Does anyone knew how to fixed no wifi, no ringtone, keypad malfunction and trackball malfunction of bb 8530 in hardware solution. Im quite not familiar regarding its components...or simple where can i have a copy of its schematic diagram. Anyone can help me out...troubleshooter minds help me.

If you could first detail the malfunctions, it would help greatly.
Can't help much without specifics.

Are you asking about an 8530 or 8350 as in your profile? Makes a big difference.

Did the device get wet? Having all of these malfunctions together sounds like water damage. If so the device is most likely useless.

yeah asking about 8530 but i do have also 8350 even 8830. Please advised for im not familiar regarding components of blackberry, i need a schematic diagram coz based on my analysis its board problem im facing on.

meh, if you've already decided what the problem is, you don't need our help.

Maybe you can write RIM for the electronics schematic.

And, good luck with that.

Alright...thx for the help i really appriciated!

Suggestions,info, and tips regarding schematic diagram of 8350,8530 and 8830 are highly appreciated.

We do not have any. We are in no way connected with RIM. You need to go there for that information.

How are you so sure that it is a hardware problem?

Because im a technician just exploring how to fix BBs...Can your help me out finding analysis how to trouble BBs. Im not familiar regarding its components. Can you help me enumerate its components.

No. You need to contact RIM.
