hi, ive been up and running for probably 3 years untouched(other than yearly codes) and about 2 weeks ago i noticed some channels were low signal and quality and channels that did work, now say no signal. ive replaced lnbs, repointed the dish(getting 90s for S&Q), and rescanned 119 and even when i rescan im only getting 116 channels so many are missing for me. ive tried playing with tp's, and so far no luck. channels i want are HLN, discovery health, E! and all are missing anyone else had this problem?
