It is fully charged, but not recognized by the computer. I have tried holding down the power button for 20 seconds and plugging it into computer, I have tried holding the power button down for more than a minute, I have tried pressing the home button. There is no response from the home button or any of the other controls.
If this is a iPhone hold the power button and the home button at the same time until the apple logo appears, then release both buttons. This is a soft reset and won't affect anything on the phone.

These are the most common methods for recovering Sandisk's Sansa Mp3 Players. I have been almost universally successful in recovering Sansa players using one or a combination of these methods. These methods do not work if you are having synchronization or music format issues - they are for recovering a player that will not power up, freezes, flashes, is not recognized by the computer, and a host of other issues.
Reset the Sansa Player first. On most models, restart is done by holding the power button in for 15 seconds or longer. Check your specific manual to be sure. The manuals are available from the Sansa website if they have been misplaced.
Download the Sansa Recovery Tool from the Sansa website.
Format - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
Firmware Upgrade- Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/DriverDownload/driverList.asp
If these fail, then:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
If you get the problem where MTP Device keeps popping up continuously, uninstall the “MTP Device” by going to Start à Control Panel àSystem à Hardware à Device Manager (you computer may vary slightly, depending on Windows Version).
You may have to restart your computer after each of these methods to get them to work properly. Disconnect your Sansa player BEFORE shutting down your computer.

Im afraid that is a motherboard failure. A few months ago I had one in for repair with the same symptoms. Tried reflowing the graphic chip, nothing Tried reflowing the FSB controller chip, nothing. Tested power module for bad capacitors, nothing.
You could do the same steps I did, maybe you get lucky.
If this post was helpful and informative please give it a Thumb Up. Thank you.

Click on the 'Home' button and on the "Lock" button for few minutes.
If not, charge the device, maybe it's battery is dead, and then press on boat buttons at the same time for few min, that should help you.
Hope that I helped you.
SOURCE: How can I get my Samsung Galaxy Tablet to turn on. The battery is fully charged.
There is usually a method such as holding the on button for a longer period of time. If it is easy to do the other thing that I've found with all sorts of "smart" devices which turn "not-so-smart" is to remove the battery for a minute or so, then put it back in. Many times the unit will turn on as soon as the battery is reinstalled and work correctly again after that. Last ditch effort, unless someone knows about the Galaxy, is a hard reset, there may be a reset button somewhere on the unit, I don't think the Galaxy has a reset button. If the unit still does not turn on it may need servicing.
1. Try the on button for 15 - 20 seconds if you know it is charged
2. Try charging for an hour or two then the 15-20 second hold on button, #1 above.
3. Removed battery (I'd measure the battery voltage while I have it out) wait ~1 - 2 minutes & reinstall the battery. If it doesn't turn on by itself try #1.
4. Nothing works start a service ticket with Samsung, URL:

You might try searching there as well for an answer to see if there's anything I missed.
