This just happen all of the sudden.....the phone was working good and just as I walked to my room from the kitchen I tried to make a call, so I press the on button, but nothing happens, so I figured, maybe I need to reset it.......... so I took the battery off, waited about a minute and then put it back on....Nothing!!!!......the only way to access the screen is by plugging or unplugging the battery charger !!!.....Does anyone else have similar problems ???
It seems like your power button went out. You may want to go to your local service and repair store and see if they can repair and if you have TEP, we will be able to repair or replace at no charge. If you dont have TEP, there may be a charge to repair. ($35)
Sprint's new policy is unless you pay for TEP, Warranty service is charged $35, Or send it off to the manufacture.
You can read up on the policy change discussion here;
