Anynet/HDMI-CEC and ARC not working

Hi there,

I have this problem for over a month now.

I have a Samsung TV model UE49MU8005 connected to a Pioneer Receiver model VSX-LX302. Everyhting is well connected, as far as i know, TV firmware is 1210.8.

Tv is connected through a recent HDMI cable (UHD, ARC, etc etc) from the ARC output of the receiver to the ARC input of the TV (HDMI 4). Anynet is on.

When I disconnect the cable and connect it again, it starts identifying the source on the TV and it always says "unknown source" so i have to manually configure the tv remote. After it detects my Receiver, turns it on and off ok, and finishes the connection. Everything seems ok. But the problem starts here:

- The sound does not come out through HDMI from the TV if I select an app from the hub. Neither it does if it's connected to the antenna of the tv.

- I have sound from the cable box and from a PC both connected to the receiver.

- The receiver has CEC on but it the sound is not there. When I disconnect the CEC on the receiver and connect it again, it starts searching for CEC devices but the answer is "no CEC device"! Although the TV is connected of course..

- Anynet stops working too, it doesn't control my receiver when this is happening.

- This bug goes on and off. It works sometimes, other times it doesn't. It seems that theres is some problem in the TV that disconnects automatically HDMI CEC, and then it just doesn't come back.

- I changed cables, update firmwares, disconnected everything and waited, then connected again, called Samsung support and they just don't seem to know what I'm talking about... The problem always persist.

Frankly, I'm considering returning the TV. It's new and for the price it should NEVER cause such hassle.

This is about something that should work perfectly and is not doing so. And it seems that everyone at Samsung knows the problem exists, they just don't know how to solve it... (according to the countless discussions about this topic, at least at the US community..).

Please help!

Regards

Thanks Nomis! Obviously disappointing to hear that a new AVR with modern HDMI connectivity would still experience the same issues with Samsung TVs, but it helps manage my expectations.

 

I guess that leaves me with three options:

 

- using HDMI ARC and disconnecting everything from the power source once a day (which is what I am doing right now with my old Denon AVR, but it's a hit-and-miss)

- using an optical cable instead of HDMI ARC (supposedly stable!?)

- connecting the sources - eg Mac mini, Apple TV etc - directly into the AVR and using the Samsung TV only as 4K monitor (and avoiding the unstable ARC technology)
