I have a DMS 4 EZI Pro installed in my slimline v15 PS2. Everything is in and when I turn it on, I get a black screen. Now, I have read the install manual and it says to make sure that the ground loop is screwed in tightly, and if that does not help, try soldering a new wire from the GND part of the chip to another (and closest) GRD point on the motherboard. Only problem is this: where is the nearest GND point? Any help would be greatly appreciated. Thanks!
