okay so here's the thing, i put an EU MM3 modchip into my ps1 SCPH-9002 and followed the 7 wire installation guide from eurasia (where i bought the chip from) and when it boots up all I can see is a black screen... I get literally no dsplay or audio at all... i even tried an alternative wiring method (jse07 posted a tutorial video on youtube) with the same result as the original wiring.... can anybody help me please??
I'll post a photo when I get back home. Not checked if it still works without the chip yet. Thanks guys I'll do what you said and get back to you with pictures
