So I conclude that servant maid has touched Kumar's stb.
Kumar both Signal quality and strength are O?
Very clever. In my case, the connector had become loose. The instance of the high tech home was reported in a newspaper article.
You may not believe this, but this story is true. We had supplied a machine to a customer in Bangalore, and within a week of installing we got an sos that the machine was not switching on. I did send a telex(!) to the customer to see whether the fuses were OK. He, like you was flippant, and insisted on a visit as the machine was under warranty. Well, it turned out that the maintenance man had removed the main fuses to prevent unauthorised people from starting the machine, fell sick and did not report this to anyone.
It is better to eliminate simple and obvious causes, before trying high tech stuff.
Sarcasm does not get you anywhere, young man!
I will let you to be your self and refrain from responding.
