c905 will not display

[Teddyb]

Hello , 

I have just replaced the screen of the c905.

The phone will power on and the display will light up. also sound of powering on and off will play but display is blank black. I can see light on the display but nothing comes up.

What else could be the problem? thank you

Perhaps the LCD wasn't properly connected, it could be that the motherboard its damaged, if so then it will cost you almost as much as a new phone. Double check the ribbons.

Don't forget to give Kudos

What exactly was the problem before you replaced the LCD? Have you tried running the update service on it via PC?

Also, have at look at this disassembly guide, in case there was an error with the replacement: http://www.formymobile.co.uk/c905disassembly.php#.UjXQmipwZMs
