hello. i have a bulky ps2 model...dont know the model number though. i tried to disassemble the ps2 numerous times but this is the first time i encountered this problem. here it goes:

first i tried to re-allign the lens, after successfully re-alligning it, i tried to put back the ps2 together, but the LED switches (blue-eject/open/close disc tray, and green/red-on/off/reset) so, i disassembled the unit again and as i try to fix the LED, i tugged its cord so i had to open it further. i couldnt get the cord back to its "socket" so i had to remove the expansion bay part. puls the breadboard which contains the fuse and other thing which i dont know. i did all of this while the unit is unplugged of course, but my only mistake was i was standing barefoot on the floor. so as i was holding the breadboard, i felt a small voltage coming through it. then i payed no attention to it and reassembled the ps2. but when i tried to power it up, it wouldnt turn on!

so my questions are the following:
1. what is/are the cause?
2.any chance i can repair it myself?
3. if a fuse/capacitor is blown, can i replace it with pc parts?
4. how much will parts cost?

i read somewhere that if your ps2 doesnt power up but the fuse is good, it is hard to fix. i hope this is'nt my case. please help.... thanks in advance guys.
