I recently changed my freedish set top box as old box is not working. when i was blind scanning for Channels I did not get any channels. after that I switched off FTA Only in the setting and Now i was getting signal and channels in Horizontal frequency of Sundirect TP , no signal from Vertical TP. As dd free dish Tp also Vertical, I am not getting the same. What might be the issue, i tried changing Skew angle of LNB but again no signal of Vertical Tp. what might be the issue. Is LNB fault or position of dish itself. Also my LNB is nearly 6 years old.
