Hi everyone
I read this thread and I am facing the same issue. Purchased LG Led tv 2 months back with 2 HDMI port. It was working fine for first two months with Tata sky ...from 26th Feb onwards while watching HD channels the tv hangs or sounds automatically goes off. Most of the time suddenly tv shows no signal. Frequency of incident might differ but have tried changing the set top box, HDMI cable and all other things.
Have recently got the complete HDMI port changed in LG tv. Tata sky is not able to diagnose the issue.
Can someone please help what can be the issue. We are unable to see whether its Tata sky or LG problem.
