The phone will not power on.

Check that your battery is charged and securely in place. Also check that it is not dead. Old batteries may suddenly die without warning. Check the contacts to ensure there is no residue.

Disassemble the phone to make sure that the phone's logic board is not fried.

Make sure that the actual power button is still working and connected.

You cannot make or receive calls.

This is probably due to a faulty logic board. Disassemble the phone to check for any obvious problems.

"The phone shuts off without being prompted"

There is likely a problem with the battery. This is commonly caused by residue on the contacts. Use a pencil eraser and clear the contacts of any dirt. Clean away all eraser residue.

Check the manufacturer's website for replacement screens.

Disassemble the phone to see if the keypad is still intact. If so, check the manufacturers website for replacement keypads.

If the keyboard is not broken, there is likely a problem with the logic board. Look for any visible faults.

"Or they cannot hear you"

This can be due to a faulty speaker. Check to see if any other noises can come out of the speaker.

If someone cannot hear you it may be due to a faulty microphone. Check the other phone functions to see if it can record at all.

Your logic board may be faulty. Disassemble the phone to look for any visible problems.
