@me_saket Yesterday like viswanath tata sky also send 2 trainers along with 1 sr.technician to my house and they said me that there is problem on your dish antenna,so I change my dish antenna still I am not geting good picture quality as earlier.I compalaint to ceo they told me that they will again sent the technicians tommorow.I ask the technicians the problem is due to heavy compression or what?They said no.There is no such reasons for bad picture quality.So,I want to know from Viswanath that What was exact problem with his connection?Why he got bad picture quality?What action taken by technicians in viswanath's tata sky connection by which he got back his good picture quality as earlier?.
