Does the TV have 2 prong plug or a 3 prong plug?

Are you using a digital Voltmeter?

Try this with a test lamp with a 25 Watt bulb.

It is normal for 2 prong appliances to sometimes have a small amount of
leakage. A digital voltmeter will respond and show this leakage.

If this is a 3 prong applicance then something is very wrong and maybe
dangerous

And if it is either 2 or 3 prong and you can see any light at all of a
25 Watt light test bub then something is VERY wrong and it is VERY
dangerous.
