Alright, so a while ago my dslite's top screen started getting white lines on it. It then stopped working completely cause i had to hold top part up due to a broken hinge. I replaced the hinge, except the top screen was still broken. So i then tried replacing the top screen. I don't know much of soldering, so i didn't reattach the speakers. I reassembled my dslite, and tried turning it on...but then the green light turned on but shut off immediately. I figured it was a fuse, so i wiped the f1 and f2 fuses with some isopropyl alcohol (70%) to clean up the muck on them. I heard alcohol can make electrical contacts communicate better so i use this method to clean the motherboards on my lite and psp. Now the green light stays on when i turn it on, but the screens still won't come on. I don't know what to do now. I know the top screen is brand new and the touchscreen works. (though the p6 ribbon is a little bent) I get the orange, charging light when i plug in the charger. I cant listen for sounds because i couldn't use a soldering iron for the speakers. The backlights aren't turning on either. What do I do now?
