Broken audio on mp3 player with vid screen - can anything be done with the unit? Answered

Hi!

A while ago, my mp3 player broke:  the audio doesn't work, yet the video part works.  I hate to throw the unit out so I was wondering if anyone has had a similar situation, and what they might have done to make the unit useful again.

I could use it for storage (it's 2 gig) but it seems like a waste since it would have a screen that wasn't being put to good use.  Then again, without audio, any video would be as good as it cold be.

Any ideas would be appreciated.  (I'm a novice at electronics - I'm hoping that an idea for its use will b e figured out - that doesn't require me removing the screen (since i am not that advanced in electronics)

Thanks and have a great day! :)

BTW- if it is any help, it is a generic mp3 player that looks like a small ipod.

Are you sure it's the MP3 payer that's broken? Try it with another pair of headphones before you call it dead.

It isn't the headphones (already tried a different pair. Thanks though :) ). One piece (looks like a mini resistor) fell off a while ago. I still have the piece, however, even with me trying to reattach it, it will not work. Last night I was able to find out the pins for the audio - and i tested it (via a small wire): it seems as if the mini resistor that fell off may be part of an amplification circuit -- so, by rights, if i can figure out a way to attach wires to the audio left and audio ( http://wiki.s1mp3.org/ATJ2111 ) and if I can figure out the 3rd wire required, then maybe i can create an alternative amplifier circuit on another board and then patch that through speakers/headphones. (It doesn't matter if it fits back into the original case - i just want to be able to do something with it).

With the new knowledge, if I could figure out how to solder those small (to the point i need a magnifier) pins to attach wires to them (and figure out the 3rd wire for the audio) - then figure out a new amp circuit -- I should be able to use the mp3 player again. Also, it seems the battery for the unit doesn't hold a charge anymore - so doing a modification for that (once i get everything else working) would be something I'll try later on. (Who knows... maybe with a new amp, I might be able to get a higher voltage rechargable battery - that would power the mp3 player as well as a new amp circuit.)
