[Resolved]  Tata Sky — set top box restarting every few minutes

The hd set top box keeps on restarting every few minutes. It's frustrating and annoying. I am paying money for not being able to view the tv. I have complaint to tata sky customer care multiple times. But haven't got it resolved. Few years back the set top box stopped working suddenly. They replaced the set top box. I want to believe that this particular hd box has some manufacturing defect. Hence creating problem. I had the normal set top box earlier or more than 8 years. But it never gave me any problem.
