Did I fry my player or can it be fixed

It is possible that you have connected an adapter with a higer voltage or one with a wrong Polarity. In both the cases it is possible that the front end of the player has damaged components.
In some cases there is a possibility of the ZENER which is the protection in the input circuit that could have burned and saved the cicuit as it is normally connected to protect in parallel.
SO you need to check this out , also the short can burn up a fusible resistor or fuse and so could save the circuit. Use a mulimeter to check this section of the circuit. If not there will be serious damage on the main board.

Pls check fuse of ur Cdj's

the best way to fix your issue is to replace your mp3 player batteries. you can do this by contacting the shop from where you purchased this player.    

It may be that the firewire cable has been inserted the wrong way round. Unfortunately this is a common problem as it is quite easy to do this especially when fumbling around with limited access behind the deck. Worst case scenario is that the Firewire circuit board has been fried! Firewire connection carries 30 volts, and if this connect to the wrong pins - pop goes the board. It's a £300 job to fix (I think). But first of all try pairing down any patching / connection to other equipement to a minimum to ensure that there is not something else in the chain that could be causing the problem.

Your car adapter is fried.

Try this -

1. Remove any USB devices such as ipod, printers etc etc

2. Remove the ac adapter and the battery

3. Press and hold the power button for 30 seconds.

4. Put the ac adapter back in but not the battery

5. Dont plug in any other devices and turn the computer on.

Page 205 should answer your question.

You can purchase a "AC to USB" power adapter for about $30

I have the same problem and Iriver told me the hard drive is shot.

Unfortunately they will not / can not fix it as they have no "out of warranty repair," nor do they have anyone who will do this for them.

Hold the power button for a while. Then it'll turn off.
