Hi all. I just switched from Time Warner to Verizon Fios here in Queens, NY. the 1st time I tried to connect to my SB AV I receive the message "Weak or no signal detected". I went through the set up assistant and I can turn the cable box on and off and change channels but no A/V. My connections are fine and have checked all my cables and no problem there. Using the composite cables no HDMI cable.
