The Nokia 3395 is the upgraded version of the Nokia 3390. Coverage is available on AT&T networks (which used to be Cingular).
If your Nokia 3395 will not power on after pressing and holding the power button on top of the device, there is a good chance that the battery is not working. First, charge your phone (use the provided power cord plugged into the wall and phone in the larger circular opening located at the bottom of the phone) for at least one hour. Try turning on the device again. If this does not solve the problem, the battery will need to be replaced. Battery replacement guide.
If replacing your battery has no effect on the ability to turn on your phone, then you might have a bad power plug. To replace the power plug refer to power assembly replacement guide, specifically Step 11.
If replacing your battery and power assembly does not fix your problem, then you need to replace your logic board. Please refer to the logic board replacement guide.
Keypad lights up, calls may be placed, but display does not change or show anything.
If the above conditions are met, there is a good chance your screen is broken and needs to be replaced. Check for visible cracks in the screen and/or black LCD "ink" near the screen. If either of these are present you need to replace your screen using the screen replacement guide.
The phone can make calls but you cannot hear the caller.
If you cannot hear the caller but the phone displays a connected call, then your ear speaker may be broken or disconnected. First, you need to check if the speaker is connected to the logic board. To get to the speaker refer to inner components guide (specifically Step 13). If it is connected then you must replace the whole ear speaker unit.
