Hidden TV mount will not lower

[Shirley M]

I have a tv mount that should lower behind the fireplace.  It will not move.  None of the circuit breakers seem to be flipped. Anyone have a solution?

Does it do anything at all? 

And knowing what brand/model RV you have would perhaps assist if one of us has a similar model.

According to her profile, she has a 2013 Sanibel 3400 fifth wheel from Prime Time RV, a division of Forest River. 

Am I correct that this is a powered raise and lower device? Does it seem to make any attempt to move or make any sound when you try to lower it? I would think that it probably shares a circuit breaker with the TV, so does the TV work? Also, did you open and then close each of the circuit breakers, or just look at them? It is very difficult to tell if  a circuit breaker has tripped with most of them as the handle moves very little but it must be moved to the fully open position in order reset it if it has tripped.

Every TV lift in an RV I have ever seen has been 12 volt powered.  This means the circuit will be a fuse in the 12 volt power panel, not a circuit breaker in the 120 volt power panel.  Check the fuses, then check the wiring at the switch and the motor for the lift.

Yes, I tried turning off each circuit breaker.  There is no sound or attempt to move when I try to lower it.  The TV works.

Thank you for your reins.

Thank you for the suggestion.I will try it out. There are a lot more 12 volt fuses than I am used to dealing with.

I have a 2013 Sanibel 3400 by Primetime mfg.  It is a subsidiary of Forest River.

Do you have a volt/ohm meter such that you can check to see if the lift is receiving power? That is a much better way than trying all of your fuses.

Regardless of the cause, if there's no voltage present (perhaps caused by a blown fuse or tripped breaker OR A BAD/BROKEN/LOOSE WIRING CONNECTION) even if you don't have a DC Voltmeter a cheap simple 12 Volt Test Light can help. You FIRST need voltage present and then a good working switch or relay to  make it operate.

Does the lift use a battery operated remote or a wall mounted switch? If it is a remote, try replacing the battery in the remote. It is also possible that the remote control board has failed and you would need to locate that to determine if it can be replaced. Many of the lifts use a linear electric actuator to do the motion and as mentioned are usually 12vdc. I just had to replace a remote control board on a system I use as the actuator would not lower but would raise up. I was able to reverse the wires to get the actuator to lower temporarily.
