Hi,

Initially, have you tried a full hard reset? The reset button is at the panel at the back of the faceplate, bottom left side. Of course doing so will also erase all presets and user settings & configurations.

Additionally, pls verify that the multiple contacts pins are clean, free of corrosion and makes a positive contact with its mate at the rear of the faceplate. If the unit is used in a salty environment, it may be necessary to manually scrape of whatever blue green build up develops between the connector pins and the plastic insulator. You can try using an old toothbrush and WD40.

Further to check are:
1. the red, yellow and black wire are tightly connected where they are supposed to be connected. If the unit is used onboard, it might be to your advantage to likewise check the grounding system;
2. one of the rear connector is for a remote, pls likewise check that none of the pins are shorting and no presence of any corrosion.

If problem persists, it may be necessary to seek the services of a qualified professional as this involves opening the unit up and tracing the circuitry of the logic/controller circuit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I have the exact same issue. I have swapped with two identical MR17.2 radios and swapped out the sirius receiver. No change. I even bought a remote thinking I had to have a remote installed to get it to work...still no diff. Have you ever found a solution?

I have the same model stereo in a brand new hot tub that was having the same issue. To fix it all u need to do is pull the front cover off to access the pump controls and in there you will find a black box where a power cable runs yo the stereo. There are two screws that open a little door in the black box. In there you will need a small flat head screwdriver to move a redswit over to the 110 volts position. Turn the radio on and it should work. That black box just controls the power to the stereo.
