i had the same problem before June. But for internal, we get outsiders to settle. Old house, although previous 20+ years no faulty, but suddenly lots of disconnection. It is those internal cables inside the cement. Once we pulled new lines, we called TM to come and they also pulled new lines from tower outside the house to our house, then all problems settled. The outside cable is depending on distance, but a kind TM third party was helpful to get the cost down.

So that's just my case for your reference. I had 2 problems, internal house wiring, and also external from TM poll to my house.
