That's an odd effect - not one I've seen with my 885 and Sony KDL-40W4100. The length of that Monoprice cable certainly creates the potential for a problem, but I'd expect it to be all the time rather than intermittent. The description fits with a problem with a handshake error. How is the video processing set on the 886 for that input? If you set it to bypass video processing on the PS3's input, I wonder if it would still happen. Or, if you've already got it set to bypass, I might try setting it to 1080p.
