[blademaster]

i guess i skrewed up bad.
i have a ###ne.
i bought a stealth 6 wire mod-chip.
i tried to install it myself.
i was doing great until the purple wire, and then i got some sodder on the chip above where the purple wire goes.
i put the playstation back together, and the CD wouldn't spin, but it would go to the "CD or Mem Card" screen.
i tried to fix my problem, and now it won't even go to the "CD or Mem Card" screen.
PLEASE HELP!!!
