I have an AKAI 42" monitor hooked up through a RCA HTS 1000 VCR (signal) and a Silvania DVD Surround Sound System DVC 840 F (sound). At first all was well. Then I lost WPIX (Channel 11 in NYC), then Fox (Channel 5 here) now today during the golf Channel 4 WNBC started getting lines through it, then going on and off and then disappeared (blue screen)...What happened...What can I do...Can anyone help me ????Thanks, Nancy
