Ok, this is my third magic 3 install on a v7.
First time I had a bridge bios, sound was funky and had boot problems.
Second time, dead on... worked first time.
This time. I got no joy. Black screen. No video, no sound, no electrons. Nothing. I disconnect the +5, still nothing. Checked and double checked for bridged pins on the BIOS. Can't find any.
Is this a case of the black screen of death?
Any ideals for a remedy?
Thanks!
All your wires should be as thick as possible - the thicker the better! From memory though the only connection points that allow safe connection of thick wires without shorting on other pads or pins are:
Power
Ground
SCEX
Reset
R or Z
All other connections need wire that is around AWG30.
As to the wire length - as always - with signal connections keep all wires as short as possible - try not to lay the wires to close to crystals or any other oscilating frequency generating device on the main board as these can induce noise into your wires.
Also avoid bending the wires sharply - i.e. in right angles as corners on signal wires are also to be avoided.
Also ensure all ribbon cables are reconnected when assembled again - especially the one just off center of the board that connects to the laser unit - this can be pulled loose easily when re-assembling.
Lastly double check all you wiring to ensure that connection points are correct that the wires are not shorting and that they are firmly soldered i.e. a gentle tug should not pull them loose. A multimeter to check continuity would also be useful.
You may have solder splashes or loose balls of solder as that would stop you station with the chip removed as well - but check for these as well.
oh and good luck - it always sucks when things don't work first go.
Never had one fail completely like that though - I would avoid powering it up again until you locate the fault - may end up blowing components...
Does the fan still spin - i.e. have you blown the power supply??
Thanks for the info...
Yea, I had 22AWG for the power and ground. 30AWG for the
rest. Kept all the wires as short as possible. Ran them away from any components.... I thought this was my best looking install.
However, I gave in and backed out the install. Totally removed the chip and at least now the PS2 is back to normal.
I'm admitting defeat and returning the PS2 to it's owner. I'm by no way a pro at this stuff and I guess my luck has ran out. No more mod install favors for me. I am done.
