Blackberry Bold 9780 No Display Light History:

Because of we i am running a cellphone repair shop, I get this phone for repair from one of my regular customer. We mostly doing latest smartphones, Because old phone don’t give enough revenue to survive in this field i rejected this because i have not spare LCD for Blackberry Bold 9780. He came back and come again after few days with a spare phone. so accepted and started fault tracing.

Blackberry Bold LCD Light Solution:

I have noticed that Blackberry have used 3 FR ( fuse Resistor ) and i found one from these was not working, That was used in series of light control circuit. I have pointed this with arrow and 1 digit. So in my case this was damaged and with multi meter this was not showing me any continuity. So i removed this and made a jumper that works like a charm.

Marked part in picture below was broken where so making jumper at this place works for me without any problem. I suggest you to check part via multimeter before removing and starting modifications. If marked part in picture below where working fine then check Resistor near sim socket.

I hope this method will work also for you. If you have any problem regarding this post please write in comments below. I will try to answer as soon as possible. Follow us on YouTube, Facebook, Google Plus for more.
