AV7000
FIRST GENERATION PLASMA FUJUITSU - 
DVD PLAYER PLUGGED IN CDV ON AV7000
VCR (yes a VCR) plugged into V tape and the cable box wired throught the VCR
I also wired cable box into CDV so take vcr out of loops to narrow it down. 
I turn the system on i get sound from the cable box but no video. i see "static" lines on the screen 
I tried a new input on the av7000 but still no video. 
any ideas?  
the tv when i hit menu on the tv remote works. so the "tv" is working.
