Jbl marine mr-17 all funtions are frozen

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.

If you unplug the BLACK wire LABELED remote control, this controls the rear radio controls on the boat, then make sure your power is off and re-plug it,this should fix your problem. I experienced the same but the head unit only stayed on FM not CD. I have a question for anyone reading this, has anyone hooked up an amp to this head unit?

The JBL MR17 transom remote hasn't worked in years. I took it all apart and cleaned it but everything looks good. I will definitely try the reset button to see if that works. CD player wouldn't eject my CD until one day the CD just ejected itself and then out came a second CD! Problem solved. Then I tried playing a CD I burned. It loaded and indicated it was spinning but it wouldn't play. Turns out I ripped the music in MP3 format which the JBL MR17 doesn't recognize. All I have to do is change the ripping file format I'm using. I tried a prerecorded CD in the player and it worked just fine. Just putting this out there in case it helps someone with a similar problem.

Hi Folks,

I have the same problem with my JBL MR-17, it is stuck on an FM station. Can you give me any instructions or advice as to how to dicsonnect the remote plug on the back of head unit? It is really stuck together and I cannot get it apart. Any help is appreciated.
Thanks, RB

I have a MR-17 with three remotes and had the same problem. I found one of the remotes was plug-in in the wrong direction. Yes you can do that. I pulled it, realigned it to the direction it should go in and all worked.
