Blackberry Hardware Repair Help - GSM-Forum

winryan · 08-07-2009, 06:34

Hello,

I'm looking to pay for some blackberry hardware level diagnostic and repair support; A professional technician sufficient in blackberry repair knowledge (especially on the blackberry curve 8300 series) at the circuit level to help me fix particular problems I have with individual units. I'd like to basically pay for the knowledge you have on specific blackberry fixes and help on identifying the different circuits and their components on the board and also identifying how they are inter-related. Also things like components that have a tendency to go out and are the first to replace to try to bring a dead board back, or a failing function of the phone back.

Here are some examples of the questions I'd bring to you (some current issues I have):

1. Problems which camera in which re-flowing a replacement camera and bracket will not fix.

2. Problems in which the phone will not connect to the wireless network and will go to the "no service" mode after searching for network (mid plate with antennas already replaced). I'm assuming this could be just a bad radio chip but I just want knowledge from someone with experience on how to proceed with problems of this sort.

3. Problems in which a group of keys will not work (for example I have a blackberry 8300 in which the following keys do not work: q,a,s,alt,left shift and space. I figure these keys could all be powered by a single component that has gone bad or maybe the middle layer of the pcb has gone bad and this is irreparable?
