When I first ran this cable (50') from my projector (JVC DLA-NX9) to my AV processor (Marantz AV7704) through the ceiling, it worked beautifully. But the next time I powered it on, no signal, but wiggling the cable made it work. The next time after that, intermittent picture, but then nothing. Now I'm wondering if it's kinking where it turns 90 deg from the wall to the ceiling in the front of the room? At the back of the room where the projector is, there is no tension, but in the front of the room there is gravity pulling the coiled extra cable. I looked and it didn't appear strained, but the AVP is on a pullout drawer so tension can change.
