I'm new on this forum; as I said on my presentation, I usually spend my Sunday in a flea market here in Milan, and so I was 2 days ago, when I suddely saw a sort of uncommon blue playstation 1 on a shelf and, knowing little information about it, I approached the vendor to give it a glance. It turned out it was a "Debugging station" I had only seen from Wikipedia, and happily bought it without caring about reducing the price (a modest 10 euros).
Judging from the pictures on the net, my blue playstation is probably the one in the worst shape. First of all, the case is "tanned" by some intensive exposure to the sun, and then more serious problem: it doesn't work.
There are writings that inform me it requires 12V DC delivered by a specific adaptor, which didn't came with the console, and is now unfindable: I tried to connect it through an iPod docking station adaptor which was 13V DC (One Volt more never hurt anyone, am I right?) and the blueish thing didn't show any sign of life. So I unscrew it and I found out that the very first contacts, I'm saying the ones that connect that unusual dock to the PSU board are unsoldered. I tried to replace the whole PSU with the one from my SCPH-7502 but the wires are different in shape and numbers.
First of all, I would ask: having the solderings repaired, is there any danger delivering the console 13 out of the 12 Volt it requires? And then, what kind of PSX should I look for to get a compatible PSU to check if at least is something working inside the thing?
I thank anyone who's got patience enough to explain me (who am quite unexperienced about PSX and other consoles) what I may do to bring this "broken gem" in working order.
