PStwo install problem: blank screen
I've just finished moving my Matrix Infinity from my original PS2 to a new PAL PS Two.
I identified my PSTwo as PAL v14 from it's SCPH-75004 and board reference GH-040-52.
The closest installation diagram on the Matrix site is V14-GH040-51.JPG, which seems to match the board layout on my PSTwo.
Now, when I turn the PStwo on, all I get is a black screen. No disks boot up.
Is this likely to be due to poor soldering on my part, or could it be something to do with the firmware on the chip/memory card?
I usually fix the wires in place with my hotglue gun - it's an efficient way of fixing the ends in place. My gluegun broke midway through the install, so I had to affix everything with insulation tape - so it's possible something came loose.
Any help would be appreciated.
