I've been trying to track down this problem for months. The CD player plays for a little bit(few seconds) then gets all static.Sometimes it won't play at all. This is whether we are under power or just sitting in our slip. I've tried CD cleaners and replaced the unit three times. The FM/AM band play fine.When the volume is increased on the CD side the static gets worse. I'm thinking that somewhere I have some corrosion on either my speaker leads or maybe even the powersource. I DON'T want to have to pull new wiring through since it's a bear to fish this stuff around. Need some help. Thanks Paul H S/V Linda Belle 95 H26

Try turning other things off one at a time. You may be able to isolate the thing causing this. When my battery charger kicks in, my stereo gets static. Paul

Check voltage
Check the voltage at the CD player while it is operating and ensure that it does not fall off. It sounds like a semiconductor failure in the CD that fails as it warms up, but you say that you have replaced the CD unit. Possibly a loop-back problem in the amplifier/speaker wiring. Are the CD and AM/FM in the same box? Is there an external amplifier? Does the static slowly override the music or does it suddenly replace it? Did it ever work correctly and if so, did the problem start in association with a change to the components or wiring or power supply?

chep cd player
I also have a problem with my cd player after only a couple hours of playing the reader is intermmittant and fails to work. So I have resigned myself to having only fm.

CD Player Problem addendum
Victor, sometimes it plays fine then slowly the static over rides the music.Or sometimes after it's warmed up all you get is static. I noticed when I had the unit out it developed a lot of heat in back. Since this is installed in a plastic compartment and pushed up against the speaker wires could this be a problem. But I ran the unit outside of the case and it still had the static. As far as the amplifier is concerned I thought it was part of the CD player.I f it is seperate I don't quite know where to look. I bought the boat from an individual. The wiring in back goes directly to the speakers. The voltage was checked last weekend and seems constant. The first unit I had was an AIWA then replaced it with a Sony. The unit worked great at first(for about six to eight months) then gradually the problem arose. Paul H S/V Linda Belle 95 H26

Hey Pablo...
from what you have described, the stereo itself is bad. It's impossible to tell without the right test equipment, but some little component on that PC board has likely gone thermal on you and the only way too fix it is with a soldering iron. If you can't get it replaced under warranty, you can take it down to an authorized repair shop and get an idea of what it will cost to fix, but most likely you'll be better off just chucking it and getting another one. I go through a stereo every year or two on my 'wheeler truck; it seems the vibration, shock loading, heat and moisture kills them pretty fast. And, when you consider all the features and power of a stereo that you can get at Wally World for $150, it doesn't seem too bad for having great tunes. Jeff

Gord May is correct.
If you FM/AM band sounds fine yet your CD player has static then your speakers and their wiring are fine. The problem is within your CD player. (Or perhaps from the CD player to your amplifier. More later.) However, you stated that you had changed the CD unit three times. I find it hard to believe that three units, unless from the same factory time unit would be bad. From the information provided, I deduce that the CD unit is separate from the FM/AM and the amplifier. Given that three separate units would unlikley be bad, I would suspect the wiring, or more likeley, the connectors between the CD player and the amplifier. Again, check the connectors, always a trouble point, between you CD player and the amplifier. Unscrew them and inspect the solder joint or the crimp. To reiterate, having replaced three CD players it is unlikeley to be the player but more likely the connection between the CD player and the output of the sound since wires seldom fail.

CD Player Problem question
Hey guys, I don't believe the unit has an amplifier. It's just hard to believe that three units would all develop the same problem. One of them was an AIWA the other two Sony's. I suppose I could pull it out again and take it to a local service center but as one fellow put it the cost of doing that may outway just getting a new unit. Would corrosion on the power portion of the wiring cause enough of a drop to not fully spool up the CD but enough voltage to run the radio? The CD and AM/FM are all one unit.Sometimes it will play for a while if the volume is not put to high. I checked the unit out with where I bought it and they said this receiver does not require a seperate amplifier. Paul H S/V Linda Belle 95 H26

power loss
I think your on the right track now, I've noticed at times when one of our batteries get to a certain point (loss of charge) that the CD player will start acting up, radio would most likely play for days but CD players take more power and refuse to work when its not getting what it needs. sounds like you need to take a long look at the wiring and have as few connections as possible between the CD player and breaker/fuse. Also not sure about the service center near you, but the one I used in the past checked out the player for free before work continued.

Too much speaker for too little amp?
Is it possible you are trying to drive too many speakers at too high a volume level for the capacity of the built-in amplifier and frying it eventually? Is one of the speakers shorting and drawing too much power? I am not an expert on the numbers involved in these calculations, but I suggest you consult someone who is. The people that supply higher end car audio systems usually know their stuff. I am assuming you are using a 12 volt automobile CD/FM integrated unit connected directly to the speakers, just as it would be in your car. If FM continues to work perfectly, then this is not the problem.

Victor,Didn't get a chance to get to the boat this weekend. Next weekend I'll get down and take a look. You and Ken have given me some leads(no pun intended) to follow. I noticed when I was connecting the unit the previous owner had one positive power line coming in and split it to make the dual plus connections. I think if I disconnect that splice and run a line directly from the unit to the plus terminal on the battery it just may solve the problem. It would give me two positive connections directly to power.It just might be that when the unit got hot it was just too much juice for that small of a wire. I'll also pull all my speakers out and check their connections while the unit is trying to play. Thanks for all your help!!!! Paul H S/V Linda Belle 95 H26
