Don't know if it's related but I am on HD STB and something like that happens on my STB too. Sometimes on switching channels screen goes completely blank for 3-4 seconds. On SD STB there was no such issue
Review of HD PVR STB + Super LNB after using it in Rains:
Hi all, as ur aware rains started here from monday. The cyclone effects like strong winds and very heavy rains are being felt here too.
I am using HD PVR STB along with Super LNB, and i have made certain observations on its working (reception) in these conditions.
The Super LNB works flawlessly during heavy rains also got to see it works even in very heavy rains also with the MER showing 5-6 dB that is 0% SQ.
But during heavy rains and even very heavy rains if its very windy or very dark clouds present the STB looses signal for approx 5-10 mins and LNB automatically stabilizes itself to regain signal. Earlier when i was using HD STB with Quad port LNB i remember signal used to go in heavy rains also for similar time.
Overall i am happy with the performance, monsoon is yet to arrive here after which I will again observe if i find anything different from that of now taking into consideration the current observations were of cyclone effects that are bound to impact the signal.
