After turning off the phone, the mini screen begins to emit a soft glow and, runs down the battery overnight. This seems to be a new problem.

Check If Battery Will Charge

First, connect your tablet to the power adapter. Hopefully the tablet will recognize the charger and begin to recharge the battery. If it does not, the battery may be defective and need to be replaced.

Faulty Display

If you determined that the battery was working, it is possible that the display is broken. If no light or images are visible, but the tablet has power, then the display may need to be replaced.
Bad Logic Board

If none of the previous solutions solved your problem, check all of the connections from the display to the logic board. If the device still does not turn on, the logic board in your device most likely needs to be replaced.

Screen Doesn't Respond to Touch Nothing happens when I touch my screen.

Screen protector/tablet case interferes with the touchscreen

Try removing your screen protector or case from the device, and test the touchscreen again.
Caution: Some screen protectors may not reapply properly.

Perform a Soft Reset

A soft reset restarts your device and does not erase any of your content or data. Begin by pressing and holding the Power key until your device turns off. Wait a moment, then press and hold the Power key to turn your device back on.

Bad Touch Screen

The touch screen may be bad and need replacement. The front panel (which includes the touchscreen and digitizer) should be replaced.

Bad Logic Board

If the problem persists, the logic board may need to be replaced.

Tablet Overheats Tablet is too hot to touch!

Reset the Device

Hold down the power button until the device shuts off. Let it cool down for a few minutes, then hold the power button until the device powers on.

Bad Battery

If the device continues to heat up, the battery is most likely defective and needs replacement. Purchase a replacement battery, and replace the old with the new.

Tablet Doesn't Produce Sound No audio from headphones, speakers, or tablet itself.

Bad Headphones/Speakers

Check to make sure your playback method isn't the problem. Check all speaker connections and test headphones on another functioning device. If the problem is not resolved, your tablet may be the issue.

Software

First try a full restore on the tablet to make sure it is not an issue with the software.

Bad Audio Jack

If the problem is still not resolved, try replacing the audio jack. If that doesn't solve the problem, your logic board most likely needs replacement.

I just had a similar problem with my Samsung Comeback. It was doing the same thing, as well as freezing and being very slow to load. My solution was to remove the battery, and the memory card, reinstall the battery and start it up again. I had to cycle through on/off three or four times before it sped up to normal again.

This seems to have happened because my phone powered down overnight because it needed to be recharged. I recharged it right away, and put my memory card back in. It all seems fine now.

Soft reset: This will clean up your phone memory. All user data, applications etc stored in the phone memory will be destroyed. Type *#7370#. Enter the security code when prompted; default is 12345.

Hard reset: This is the last resort, if nothing else works. Result is the same as a soft reset. Turn off your phone, press and hold down these keys: the call (Green) button, '*', '3'. Turn on your phone without releasing them. Leave the keys only after you see the region selection screen. You might require multiple attempts because it's a bit tricky holding three keys together.

Reinstall the firmware: Download and install the latest Nokia Software Updater. Make sure your PC is running fine, and the internet connection is stable. Then, connect your phone, and run NSU. Follow on-screen instructions. Make sure that your battery is full and that you have a charger handy, in case the battery wears down.

my phone is doing the same thing. first my mogul wouldn't change views when the phone opened up, its been doing tht for days. today the screen just stopped working. when i picked it up the screen was black and i pushed the button to turn the screen on. i've taken out the battery many times, done a soft reset many times and turned the phone on many nothing is working, does anyone have any suggestions?

change the flexi cable bro

Nokia sometimes has a glitch where if the battery is too low it will not start properly again. Let it charge for some time when turned off - a couple hours, so it has enough battery power then remove the battery for 5-10 minutes, put the battery back in and try start it. What this does is re-sets the phone so it can start again. Also if there are problems during use that solution usually fixes it as well. What is happening is due to a low battery it tries to resume where it left off and cannot load itself properly to do so. Letting it go completely dead with no battery for a few minutes lets it drop it's old info and reload it's info to work again.

maybe your stator is not charging the battery,also check you voltage regulator..

Hi,

Chances are that your battery has fried. But before you buy a new one try leaving the battery out of the phone overnight. Then put it back in the phone and plug the charger in. Even if nothing seems to be happening leave it plugged in for a few hours. Sometimes, it takes a bit of time till the charging begins (I have seen this happen on rare occasions). Worth trying before you buy a bew battery.

Hi,

Did you try removing the battery from the phone overnight?

If that doesn;t work try a hard reset (assuming you can't access soft reset - code *#7370#).

Here is how you do a hard reset.

1. Switch off the phone.
2. Hold down the following three buttons: Green (call answer) button, * button, and '3' button
3. While holding these buttons, press the power button and switch on the phone
4. When the message 'Formatting' appears on the screen, release all of the buttons

Good luck!

Try running the battery down completely (0% so it turns off itself), and charging whilst the phone is completely off (I'd suggest leaving it overnight). Repeat this once or twice, then see if your battery life has improved. Also ensure that you havent left anything on that could be eating your battery up i.e. bluetooth, and contact your supplier if the problem persists, as you should be covered.
