C905 keypad, display back light solution - GSM-Forum

Hi guys,

Got this C905 for Speaker problem. So opened up tried to trace problem thinking it would be speaker or flex problem so went ahead and changed it. Ear speaker started working but only for a few seconds as when the slide was moved up and down it stopped working again. I re-opened the phone. But then I had any other problem key pad stopped working and the back light of the display was not coming On anymore.

Now I had a phone with back light, keypad and ear speaker problem so tried changing the 2 flexes then the display with a new one but the problem persisted.

Can can anyone advice how to solve this problem.

thanks in advance

I have a similar problem. Problem came with the speaker probelm. After i tried to change the flet i lost displey light. Keypad is working fine and i have lights on both keyboards. Only display remains problematic.
I changed coild and diode but the problem is still here.
Can anyone help me with this issue.

Thanks
