Crap I burnt it...

I was doing an install on a v7 with a duo2se. It was getting late and and I was down to the power wire. I must have held the iron on the brown fuse a little to long. It melted the corner of it alittle. I didn't think much of so I just continued on, put the ps2 back together and turned it on and nothing happened. No video and it would only eject like half and inch when i pressed eject and reset. So I had another v7 board sitting here, i desoldered the brown fuse for the power and the ps4 fuse and replaced them. The ps2 turned on ejected fine and played originals and ps2 dvd backups fine. However now when I put in a cd base game the drive makes some wierd noises like the disc is out of control. I can't get it to boot ps1 discs but it will boot my snes station disc.

Anyone have any ideas?

do you now that you have to press standby until the blue led turn´s on.
that´s the way to play ps1 boot.
