Denon x4800h new humming noise

[Sean de Silva]

there is no earthing at all in my house and no one has this in my entire new colony area

This is shocking to say the least. Afaic all power sockets connected to hifi gear must be properly grounded to safeguard your equipment and yourself in the unforseen event of a short circuit! Get all your community/colony folk together, complain to your local electricity distribution company and ensure that they install the ground connection at the earliest. I shouldn't be saying this but you and your equipment is living on borrowed time in the absence of AC power grounding.

he came yesterday and said noone these does earthing it destroys equipments more if compared to no earthing.

My 25-year-old house has earthing. And for new homes, earthing is a must; without earthing, the electrical department will ask you to do it. This is a new rule. Only earthing can prevent damage to your all-house old equipment from high voltage or lighting cases. This is basic. After this, only the lighting resistor or MCB

That's vibration then. You won't feel static electricity discharge when you touch plastic, though some plastics help build up a static charge through friction.

Can you try an app like https://play.google.com/store/apps/details?id=org.intoorbit.spectrum&hl=en_IN and record the vibration and then make one more recording with the app with the rubber pads in place and there is no vibration. Ensure the duration of recording use the app is the same in both cases,.

You can then use https://web-toolbox.dev/en/tools/image-compare-slider to compare the images. If the app is able to pick up the vibration then it will show up in the compare.

can you tell exact instructions how do i use this app?

Who the hell is this joker. Looks like he is missing earthing in his brain .

not an option for me. can you tell if this denoin vibration can go away or not

I feel no one has visited.no electrian will advise against the earthing.its basic necessity without which even electricity board will not give connection. I feel it's waste advising anything.
From the day one people are pointing towards electric circuit earthing problem.
Where the hell neutral line is connected in that building.

denon vibration? I dont know about this. Maybe because of some hardware issues? Its just a guess, I dont know. I am sorry.

But please try to earth your home; this is not for AV equipment. It's for your safety and also other electronic equipment in your home. Maybe that electrician doesn't know about this. (If he doesn't know he is not an electrician ) he maybe a plumber.

Oh wow!!
Someone reinvented basic electrical engineering!!

Cheers,

All you require is a simple multimeter. Put that in AC voltage range and put the red pin in the bottom right hole and the black bin in the large earth hole of any socket in the house. If the multimeter shows around 240 volts then you have earthing.

Also your avr has 2 pin plug. It doesn't require earthing. Like @raghupb says, electrical engineering is being reinvented in this post.

Earth is not some magic black hole in this universe invented by some mysterious being solely for mankind to drain electrical noise. It has been invented by no less than human beings to provide a path for live (phase) current to the ground so that the ELCB trips and protects the frail human being from getting shocked fried or raised hairs as they show in cartoons.

I reciprocate that thought.

Thnx i have multimetre will check in 30 minutes. I dont even know if home has esrhing or not that 170 rupees plug i bought it showss no earthing. Can we trust 170 rupees plug

Don't relay on this .call an electrician and let him check with multimeter.
I m telling this out of my experience.my 6 yr old house has earthing issues which was not recognised .amp from india audio was also giving same noise later it got switched off .on advise f Amit I got earthing checked it was dead so I was forced to do complete new earthing and also it should be at an open space where water spills for it to get recharged .if it's covered with either concrete or slabs then it will die soon.

ok i replied on this amazon plug only and said no earthing to you. will try with multimeter can you again tell how to check with multi metre

May be it happens at some places in Haryana.

Better to get a electrician

 

[hardcore_gamer99]

ok i just checked with multimetre by placing red inside phase which is left bottom in my case not right and placed black prob on top big hole and showed 14volt. so earthing is there?

Left is neutral. You have 14v earth to neutral, which means your building earthing has high resistance. Right bottom hole is phase. You should be measuring between right bottom hole and the top big round hole. You should get high voltage between phase and neutral (which will be 14v less than the mains voltage). Ideally neutral to earth should be around 0 volts. This will give you the same voltage on neutral to phase and phase to earth voltages.

If your tester glows on the left bottom side then you have a screwed up electrical wiring. Check which bottom hole makes the tester glow. The hole in which the tester glows is the phase.

Is that adequate only electrician can interpret

Except calling a good electrician FM is doing all trials.

you can also try this by yourself, but place your multimeter switch to AC before trying anything (I think you know this). be careful
