TiVo IR Port not getting signal

My friend gave me his old tivo. When I opened the box because I heard something rattling, I noticed the IR Control cable was disconnected.

This is the cable coming from the IR sensor in the front to the mother board.

I plugged it back in, powered on the tivo. The TiVo works fine, but i cannot get any response from the unit with the remote.

The remote lights up and to test the remote, i programmed it to turn on and off my TV.

It has brand new batteries.
Its not a remote where you can switch tuners.
On the front of the tivo, the red led doesnt display as if it were getting signal.

I am thinking it has something to do with that cable.

 

Looks like I found the answer to my issue
