The iPad is a great device, but occasionally, we all run into problems. Luckily, a problem with your iPad need not mean a trip to the nearest Apple store or a phone call to tech support. In fact, most iPad problems can be solved by following a few basic troubleshooting tips.
Trouble with an app? Close it!
Did you know that the iPad keeps apps running even after you close them? As part of the move towards multitasking, many apps can leave a small part of themselves running in the background in order to continue providing basic services like music or just to allow the app to be booted quicker the next time you open it.
Unfortunately, this can actually lead to some problems with the app. If your problem centers around a single app, the first step you should take in solving your iPad's problem is to close the app in question.
You can close an app by pressing the home button twice in a row. This will bring up a list of the most recently opened apps at the bottom of the screen. If you press your finger against one of these apps and hold it down, the icons will begin to shake and a red circle with a minus sign in it will appear in the upper left-hand corner of the icon. Pressing this button will close the app, clearing it from memory.
When in doubt, reboot
The oldest troubleshooting tip in the book is to simply reboot the device. This works with desktop PCs, laptops, smartphones, tablets and almost any device that runs on a computer chip.
If you are having a problem with an app and closing it doesn't fix the problem, or if you are having any other type of problem, the best step to take is to reboot the iPad. This will clear out the available memory used by applications and help give the iPad a fresh start.

iPad won't turn on
No matter what you do, you can't get your iPad to turn on.
Press and Hold the Sleep/Wake button
If your iPad's problem isn't so easily solved, read on.
If your iPad won't turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your iPad into your computer or AC adapter and see if anything happens. Ideally your iPad will recognize it has been connected to a power source and charge its battery. If it will no longer charge, the battery must be swapped with a replacement battery.
It is possible that it appears nothing is happening because the display is bad. If the battery is working properly but nothing is visible, it is possible the display is bad and must be replaced.
Bad logic board
Ultimately, if the display and battery are not the culprit, check all the connections from the display to the logic board. If they are connected properly and there is still no life, the logic board most likely needs to be replaced.
Touchscreen input not responsive
Your iPad is not recognizing the touch input on the front panel
Bad touch screen
It is possible that the touch screen is bad. If so, you must replace the front panel (which includes the touch screen and digitizer).
Bad logic board
If replacing the front panel does not restore touch input, the logic board must be replaced.
No audio or distorted audio
Your iPad turns on and appears to work, but when you plug in headphones or speakers, the audio doesn't play properly.
It's unlikely your headphones or speakers are bad, but it's worthwhile to eliminate these as the source of your problem at the beginning. Try your iPad with another set of headphones or speakers just to make sure that the problem is with your iPad.
Bad audio jack
The most likely cause of audio output problems on the iPad is a bad audio-out jack. First try a full restore on the iPad to make sure it is not a software issure. If that fails to work, try replacing the audio jack. If that doesn't solve the problem, your logic board most likely needs replacement.
Your iPad displays the text "Use iTunes to restore" on startup
It isn't often that Apple gives specific directions about how to fix your problem! Restoring the iPad will erase everything on it, so make sure everything on the iPad is stored elsewhere prior to restoring. To restore, connect your iPad to a computer with the latest version of iTunes installed. When your iPad appears under the devices menu, click the restore option under the summary tab. If you haven't backed up your data already, choose the back up option from the pop up window. Click the restore button to restore your Touch to factory spec.
Bad logic board
If attempting to restore the iPad and diagnosing does not fix the problem, the issue is probably the logic board
