Mp3 failing to connect to the PC

Sounds like a main board issue.

Have you checked if your USB port is active and working?

The main pc power supply is failing, this is an easy fix with any generic pc power supply.
most competent persons can do this themselves with a little caution and a photograph before you remove the old one...!
good luck !

The power source in your pc is failing - replace it ASAP or it might fry the entire pc.

Hi, Sony NWZB133F MP3 Player not recognized by the computer

This may be caused by one of the following:
1. Minimum system requirements were not met.
2. Corrupted drivers.
3. Computer restrictions.
4. Power issue.

To resolve this issue, try the following solutions:

SOLUTION 1 - For brand new player or first time connecting to this computer.

For Windows XP users: verify the following operating system requirements are met.
- Windows XP SP2 or higher
- Windows Media Player 10 or higher

Download and install the latest Windows Media Player if it's not installed.

For Windows Vista users: If the player is seen in My Computer when using MTP mode, but not showing in Windows Media Player.
- Download the hotfix from http://support.microsoft.com/kb/939211.
- Run the hotfix.

For MAC users, see Sony NWZB133F MP3 Player not recognized by a MAC OS

NOTE: If you are trying to connect to a Computer at work that is part of a network, there may be user right restrictions that are set to disable access to new hardware or stop any program installations. You may need to check with your IT administrator to see if this is causing the problem.



SOLUTION 2 - Refresh the driver

STEP 1 - Connect the Sony NWZB133F MP3 Player to the PC
The screen on your player should turn on, show 'Connected' and indicate the battery charging or full.
- If the player does not turn on try other USB ports or on another computer if one is readily available. Ensure you are connecting directly to the computer USB port and not to a USB hub.
- If there is nothing showing on the screen and the player does show up in as a storage device in an explorer window, then the screen is just not working.

If you receive the error "USB Device Not Recognized" on the computer, the player is most likely failed. Additional troubleshooting is unlikely to correct the problem.


STEP 2 - Check under Device Manager
1. Right-click My Computer, and select Manage.

2. Click Device Manager on the left pane.

NOTE: Sony NWZB133F MP3 Player can connect to your computer in MSC or MTP mode. Exceptions are Sony NWZB133F MP3 Player Connect and Sony NWZB133F MP3 Player Express which only use MTP mode. MTP mode is the recommended and default method for Sony NWZB133F MP3 Player when used with Windows OS.

The Sony NWZB133F MP3 Player will show up on Device Manager's right pane as:
1. USB Mass Storage device (if the player is set to MSC)
2. Portable Device (if the player is set to MTP mode)

If there is a yellow exclamation point (!) or question mark (?) beside the device, try to refresh the drivers.


STEP 3 - Refresh the drivers
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action then select Scan for hardware changes.

NOTE: If a device with yellow exclamation point (!) continually appears and disappears, then the player is most likely failed. Additional troubleshooting is unlikely to correct the problem.


Have a nice day....

Hello

Connect your Sansa MP3 player to more than one USB port on your computer. Ensure that your computer USB port is not corrupt or disabled by testing at least two available ports. This is especially useful when you possess no other USB-based equipment.

Inspect your USB ports' status to ensure they are enabled on your computer. Right-click "My Computer" and launch "Properties" to verify the availability of such connections. Select "Device Manager" from the Hardware tab and click the "Universal Serial Bus Controllers" from the list shown. If a red "X" is shown, the USB ports are disabled.

Ensure your computer is updated by clicking "Start" and launching "Windows Update" from the Programs menu. Alternatively, inspect your USB port connectivity through your motherboard BIOS settings. Note that BIOS access and settings varies by mother board manufacturer.

Scan your computer for new hardware changes. From the Device manager, click the "Action" menu and select "Scan for hardware changes" while your Sansa MP3 player is connected. Allow your computer to attempt to find any physical component recently added in the event it failed to previously detect it.

Connect your Sansa player to a different computer. Test the connection on a different system's USB port to verify that the Sansa device's own connection has not been damaged. Inspect the USB ports on the computer in question as well to eliminate the possibility of both systems having problematic USB ports.

Change your Sansa MP3 player's USB plug. Sometimes the head of the plug may lose contact with the appropriate circuits. Obtain a secondary USB port at your local retail store and test it on an updated computer system.

Possible reason could be frequent use would have damaged the port connectivity, If there is another usb port use them or else you can clean them to se it this works. if not try to fix a USB extender which can be procured from any PC harware shop that might sometimes give a good connection , thre after do not remove this connector but use the extender port.Check to also see if your USB drivers can be reinstalled, check though the device manager/ ports. Helpful? Good day.

Dear its ur pc usb port problem. so don't worry about ur pen drive. if u change ur usb port then it become ok to ur pc. thanks

I had the same problem... did you realize which the solution was?

sounds like bad news - if the flash (update to firmware) failed during update, the item is more than likely dead. Warranty return possible? Can you try another usb device on that same pc? just to verify the usb ports are working properly and supplying proper power to the devices.
