MP3 Player

You fried it. At this point you don't really have much more to loose. Open it up and take a look.

I had an oil burner, (for hot water), primary controller that got wet. We had a sudden thunderstorm come up, the cellar door was left open and the wind blew water all over the burner, it fried. My wonderful luck, it was the Friday before Labor Day, and everything was closed until Tuesday. Anyway, I opened it up and found a burnt section on the circuit board. I bypassed the bad section with a soldered in wire, and it worked OK. I purchased a new unit anyway, just in case.

If the music means enough to you, you can put another logic board on the drive (from an exactly matched drive) and put the drive in another matched mp3 player. Id be about 99% sure ALL electronics is completely toasted. The way your mp3 player communicates with the drive is probably not the same as the mp3 player does (file allocation and such) so there is a chance the drive could be intact. Drives usually use 5 volts and sometimes 12 volts . The odds of success are pretty low.

Like the others have said... you probably smoked it beyond reasonable repair. Unfortunately most of these devices use itty bitty components that are not at all home repair friendly. If you have electronics experience, or have a mate that is, you might open it and get lucky and find you've just damaged the voltage regulator. Probably cost too much to take to a shop. But it would be possible that the maker has a repair center you might be able to send it off too.

By the way...love your area...Cotswolds are absolutely beautiful. I've been in Stroud and Glouster quite a few times.

"you might open it and get lucky"

That was my point, and in this case, he would be very, very lucky. Worth a try though.

And yes, I agree, I love the Cotswolds. We did some hiking there in '06. Maybe now that the quid is better priced against the dollar, I'll have the opportunity to return.

Hello Bondy111:

I think you really know the answer but was afraid to accept it? If you open it you will find a couple of eggs..........FRIED ONES! No offence intend but, you nutter? How on earth did you do it?

The good news is that 12V is enough overvoltage to have burned up something quickly and maybe completely. That one thing, whatever it was before, could have become a fuse in a brief flash and protected the rest of the components. That is a lot of if's and maybe's, but what the hell - open it up and see what if anything is visibly burned. Then see if the damaged components are replaceable - diodes are very good that way, as are voltage regulators, transistors and mosfets.

If you haven't already done so, you should restore the 3.7V supply and take steps to ensure that the 12V isn't reapplied.

Thanks everyone. I went out and bought a new Creative Zen Plus 2GB today, it should be enough to pass the time until I get a 16GB. I tried taking it apart, got the front off, got the screen out, but the rest of it, just wouldn't come out. Never mind, and thanks for all the advice. PS. Cotswolds are a lovely place to live

Hello bondy,

just joking, but why do you want to keep taking things apart? Looks like they designed the latest one you have with you in mind! As you could not get into it.

Ahh...let the magic smoke out of it huh? The only thing I took out of electronics was if you let the magic smoke out, it will never work again. My wife cooked by cell phone one time when we were on vacation, I had forgotten my charger and she decided to use her charger on my phone while I was in the shower. By the time I got out of the shower and to the phone, the battery was already DOA with the cause of death being rapid overload. Replaced the battery and it was fine for a while but then it started to "forget" who it was and I needed to call the cell phone company so they could download a new brain into it. A new phone was just a few weeks away.

There was no smoke.

Next time try 110Volt gives much nice effect

You turned a "Jukebox" into a "Junkbox", clever....what ever gave you the idea that supplying it with 12 volts was going to have a "good" result?????

the switch on the 12v adaptor was at the wrong end

In Holland we say "Meten is Weten" to measure is to know,

always check those multifunctional adapters beforehand

Bondy111, a circuit like MP3 usually use some fuses, you can check the fuses, they are little black component like smd resistor, and there's also a dc to dc converter there, hope if you can fix it you can use your MP3 again as long as no damage IC and software.
