I can't find my manual. Up until last week I had the HBO cable box running through the hs-u430, well i gave up the HBO to saves $20.00 a month. Now with the Coaxial Cable going to the VCR I can only get Channel 2 to14...when I go above 14 all I get is a Blue Screen and I'm only able to go to Channel 69. What do I need to do to watc all those programs above Channel 14. Sincerely, Jack
