I purchased my Samsung Smartv UN65MU7000 3 years ago, and haven't had any problems in that time. Recently, my original Samsung remote (that came with the tv) failed, so I ordered another. I was able to successfully pair it with the tv, and it also detected my Blu-ray and sound bar. Unfortunately, it cannot successfully detect my Directv receiver, so therefore I am unable to control the channels. It sees the HDMI connection, and the last channel it was set to can be seen, so I know it it is successfully connected to the receiver. Problem is, since it cannot detect the Directv receiver, I am unable to use the channel selector. I have ordered another remote, and it fails the same. I have unplugged bothe tv and receiver. Unplugging and reset both, changed the HDMI cable, and verified all my updates are current. Any ideas? Thanks
I'm sorry to hear that, can I have your current software version number? Also have you made sure to do the following?
Press the Home button on your TV remote to access the Home Screen. Using the directional pad on the remote, navigate to Source. When the selector is placed over Source, the Source menu will appear. Press UP on the directional pad to access Universal Remote.
Select Universal Remote on the Source screen. Next, select Start and make sure the device you want to connect is turned on. When your desired device displays, select it. Follow the on-screen instructions to complete the setup and register the device. The instructions may vary, depending on the device type selected.
Your TV and the remote will memorize the external device and its connection port (HDMI 1, HDMI 2, etc.) to make controlling everything even easier.
Occasionally, the device may not respond after it's registered. To make sure the connection is made, you need to re-register the device.
