Can anybody shed some light on this situation? I really don't want to have to buy a new screen.
"Removed" the two fuses? Last time I checked, you were supposed to bridge them.
Oh, and I discovered a new way to input voltage to the screen without touching that stupid tiny fuse. I traced where the 7.2v line goes, and it leads straight to the fuse. But I hate the fuse, so I kept going. Turns out, it leads to a SMT Cap. You can input 7.2v into one of the contacts there(don't remember which, no psone screen right now), bypassing the fuse completely, and allowing yourself a bigger contact to solder to. I discoverd this when I had already attached my screen in on #5 and could not get to the fuse, so I got one of my new boards and multimeter'd it.

Hope this helps!

Well, yes, you are supposed to jump the two fuses, but I removed them to make sure there were no shorts.
That may help, I'm not sure if it will, but it is still good for reference. Thank you.
Actually, it's back to life. I just forgot to update this thread. I bought a new screen for it and installed it. Look for a video soon on my Instructable!

I thought this looked familiar, your instructable is the reason that I came back to this site. It's inspired me to start work on my SNESp.
Great job by the way, on the instructable and the NOGO.
lol, you joined yesterday

I think we should check to see if you can withstand 220 volts
