I hooked up my new phillips dvr yesterday and everything was fine all day. Go to see a movie and come back and there is no sig on 2 tuner. Reset everything and then only recieve half of stations. Give up go to sleep wake up and everything is fine again, any hints. I've got a round dish with a dual lnb that goes into a multiswitchwhich slits out 4 ways. My signal is always at aroun 93 so it is quite good. Thank you for any help.
