The manual pretty clearly states not to replace the battery - the manufacturer usually has a way to fix any issue you are having with the player. Now that you have damaged the player yourself, your warranty is voided. sorry about your luck

The tweeter stopped working on my Ion Block Rocker, any suggestions? Tore apart, all wires are still connected.

Take the tweeter out, and tap wires to a AA battery to the connectors. If no clicking sound from tweeter, it's fried, and you need to replace it.

Just opened my ion block rocker box and got the unit out and tried to charge it. It won't charge and the charge light only lights for about 20 seconds and turns off. It won;t operate unless plugged in and...

Just repaired my Job Rocker !! Just like most everyone here mine worked fine but would not charge. This may be how to fix yours.

Follow the red wire up from the battery to the circuit board and carefully try to disconnect it from the circuit board. Odds are the male spade connector will come off the circuit board. That's because it never got hot enough for the solder to actually stick to it when it was assembled at the factory. With time, the expansion and contraction from the heating and cooling of the circuit board causes this poor connection and prevents electricity from getting to the battery.

Remove the male connector from the female part using plies (this was difficult and required wiggling the connectors back and forth while pulling hard - and I'm not sure if it is absolutely necessary ).Clean the two prongs on the male connector with some fine sandpaper or an emery board and put some solder flux on them. (If you are unsure how to solder watch a few videos on Youtube or get help from someone who can) Heat the prongs up with a soldering gun or iron and coat them with some solder. Carefully remove the circuit board (by removing 4 screws) from the plastic panel to which it is attached.Then insert the male connector back on the circuit board while heating up the solder on the back side causing the connector to properly solder to the board.

Carefully plug your female spade connector back on the male spade connector you just soldered on the board. After making sure the circuit boards are not touching each other, plug your unit into the power and see if the charging light and the other 3 LEDs light up. If they do, unplug from your power, reassemble, plug back in and enjoy. If the don't, check where the black wire from the battery attaches to the circuit board and repeat the same procedure. Good Luck !

Please post your results so we can all know if this is a common problem and a good fix! Thanks again!!

My smpk4083 wont charge

It can be 1 of 4 things. 1: the way your charging it. 2: the cable. 3: the battery. 4: the conection on your device.
1: Try charging it different ways. (Different wall outlet, laptop, computer, etc.) (Note: some laptops and/or computers might not have a strong enough charge to recharge certain devices. You'd have to adjust the power setting in the control panel or the manufacturers setings.)
2: Try using a different cable. (If you don't have one try wigleing both ends to see if you get a charge.)
3. Try another battery. (Most people overcharge batteries thus shortening the recharging capabilities.)
4. Check to see if any of the pins are messed up or missing on where you plug the wire into your device. (If any are missing you can open it up and replace the part.) Sometimes people end up pushing them in by accident when they conect there charger, so the wire doesn't make a good conection after a while (another case where wiggleing the wire could work).

When i conect it on the pc its appears only transfer mode it shows also the batery is empty and usb conected ready it doesnt turn on

Try a new USB cord and make sure your driver is updated. Try a different USB port on your PC as well. They can go bad. You may try to remove the battery for a minute and then reinstall the battery and see if that resets it and has any effect.

Dead battery?

Battery is bad. If you use a dock most of the time, it is overcharging or never gets the chance to relearn its capacity. If it just shows low battery but will still work, just run it with a low battery until it shuts off. Then recharge it completely. Do this three times. If no improvement, you need to replace the battery.

How do I replace a battery in this device?

Replace the Battery
  1. Remove five screws: two on the side, two on the bottom and one on the back behind the lanyard hook. When that screw is removed, remove the lanyard hook insert.
  2. Slide the metal backing down as shown in the photo. Then pull it straight up.
  3. Unhook the ribbon connection attached to the metal backing by lifting up on the brown flap where the ribbon is connected. The ribbon will then slide out.
  4. Pull the hard drive back as shown in the photo.
  5. Remove two screws near the bottom of the player. One is on the bottom and one is on the right side near the battery switch.
  6. The battery is now exposed. You can disconnect it by gently pulling on the red and black cables.

How to change battery for Samsung Napster YH-920 MP3

DON'T DO IT! I was SO EXCITED to find this post 2 days after it went up. It addressed exactly the problem I'd been having with my YH-920 (getting maybe 30-40 minutes off a charge). I ordered from the suggested supplier (not cheap at today's exchange rate) and eagerly tore into the project Thanksgiving night. Disassembling the player is as easy as advertised, but the replacement battery simply DOES NOT FIT the machine. advertises it as a replacement for the YH-920, and the package is stickered with the same information, but it's between 1/16th and 1/8th inch too long for the battery bay. Trying to make it work destroyed my MP3 player ("device can't initialize HDD," a message I still get after reinstalling the original battery). Now I'm trying to get a refund. Wish me luck.
