Hey people.

Just did a search, but couldnt exactly find the answer I wanted.

The question is simple, what is a PCB and what does it do?

Cheers

PCB stands for \"Printed Circuit Board\" and is the main circuit board that holds all the components together in any electronic device.

Ok thanks mate. Does the PCB have anything to do with the software/firmware of the phone?

Reason I ask is because I have a k750 with software problems preventing pretty much all the buttons and two directions on the joystick from working, and am looking at buying a k750i on an online auction site that has a cracked LCD and possible broken PCV.

Would I be fine swapping my LCD and PCV over from my phone to this one that i'm looking at buying?

Well it does because the firmware/softeware is stored on the CPU (Central Processing Unit) Chip.

You could easily get the problem resolved for you by professionals if you took it into your nearest service center.

There are no SE Service Centers in New Zealand...

I know someone who could re-flash it for me for $65, but I very much doubt it would work due to the fact that the phone, when connected to the computer, will ONLY do memory card+phone memory stuff, and doesnt let you connect to it using SEUS or anything...
There is a $25 fee if the re-flash doesnt work, and being a poor student, I dont want to risk it....

If that phones PCB is broken you wont be able to use it at all, not even power it up or flash it...

@axxxr doesnt matter but, firmware isnt stored on the CPU

Oh ok, it powers up fine but isnt really functional cos of the LCD.
So am I right in assuming the PCB is perfectly fine?

Also just want to double check, the LCD's are swappable right? As in, the actual LCD display part, not the outer protective screen (from what I hear, its kinda layered?).... if that makes any sense?

Cheers for the help guys
