Had to resynchronize programming today - Programming returned but now the picture freezes after about 40 minutes of play. When I go to Channel info and change channels - I get a black screen - I turn off receiver and turn it on again - The receiver goes through normal 1-5 search - downloads programming and everthing comes back - watch TV fo 30-40 minutes the same senario repeats itself. It has been very cloudy today and the signal was down to 60% - normally 76%. Maybe it will improve tomorrow. I am not plugged into a phone line because I am in my motorhome - Power is on the receiver about 2 hours per day - not hooked up to A/C - using generator while watching TV. Have internet and skype phone. It may improve tomorrow - who knows - with Bell TV! Any suggestions or info would surely be appreciated. Thank you.
