About what settings do you have on your Prodigy P2 Controller when all set up? I adjusted mine up and down the scale and could not get one sliding tire when applying the manual lever. It says to start at 6.0 and then adjust up or down to just short of locking the brakes. I have the 2310H with dual axles which is the equivalent of the 2209T but a maybe bit heavier.

Have you tried the other button on the controller? It gives you 3 settings for "power boost". I have my controller set on 8.0 with the #2 power boost setting.

When you push the manual lever do you get any trailer braking at all?
That size trailer should not require a power boost setting. My 2209T is at 6, I think and I have good braking, with no boost. A boost setting causes a very abrupt stop. My 2195T was about the same setting.
You may have a ground problem between the trailer and the TV.

I think that I have a ground or connection problem like you say. Winter may have take its toll on the truck's socket. I had better get to work on it. I had plenty of braking before with my old controller, and the Prodigy appears to functioning OK. I do get some breaking, but it is on the weak side.
