Coby c-858 reading no file-no mp3 signal

I know from reading the user manual that it is meant to play WMA
files but you may have to use the coby media manager to convert the files to mp3 or possibly to wma ( that the player can read )
I have similar problems with mp3 files that do not play in my car mp3 player .

Check the specification of your MP3 player to determine the type of video file format it uses. Most common video files that MP3 players use are, AVI and WMV, there may be others such as FLV, MOV and DivX. If your player cannot play a video then it is an incompatible video file format, then you need to convert that video file to a format that your MP3 player uses. After video conversion then copy the video files to your MP3 player using the USB cable from your computer.

Hello,
There's a firmware update for File Sys Error for the MP610.
Go to the support site:
http://www.cobyusa.com/?p=support

Enter MP610 in the Product Search bar: All support for this player shows up.
Select and download the Firmware Update. After the download unzip the file and read the pdf file for instructions to solve the display malfunction.

It sounds like your file system may be damaged. Following these instructions for fixing your Coby Mp-610 MP3 Player will fix its file system, and allow you to add music.

Here are instructions for a solution to your frozen Coby 610 problem. This works even though the MP3 player is having problems talking to your computer. They should communicate fine after this update.

Replacing the firmware of your Coby 610 MP3 Player will unfreeze it and help it act normally again. This will also fix the 'File System Error' that has been popping up with some Coby 610 players. You can find it at the cobyusa.com website by choosing 'Mp3 & Portable', then 'Mp3 & Mp4 Players', then your model 'MP610', from the support page. Or, here is the direct link to the file from Coby's servers.



Unpacking the zipfile from the Coby Website will give you a PDF file with instructions, and a program file to run.

Your music will be erased when you run this firmware update. The instructions suggest that even if your mp3 player won't startup properly, if you plug it into your computer you should be able to access it as a removable disk, and copy all your music to a temporary folder on your computer.

Here are the steps:

1. Plug your MP610 into your computer.
2. Copy all your music to a temporary folder.
3. Disconnect your MP610 from your computer.
4. Disconnect as many USB devices as possible from your computer (to simplify identifying the MP610 at a later step, and avoid damaging other devices by trying to load the MP610 firmware into them by mistake.)
5. Run the Firmware Update program 'MP610 T LCD Firmware Update for file sys err.exe'
6. You will see a screen with up to 24 numbered, empty boxes.
7. Connect the MP610 to your computer. It will show up in one of the boxes.
8. Once the MP3 player shows up, click on the Firmware Feature icon to start the firmware upgrade.
9. After the firmware update is complete, you will receive a checkmark in the firmware box.
10. Disconnect the MP610.
11. Close the firmware update software.
12. Turn on the 610 to confirm it starts up and the display reads 'COBY'.
13. Plug it back into your computer and copy your music back on to it.

I hope that helps.

To fix this problem I found a fix at the coby website. I downloaded this zip file. Unzipped it and did a drag and drop of the font file onto my coby when it was plugged into my usb port. Now I can read my menus again. Yippee!!

I had the same problem and solved it by: formatting the Coby MP3 player (again) in Windows Media; creating a new playlist in the window that appears at the left of the screen; synching the new playlist to the Coby; and when the player was 100% synched I left the Coby in my PC until I shut it down completely. Only when I saw that my PC was shut down, did I remove the Coby and it worked fine.
