Hi, I have a v5 plain ps2 and alas, I have opened it to check out the soldering points. I have fixed it back together again (i haven't soldered anything, just checked) and when playing Tekken 5, the noisy ps2 has silenced itself for once. Yay, I thought, until 20 minutes the tv went all black showing no output and the lights on the ps2 blinked red so I turned it off.
I then found the ps2 to have killed the fan (supposedly) because after dissecting it, the wire connecting the fan to the ps2 has 2 melted points. I have ordered a new fan to try and fix it. The ps2 still runs fine without the fan though (and I mean everything, from ps1, dvd, ps2 except network adapter in which I don't have), for up to 20 mins, so I think the cause is that I stupidly didn't place the fan wire back in place correctly. Is this true? I'll post again once I know if the ps2 is fully alive again.
