No power at outside stereo/ tv.

TV works, outlet works, just no power at the stereo control box.

What is the year and model of your unit?

I have a stereo/radio/DVD player inside the RV below the living room TV.
Are you saying you have a separate radio/stereo on the outside somewhere, maybe inside a storage compartment?

Our 2014 - 3850FL had an outside compartment with at TV and Stereo/DVD player. The stereo operated off the 12v system. Look for a blown 12v fuse in the main fuse box. Also, you can remove the 4 screws at the corners of the unit and pull the unit out of the wall to see if there is an in-line fuse. While you are in there, undo the folded FM antenna and use some screws to stretch the antenna inside the void space. You'll be amazed at the improved radio reception!

Thanks much, I'll check the fuses. Yep, have a 2014 3850fl .
