That guy is a clown. I would expect him to go through some sort of protocol on your t.v. I have an input on the back of my LCD for the tech. If the t.v ever needed to be serviced I would expect him to use it.

Hey, the guy might be that good, however if there are multiple things wrong with the television how would he know without doing some sort of test.

Good news, atleast you are covered and it will not cost you anything:). Imagine paying for a service call from that tech and all he did was turn on the t.v!

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
