Ok, have a really odd problem with my setup.
PS3 -> Sony STR-DG820 -> Sharp LC-70LE734U..
BlueRigger High Speed HDMI 15' between display and amp into HDMI 1
Cheetah HighSpeed HDMI cable between amp and PS3.
If I allow the PS3 to display full 1080p from the PS3 menu, when the PS3 transitions to the Netflix app, or I play a disc (BD, or standard) then, the display goes completely black, and the PS3 progresses no further until I do one of the following
* switch the TV from HDMI1 to HDMI2, then back to HDMI1
* temporarily remove the HDMI cable between the PS3 and the amp.
Never had this problem with my Samsung 46" display, with the other components being the same.
If I limit the PS3 menu to display at a maximum of 1080i, I don't run into this problem.
I have disabled the HDMI ctrl on the Sony amp, and the AQUOS link on the TV (I've tried it both ways).
I have also tried various combinations of cables between the TV, amp, and PS3, and all behave the same.
Not sure if it's a problem with the amp, or some other setting I'm missing. I'll entertain almost any idea.
