Battery and Black screen Blue ring: Remove the back and check and see if the battery isn't fully connected
push softly but firmly on the Rubber rectangle above the battery (This is the Chip-set For the screen, and memory "Black screen Blue ring" ) and put the back on.

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.

Only 2 suggestions here: 1) Make sure your HOLD switch is not enabled. 2) Try to update the firmware If neither of these work, time to send the unit back to Sandisk

The motherboard is messed up. There is some corrosion on it. you are going to have to get the motherboard replaced. our company can fix it, but you will have to tell your boyfriend. Thanks, Connie

Hi. Seems like your player may be encountering some corruption. Try this and see if it would help: Switch your Sansa E250 to its Recovery Mode: 1. Make sure the player is powered off 2. Enable the "Hold" switch (located on the top of the player). You would know it's enabled when you see the "orange-colored" surface 3. Press the "Record" button. Make sure you keep it pressed while pressing on the "Menu" button. 4. keep your fingers pressed on these 2 buttons until the E250 LCD screen displays "Welcome to Recovery Mode" 5. Connect your E250 to your computer. (Just a reminder: The minimum Operating System requirements for a Sansa E200 player is Windows XP and above) 6. Double-click on "My Computer" and you would see your Sansa E250 appear as a "16 MB" drive. Note: If you do not see that "16 MB" drive/partition, please repeat steps 1-6. Next, Apply the firmware for the E250 (your player should be connected to your PC at this time): Step 1: Use this link to download the firmware for your Sansa E250 (for better results, please save this file on your "Desktop": http://www.sandisk.com/Assets/File/Downl... Step 2: Double left-click on the downloaded file, and follow the on-screen prompts. The file will automatically re-flash your player and format it as well, thereby clearing all possible file/system corruptions that may have occurred. Step 3: When the process is complete, unplug your E250 from your computer, and please make sure you disable the "Hold" switch Step 4: Power up your E250 and 90-99% of the time, it would boot up successfully. Let me know if this helped :)
