yamaha Avr with electric current on body

I purchased a Yamaha RXV-685 in June 2020.The screws,usb port,aux port or the insides of the vents of the Yamaha receiver is having small electricity.Its not something that will give a shock but yes it does give a tingling sensation if touched.So naturally i took a tester and when i tested i found the small current.Its not there on the whole body probably due to the paint.

I thought this could be a defect and hence called up the seller and he checked his personal device and also some other Yamaha AVRs and found the presence of this small residual current.He wasn't aware about this till i reported it on my device.

i just need to confirm for peace of mind if its only certain AVRs or if this is there on every Yamaha AVR which may suggest that its as intended and not actually a defect.

Please find the attached photos.Could Indian Yamaha users please confirm if this is the case with all their AVRs?

Please note that the BODY doesn't have any current due to the paint coating but only the screws and any metallic part like the inside of the vents and the usb port and if u connect an AUX and put a tester to the other end of the aux cable u will see this current.

only indian yamaha users could you please check and comment?

Sounds like you have a grounding issue, which I would resolve as quickly as possible, before it damages some of the boards.

so why is it that the seller of this device also has this issue on his other AVRs.my only question is,is this a defect of the indian receiver.other than the diy grounding workaround would i need to gwt it repaired and any repair will it mess with the quality of a 1 month old device?

It may or may not be an issue, but please confirm if you measured voltage or current. I know you wrote "current" but I want to be double sure. Either way, how did you measure it, and what was the measured value, in Volt if voltage and A, or mA if current, obviously. Also did the value change it the unit was power off, but still plugped in, versus power on, that is when you actually using it to listen to something.

i will answer one by one:-
1.first i experienced a slight tingling effect wen i happened to move the receiver while it was playing.
To confirm i took a screwdriver tester and tested all over.only on all the screws and inside of the vents and on usb ports and the aux and headphone port did the tester light up.Thats how i arrived at the conclusion its current.
2.i dont have any device in hand to measure it still.if smthng needs to be checked i am more than happy to purchase it and give it a go.just let me know wat i need and how to do that.
3.when the unit is connected but the power switch is off--->no issue.tester doesnt light up

when power switch on and the receiver in standby mode-->yes there is current

now switch on the receiver using the remote.now the tester detects current everywhere.

just for info.watever be it but isnt it abnormal to even have leakage current on the screws and metal prts?

Is there a difference in phase / voltage / grounding between the Malaysia market and your geographical market?

That's surprising. Here in the USA they usually contact you, via e-mail, with more detailed information or request you contact them via a phone to their Tech Support Center.

How far is the closest Yamaha service center? Reasonably close by?

I can't stress enough that you unplug it before it does some internal damage to the boards and voids your warranty.

Good luck.

I also wonder if the service level from Yamaha is partly due to current Covid shutdowns?

Im curious to know if the vendor for Amazon is indeed an authorized dealer. Judging by Yamaha's response, I'm leaning towards no.
