OK, I've made sure both ends of the cables have slack and Deep Color on my PS3 was turned off already.
I too am wondering if it has something to do with the PJ warming up and changing something within the connector and the reason being, is yesterday, I came home fired up everything and played some COD. About 20 minutes in it hiccuped. After it played fine until i turned it off. I came down, made some dinner, posted up on here to create this thread, then after dinner wife and I decided to go up and watch a movie. Fired everything back up (probably only 45 mins in between COD time and movie time, so not much cool down) and started the movie. I even had the foresight to start a timer on my phone to try and determine if it does cut out at a specific time period. Well, we watched the entire movie without anything happening. So I wonder if it does have something to do with the projector coming up to temp or something? I will double check the cables, and report back if anything else changes.
Honestly, in the end this isn't a make or break issue for me. I can certainly deal with it, so long as it only happens once per use and at the beginning of use (I say this primarily because I've already ran the 30' cable through my attic, down the inside of a wall and into my setup and don't really want to buy a new cable and redo all that again haha).
Thanks for the responses!!!
