I have a CD / Radio in a Jacuzzi. I opened the panel a couple of occasions with no problem and on the last one the Radio / CD does not work. There is power to the device but although I can open the CD for example the front does not light up and shows no sign of life. There is no reset button. I have no user manual. Can you advise where I can get a user manual? I have been on JBL's website, but it was no help

Hot Tub with working JBL MR4 was bought, moved to my house...wired up tub, lights all work fine buuuttt the JBL MR4 doesn't...power is to the 110 box under the radio, it has been re- connected according to the manuel and previous set up... the faceplate totally lights up in all possible configurations so you can't read the display...can read USA and countries on top, the CD area I can read and 2 sets of black increment bars areon each side of the faceplate display...only button I seem to get a response from is the power on/off as it lights up...as i turn the vol it blinks with each notch display on then off...I disconected faceplate and reset button , no effect...repowered(no battery seperate hookup as this a hot tub not a boat,red and yellow are wired together).????any ideas on whats wrong???? CD goes in and out???? [email protected]

Because of that moisture it may have fired the lighting connection inside the unit, does it produce and sound?
