I have a 2012 Dutchmen Bunkhouse that has an outside stereo. The stereo is broken...that is the light is on as if it is turned on but nothing is displayd on the screen, and it does not work. It ha...
Is what you have on the outside possibly a control for exterior speakers and not a "stereo" in the sense that it has a radio, a disc player, or a tuning selector?
Can you describe it better? Is there a brand name on it?
If you just want the light off, I'm pretty sure you can unmount it from the exterior and remove the connections to it.
