Re: My mp3 player wont turn on

I have an identical problem with my mp3 player which looks similar but isn't the same model. There's something up with the play button, some moisture or grit or dust has got underneath the contact for the play button so that the mp3 player thinks you are constantly pressing the on/play button.

Put it in a warm dry place. I have had this problem twice & this has fixed the problem on both occassions. If there's more than moisture trapped inside, that can be harder to shift. But there are no moving parts in this player so don't be afraid to give it a good shake to try & get things moving.

Does not charge or play,read on computor

In order for the Coby to charge while connected to the computer or other charger, the Coby must be OFF before being connected to the computer. Check the following questions....

Can you see it in "My Computer"? It will show under "Removable Drive/Storage"

Double click the removable drive to open the folders. Can you see your music, photo and photo folders?

Can you see the player in Coby Manager - under the "DEVICE" tab?

When disconnected from the computer, how long can you listen to the Coby player before it goes off?

If not present in My Computer or in Coby Manager, then it is not plugged in correctly.
a. Disconnect the player from the computer.
b. Wait for it to cycle through "Please Wait" and "Updating Library" screens.
c. Make sure the player is TURNED OFF
d. With player TURNED OFF, reconnect wire to the player then to the computer.
e. You will see a USB connector icon on the player screen and the player charging in the battery area - upper right hand corner.

It will appear to be charging all the while it is connected to the computer. After it has been plugged into the computer for an hour, it should be well charged unless the battery is completely run down. In that case, you need to do an initial 8 hour charge with the player OFF.

f. Use the Coby Manager to disconnect the player (Found HERE CobyMedia Manager fix for MP822 (Windows XP/2000/Vista)

1. Go to the DEVICE TAB
2. CLICK on EJECT Button in lower right hand corner.
3. It will have a pop-up screen to ask "Do you want to eject?" Click YES.
4. The second pop-up screen will tell you "The device can now be safely removed from the system."
5. The Coby will now show "Please Wait..."
6. It will take the Coby about 10 minutes on the "Please Wait" screen and then on the "UPDATE the Library" screen - Be PATIENT

You should now have enough battery power to use it. To check the battery level,

1. Turn on the player
2. The battery icon is in the upper right hand corner of the screen - it is ALWAYS RED until it starts to go down... I've not had mine down very far, but believe the red line gets shorter as the battery is wearing down.

Let it run on music until it turns itself off. Recharge as above.

Hope this helps.

Just leave it until the battery runs out and it turns off by itself. Then plug it in and charge it. Once it's charged, turn it off. Then wait at least an hour before turning it back on.

Coby mp4 player mp-c79095

I didn't have a problem accessing the flash memory of my Coby mp4 until I upgraded to Media Player 11. Now it recognizes the coby for what it is, but I can't explore the flash memory like I used to. It used to recognize it as another drive, now it shows up as a portable media device. Do I have to go back to MP10 to get it back or is there another way?

Coby MP-C7085 Wont work

These players are plagued with problems! I have the 2gb version which does the same thing. I gave up on trying to use its internal battery and bought a usb charging cord for use in my car. I just unplug the cord from the cig lighter socket when I'm done using it. If it doesn't shut off,which is 99.9 percent of the time, then it just runs its battery down until it finally shuts off. It's a shame this player doesn't work as good as it looks...

It won't turn on

I have the same player with the same problem. I partially fixed my player by re-soldering the positive battery terminal. Turns out there was a cold solder joint there. I suspect that there is at least one more cold joint so I'm going to take another look at it to see if I can "fix" it once and for all.
