TV and PRE/PRO turning each other off when HDMI devices are connected together
This CEC stuff is driving me mad!! I have a month old TV 4K Sony 75" 940E, A month old PRE/PRO a NAD T187 with the 4K VM3000 card and a 2 month old OPPO UPD203. I also have a 1080P Comcast box hooked up to one of the inputs on the NAD. After weeks of frustration, I have turned off Sony's 'Bravia Sync' and also turned off the HDMI CEC settings on my NAD as well as turned off the CEC setting on the Oppo player. When turning on the TV with the remote, if the NAD is already on, the NAD turns off!!! Grrrr. Why!!!
Also if turning on the NAD with it's remote, the TV turns off if it was already on. This is frustrating as well as screwing up the HDCP handshaking which leaves me with blank screens every time I try to watch a little TV. These 'patterns' aren't always consistent but consistent enough. Very aggravating. These haunted 'operations' where one device turns off another device when it powers up, continue to happen even with CEC turned off in everything. Haunted House?? Friday the 13th? This weird stuff including 'digital snow' on the TV screen when the TV first powers on intermittently has happened from day one!! Any ideas??
I am considering hooking up the Comcast box with the HDMI cable directly to one of the TV's HDMI inputs instead of hooking up the Comcast box to the NAD. The audio from Comcast will be from the TOSLINK fiber optic FROM the TV back to the NAD. I may do that tonight. That toslink fiber optic cable is already in place and is used when I watch internal Apps built into the TV. (Amazon, Netflix,Etc). It works well. It should give me sound from the TV if I plug the Comcast's HDMI cable directly into the TV.
I may also connect the VIDEO from the OPPO directly into the TV and the AUDIO from the OPPO with another HDMI cable to the NAD. This way, there will be no HDMI cable from the NAD to the TV. All video sources will connect with HDMI directly to the TV and not go 'thru' the PRE/PRO. Seems like a safer way to hook everything up.
It should solve the CEC turning off problem as well as the intermittent digital snow problem. Does this sound prudent to essentially bypass the $2500 NAD PRE/PRO and have no HDMI cables between the NAD and the TV? This could solve the one device turning off another device when it powers up as well as the intermittent digital snow on the TV screen (HDCP handshaking gone wrong?) I have changed HDMI cables numerous times and the problems simply wont go away. I'm convinced it's not the HDMI cables as I am using high quality, low distance cables. The same problems continue after I change out HDMI cables. Grrrrr!!
Any thoughts?? --Greg--
