Samsung JU7100 : BN96-35817Hyes
from the description on the Ebay item I bought
BN96-35817B One Connect Mini WITH CABLE
Samsung is sending me another unit under warranty
However...as I said before I am 99% sure the issue was with the Denon receiver
and now that you mention it...
I had done a update( prompted by the TV)...and then I had issues with the TV not wanting to turn on when connected to ARC
But again...for the last week it has been fine
The BN # on my OCB Mini: I assume the B versus the H means you have an older version.
After reading through the Forums, and all the ARC issues. Tried once. Got it working. Then intermittently, and finally opted for the Optic Connection instead, and have never looked back.
