Re: Sony Ericsson K750i

Your Keypad IC is damaged, also your keypad either needs cleaning as suggested earlier or replaced which is a very common problem with K750i. You need to take it to a service center to fix it

My sony erricson k750i phone's joystick is not responding

you have to clean the joystick by using contact cleaner. open the cover of joy stick, there is a switch inside it having a metallic cover. use contact cleaner and let it for few minutes.
DONT FORGET TO REMOVE LCD FIRST. it can be damage with contact cleaner. i had a bad experience of it.
btw it happens with sony ericsson phone joystick problem.if joystick problem still persist u have to show it to sony ericsson repair centre or your warranty center of mobile.and u can also use the keys your keypad keys for up down left right.

My sony ericsson k750i joystick is broken.

Your joystick might have accumulated a lot of dust inside it. Try to clean it with alcohol or blow it off with some high high pressure air.
