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!!

Coby MP3 USB port loose and wriggly?

If you know anyone who can solder surface mounted parts they can probably solder it back. Sounds like usb connecter has come loose from the circuit board.

My picture and video screen is green

The The screens on these things are LCD or OLED. For the price, it is likely an LCD and the whole thing made in China.

In both LCD and OLED, a Red-Green-Blue color system is most common, and a color failure across the whole screen is most likely due to a damaged or contaminated circuit within the device that is causing an incorrect signal level to one of the colors. (It may not be too much green, it may be too little red or blue...)

The failure can be anywhere between the graphics driver on the circuit board and the pixels in the display. A bad solder joint or ribbon/flat cable connection are the most common manufacturing defects, and a drop or dunk are the most common handling damage.

If it were me, I would take it apart and look for something simple like unplugging and re-plugging the wires from the screen, and if I found nothing, I would put it away for spare parts or just use it as an mp3 player.

The next step is to try cleaning the circuit board with dionized water (distilled is OK). The battery must be disconnected before doing this. If you see any brownish residue, this is probably soldering flux and can cause electrical leakage. Some types of contamination will not be visible. If water does not work, then try rubbing alcohol followed by de-ionized water.

To clean it, the safest is just to rinse it or use a cotton swab gently only any obvious stains taking care not to push an any of the components the circuit board. If you decide to get more aggressive, then you should do a little reading up on circuit board re-work procedures.

If there is nothing obvious, I doubt that is is worth the effort and time to get spare parts for something that inexpensive. You could get another and keep that one for parts for less than $40.

Need wiring color codes, cord pulled out.

form top to bottom, for the wires on the power connection side (right) Aqua (A), Brown (S), orange (LR), yellow (LG), black (G), red (L). The letters in parenthesis indicate the letter by the connection on the circuit board.

My MP3 suddenly only plays in one ear piece (speaker side) I bought a new pair of heads phones and it is still the same. What's happened ?

Notice the plug is sectioned into two or three bits by black lines? Each section corresponds to a 'connection' within the jack--one for each of the stereo channels

If you are pushing the earphone plug deep enough into the jack to make contact with the respective sockets and are still not getting all (both) channels, most likely one of the wires connected to the jack (socket) or the corresponding circuit (board) has either shorted out or is no longer connected.
If you can open the device, look for a thin red or black wire that is no longer connected/soldered. Splice it or re-solder it.

Failing that, the jack itself may have cracked (due to excessive bending when you insert the plug).

Je ne suis pas capable d aller dans mon mp3 il ne le reconnais pas et il a une erreur allors je ne peux pas mettre ou enlever des chanson

réinstalle le firmware du mp3 et cela devrait régler le problème
tu devrais trouver le firmware sur le site du fabricant du mp3
dans la section support.
une fois téléchargé, connect ton mp3 et ouvre le ''firmware updater''
il devrait trouver le mp3 par lui meme sinon aide le à trouver le bon lecteur soit le lecteur E: ou peu importe
une fois que cela sera fait déconnect le mp3 de l'ordinateur de facon sécuritaire a l'aide de l'option retirer un périphérique
et ton mp3 devrait maintenant te permettre d'ajouter ou de suprimer des chanssons
Bonne chance

I have one that had the same problem. I solder the jack back on but noticed that the solder pad came off the circuit board. Look at the circuit board and find the component where the connection from the solder pad leads. Using a piece of wire you should be able make a new connection. even after Soldering the jack back on, check to see if the pads inside the jack are bulging out enough to connect to the headphones. The constant wear and tear from rocking the headphone jack back and forth is what causes it to "brake". Could happen when its on your pocket.
