picture would help

Here are some pics... not sure if it helps

oh the power plug, i would take the power supply into radio shack so they can match the pin size but that has an rf remote, i have mine double sided taped to the back of my tv and the remote works perfectly plus i dont have to stare at the lights at night

I tried that and my remote doesnt work....

What is the model number?

Directv H25 Power Supply 

c31 700

Mount the mini on the wall then the cable will run up or down

Remotes work ir and rf you need to go into the menu and change it to rf. Heck sometimes my wife changes the Chanel Lin our room and it reaches to our loft and changes what I’m watching 

You need an RC6XR remote to use RF.

Order this: Wall Mounting Bracket for DIRECTV H25 Receiver (H25MNT) (solidsignal.com)

also you may need to add this 

DIRECTV RF Remote Dongle Adapter For The H25 Receiver (H25RFANT) (solidsignal.com)

@shannon02 mt RC73 does both

constructive - the RC73 won't work with the C31 in RF because the C31 uses the"old" RF protocol
