Our family lake home took a nearby lightning strike. The strike took out all electronics plugged into a 1985 power strip: A router, cable modem, an old Sony B65 DirecTV receiver. We immediately replaced all the electronics (and we have an adequate surge suppressor now) but the Directv channels came on at first but soon, channels started disappearing. Finally they were all gone (ext. 721). Resetting the receiver only yielded "searching for signal". The lake home is two hours away. Trying to solve this from home over the phone with my elderly parents (who are testing the components for me) is a challenge to say the least. I figured I would replace the final two things that it could be; the old dual LNB on the dish and the multi switch. I drove up to the lake home and plugged in the multiswitch and everything started working immediately. I did not replace the dual LNB thinking it was not necessary. It worked for 9 days without a hitch. The lake home was vacant for 5 days and when my parents returned, nothing. A reset again brings searching for signal. I'm looking for suggestions. My parents are planning on having cable turned back on (I fricking hate cable!). DirecTV was working there flawlessly for a year and half before the strike.
