So I bypassed the switch and indeed, the even tp channels on 119 were still out.
However we noticed that they come back in in the evening. In fact, after a few weeks of observing, when the temp. outside gets to 75-80, the even tp channels come back.
Now, I have a Superdish with 110/119/105. I don't use 105. Any chance I can retask that 105 LNB to the 119 position? Is 105 the lone outside LNB, and 110/119 the double LNB? Can I replace the 119 LNB myself by buying a new one on Ebay/DishStore, or does it have to be aligned or activated after installation?
I don't want to bug Dish to do the repair (and possibly have to buy a LNB from them) because as soon as FIOS is available, I'm likely going to jump ship.
