Hi, I recently modded my pstwo V15 SCPH77003 with a matrix infinity green dot chip and now when i turn on the ps2 all it does is stays on a black screen. (my monitor doesnt receive any signal). when i turn it on, it powers up normally then after a few seconds powers down into kind of a low power state which it stays there forever and does nothing. the lase also makes a noise twice as if its trying to read but then does nothing. Please can someone help. Thanks.
