Here's my current setup: Harman/Kardon AVR 1700 Receiver, Xbox 360, PS3, Cable Box. Connected to Polk Audio RM705 home theater speakers. All running to a Viewsonic Pro8200 projector, ceiling mounted and thrown to a 100'' screen.
My issue is this: I sit on my couch, which is about 4-5 feet from the receiver and 3-4 feet under and in front of the projector. Everything works great...until I stand up between the projector and the screen. When I do stand up to leave the couch, the projector cuts out for 1 to 2 seconds, goes to the Viewsonic title screen, and then returns to the source. If I connect to the source (i.e. Xbox, PS3, or cable box) directly to the projector, I cannot get the projector to cut out when I stand up and down. However, the once I connect the project back to the receiver, it cuts out once again when I stand up. Additionally, I need to be sitting to the spot closest to the recieveer in order to get it to cut out and it will cut out regardless of what source I use.
It appears to be something to do with me making a movement (such as standing up) when seated close to the receiver. Anyone have any idea what is going on here? Anyone every experienced anything like this?
