Did you guys use a Cal-Lab lightning isolator with your previous decoders? I was told by my installer to bypass the lightning isolator when connecting the coaxial cable to the new decoder (to prevent/minimize signal loss I suppose). Hence, my other audio/visual equipment are at risk from lightning strikes to the satellite dish at the moment

Anyone with experience in this?

Having some issues with my HD channels. When I select a HD channel, the sound comes on but there isn't any picture - the screen is blank. Changing channels back and forth do not help. SD channels are okay.

Decoder problem?
