I'm sorry for the newbie question, and I apologize if this is not the right thread, but I'm having a problem connecting my surround system to the 70le632. When I first power on the TV and surround system, I receive video on the screen for about 30 sec. After that, the screen goes black. The audio still goes through the surround speakers. The TV remains powered on. Here is my setup:
DirecTV HD-DVR-->HDMI-->Receiver (Sony STR-DG910) SAT in HDMI port
Receiver HDMI out--> 70le632 HDMI 1 input port
At first I thought it was miscommunication between Aquos link and the Bravia Sync on the receiver, but I still have this problem with both Aquos link and Bravia Sync turned off. I also tried switching the HDMI input port on the 70le632, but to no avail.
When I don't use the surround system, the TV works perfectly when I connect the HD-DVR directly to the HDMI 1 port on the TV (with sound only going through the TV speakers, of course). I also tried the identical surround setup (with the same HDMI cables) with another TV (Sony), and that works perfectly. Is there a compatibility issue between the Sony receiver and the Sharp TV? Would another receiver brand work (Onkyo, Pioneer, etc.)? Am I missing a connection? Could a TV setting cause the issue?
I called Aquos advantage, but their rep couldn't identify the problem. I thought I'd turn to the real pros. Does anyone know the solution to this? I'd greatly appreciate any feedback.
