power up. If it still mis-behaves, the unit has an internal problem best left to pros unless you're pretty good digging through circuitry. If it comes up stable, then reconnect things one at a time until the issue occurs again. Detach the offending connection and look for issues in the cables or the connected unit.
