Ipod nano 4g accelerometer problem

Does it have a green line in middle of screen ??

Apple has some suggestions to try before taking it in to an Apple store. Most iPod Nanos are covered by a one year warranty, and you may have purchased a longer warranty. For questions about your warranty and coverage, call Apple customer service. If your iPod is still covered and you live near an Apple store, it may be faster to take it in.

Charge the iPod Nano for several hours to make sure the problem isn't a low battery. Force reset the iPod Nano by holding down the Sleep button and the volume down button at the same time for 8-10 seconds or until the Apple logo appears. Restore your iPod Nano by plugging it into iTunes and clicking on the iPod, then "Restore." This will wipe all information on your iPod Nano and install the latest version of its operating system. Re-sync your data to the iPod Nano after a restore.

is it an ipod nano ?

Remove the two screws on the panel on top of the Nano and remove the top panel.

Use a case opener tool to pop the plastic screen cover off the unit.

Slide the screen up to expose the orange ribbon cable on the bottom of the screen that connects to the motherboard.

Unplug the orange ribbon cable from its port and slide the screen out of the Nano.

Fit a new screen in the Nano and plug the ribbon cable into the port.

Replace the screen cover and top panel of the Nano.

hope this helps

i had this problem recently, to solve it i had to manually reset the device. to do this, set your ipod on the table screen up, then press and hold the menu and center button at the same time for about 10 seconds. if it rests, you will see a black screen with an apple logo. it'll take a second but then your screen should pop back up and hurray!

hope this helps!

try holding the power button and the home button together for like 10 seconds

Get one of these to sole your problem. ipod change their charging circuit I found one at Walmart in the ipod accessories section. Its called the Passport home dock adapter.

- this accessory supports charging for the iPhone 3G, iPod touch (Gen 2) and iPod nano (Gen4) with most iPod docking stations
- Snaps into any iPod universal dock and accepts universal dock adapters

if by the on/off thing do you mean the hold switch?
If you do, make sure it's to the left. If it is to the right it disables the keys. Other than that, to turn on press any button. To turn off hold play for 3-5 seconds.

You hold down the play/pause button until the Apple logo appears.
