Recently installed PureFibre with new Arris VIP5662 PVR. Managed to get installer to drop off optional Breakaway cable (din > component + rca audio). I need this to have RCA audio into AVR for patio speakers (analog only). The PVR -- through component cable -- is suppose to send video signal to Pioneer flat panel TV (as long as HDMI cable is also not connected -- it's one of the other). But when I reboot PVR, the initial screen splash (3 dots) does show on TV, then it goes blank and PVR shuts down. Tried this several times but fails with each attempt. HDMI works ok though. But I need the component cable option. Is there some instruction that I'm missing here?
