CEC loosing connection over night (Alpha 4, Samsung TV, Rasp 1)

Help and Support Raspberry Pi

Hello,

I am running the Alpha 4 on a Rasp 1 and so far it runs really really smooth. One thing that bugs me:
CEC was working from the start. However, when I switch of my TV (Samsung) over night and keep OSMC running the next morning my CEC connection is lost and I can not recover it anyhow.

Any suggestions how to debug this or find the problem?

Thanks

I had a slightly different problem and that was that CEC did not work at all. Only after completely removing power from both my RPi and from the TV for a couple of minutes it started working again.

I did further research and unplugged all other HDMI devices to ensure that there is no interference by them:

I unplugged the power from my Samsung TV for 60 seconds and was able to recover the CEC after my rebooted my Samsung tv. However, later on after a longer standby time of my TV the CEC connection got lost again. Surprisingly the CEC signal came back, when I plugged in my TV settop box and booted it.

So, this is not really getting any clearer, but I can say that the root cause seem to lie somewhere between my TV and the Rpi. I also tried to use a different Rpi but had the same issues. Therefore I assume that it is no Rpi HW failure.

Any further ideas how to get this thing fixed?

Thanks
