Q700A Soundbar Buttons not working (Power/Volume/Source Buttons on top of soundbar is not working)

Samsung Q700A Soundbar buttons not working on Press/Touch

I am able to control the soundbar via Remote. But the hardware buttons not working. It's connected to Samsung 65"  BU8079.

Tried resetting both my TV and Soundbar, but It doesn't solve the issue. 

Any Suggestions...

It might be the contact problem between the cable and the connector inside of the soundbar....
