I phone4 wont start

[bardipur.sagar]

i Phone 4 screen remains blank and only the apple logo appears on and off when connected to mains or PC. Only on mains occasionaly proceeds to display IOS 6 logo and a slide sign to start recovery which proceeds to an instruction to connect to iTunes. Hwever, as soon as disconnected from mains (in order to connect to the PC) screen goes totally blank again. On connecting to PC the Apple LOGO starts appearing intermittently but does not proceed to display IOS 6 LOGO. I have recharged overnight and followed resetting instructions as per the iPhone support page. Any suggestions (short of taking it to a service centre) ?

I think the Iphone it's on DFU Mode.

Maybee.

Your boot process is being interrupted. Might be a kernel problem. My recommendation is to do a full DFU restore to put in a fresh copy of iOS to make sure everything runs smoothly. There really is no alternative to solving this problem.
