Hi there.
Could someone please advise me on how to make the connection to the test point on the 8330 as the pad is so small and right next to both the chip and other pads that I can just about see it let alone solder to it. Add to this I need to connect the keypad board on top so as to be able to press the power on button momentarily. Have I missed something somewhere or do I need to perform a massive feat in soldering. Any help would really be appreciated.
Regards bouncerdove

2 wires ended by small grips (crocodiles)
1 wire ended by a small grip and a needle.
1 Dismount the phone to extract the pcb
2 connect the battery to phone with 2 first wires.
3 connect the last grip to the ground and use the needle as probe.
with vygis, no matter to worry about time (chrono) . the procedure is sequential. connect and disconnect the probe only when requested.
the power on button is wired to pins 1 and 2 of the central connector.
best regards,
Aishur

AishurThanks Aishur, could you or anyone lese please tell me what you are referring to as the central connector?
Am I right in thinking it's the long rectangular connector in the middle of the PCB, which the "chip" on the keypad PCB slots into?
If so, are pins 1 & 2 on the top left? (It says 1 on the top left corner, and 60 on the bottom right corner?)
And, if I am right in assuming all this, how could i get the phone to pwoer up using pin 1 and 2? Simply short them? Is that it?
I took an extremely poor photo of the PCB, to avoid any confusion on my part. I've marked out the central connector and pins 1 & 2. The PCB is the normal way up, ie the battery terminals are on the bottom as is the USIM slot etc. tSorry to keep asking questions but I need to be sure, to power up the phone I just to need to touch both pin 1 and 2 with wire?
Here's the picture of central connector and pins 1 & 2:
