Hi I had the same problem and I finally figured it out.
First you will have to try to connect to the computer by pluggin it in and reseting once the computer recognizes it you should be able to look at the files.
If you are able to get the device to this point;
1. create a folder on you computer it could be in you desktop or document and name it something you would remember to go to. I named mine SONY.
2. copy all the folders from your WALKMAN to this folder;
3. delete all files from your WALKMAN there are some files it will not allow you to and just hit SKIP.
4. download the Firmware update (1.02) from the SONY Suport website: http://esupport.sony.com/US/perl/swu-list.pl?mdl=NWZE436F and select your computers operating system and download the file.
5. Once you download it run it and it should re-install all the necesary files back to you device.
6. Re-start the WALKMAN and it sould work just fine now you can go back and add your music files and photos, etc...

Good luck this worked perfectly for mine.

It may be a loose ribbon cable going from battery compartment to main circuit board. THey have tendency to work loose.

Check the connector of the USB Ports and Sony. Also it's internal battery require replacement.

did anyone ever get back to you on this? I'm having the same problems.

Hey! We've had a similar dilemma, and we solved it by connecting walkman to computer, then going into 'device manager' uninstalling the walkman, then remove it from usb port and re-connect it.

The computer will then 'recognize new hardware' and automatically re-install the walkman. Good as new!

Hope this helps!

have you tried to format it

Your only solution, if you have tried all of those methods, is to replace the USB cable or find out from Sony if you still have a warranty on that product. The help page and Sony's phone number can be found here:

the battery could be dead
