I have Model MR-17 JBL Marine unit built into a hot tub. For some unknown reason, I have lost power to the unit. Connections appear intact, but no power. The manual states it might be a blown fuse. How do I replace the fuse? Please advise.

Will a REM 25 remote work with the MR 15 JBL radio?

SOURCE: My JBL Marine Hot tub Sterio quit working suddenly?

JBL is at best a low quality marine grade brand of stereo. It is now garbage. I have worked on hot tub stereos for many years, PolyPlannar is the only one that is any good. If it was bought 30 days ago, where's your warranty?

• By no power do you mean you get no response from CD or radio out of the speakers when trying to use the radio? Should this be the case then I'd like you to check a few places.

1. First look to make sure the wires in the back are not broke or the insulation has somehow been negated.
2. Next is to check the power wires and ground wire. Look for an inline fuse anywhere between the battery and either power wires. One should always be installed to prevent a surge reaching the head unit so make sure to check for a fuse. Replace if blown with same size fuse, never bigger.
3. Remove the face plate and notice the reset hole (last hole on the left) Take a pen or other pointed but not sharp item and stick it into that hole and hold for 10 seconded. Then retry.
4. Make sure the contacts for the face plate where it hooks into the head unit are clean and don't have any grime buildup that would prevent any of the contacts from contacting.
5. Next you can try removing all power wires and wait for 5 minutes and re-connect. Sometimes this will also reset the unit.

• I know you asked for a manual. I don't have the exact one. I do have a similar one that I can offer. http://www.premiumleisure.com/Manuals/nov07/Hydro_Spa_JBL_Stereo.pdf
• Your unit was discontinued and not made for long and this may be a part of why the manual is difficult to find... for free anyway it is. I can say I don't need a manual to help you determine why the unit is not powering on.
• How are you determining has power but just not responding to the on/off button? A volt meter check to the wires perhaps at the back of the radio? If you get power to the wires at the back of the radio then double check your ground real well because if the ground is good then, at that point, the head unit is bad.
• If you perform all the tests I stated above and still no dice then the head unit is bad. There is no "code" for the radio so that will not be a factor. It's really a process of elimination.

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.
