I agree that ground is the first thing to check. If the ground wiring isn't good between the TT and TV, you'll have intermittent issues, because the grounding will occur through the hitch.
Get close enough that you can connect the 7 pin, but don't hitch up so there's no direct contact between the TT and TV, just the 7 pin. If the cabling is good, all the lights and brakes (have someone near a wheel listen for clicks as you work the manual control) should work.
