Question about Sony Ericsson K750i Cellular Phone

1 Answer

Problem with buttons &navigations.

Last night i put the phone on charge, this morning i take it off charge and put it into my pocket (sony ericcsson k750i). Come to use it this afternoon and the following buttons dont work: 1,2,3,6,9,# and the left Navi key thingy, the stick doesnt work when pressed right or down, and the power button will not turn the phone off but will turn it on. I suspect this may be a firmware problem as when i move the joystick to the positions that dont work, the backlight comes on, and the power button will let me turn it on but not off.I restart the phone several times but still not working.

Double check that none of the buttons are stuck down. Try removing and replacing the battery.

Charged my phone last night and will not turn on this morning

Thats what my phone does when the battery is dead. perhaps it did not charge last night. see if the phone will turn on while connected to the charger. if so, the battery is dead or defective.
