Hi,

I recently bought a mini Hifi system which has a metal casing and came with
a 2 pin power plug. There is a tingle sensation whenever I touch the casing
accidentally.

When I connect it to my TV one day and found it has no more tingle
sensation, I discovered it was because it was grounded via the TV as I also
have my PC connected to this TV. I used a multimedia to verify it was
indeed connected to ground.

Can I connect it to earth ground to eliminate this tingle sensation? Or it
should be left floating?
