So I just replaced my PSP Screen. I had weird vertical marks on my original one, so i bought a new one over at focalprice.com (Chinese internet store) with free shipping worldwide (i don't live in the US, so shipping is a big deal).
First of, the screen looks pretty legit. After I opened up the PSP (and managed to not figure out where a brown rubber thing that's supposed to go below the screen on top of the speaker is supposed to go, so i built it again without it), I switched the screens and lo and behold, my PSP is somewhat useable again.
The screen has a gouge on the left side of it, with kinda messes the image a tiny little bit (like, it has an atual scratch on the screen itself). It's not that bad, but it's a little distracting. I'm used to play my games all warped and shit, so that's not going to bother me much. just like my original screen, it has a stuck pixel. It looks like it's in the same spot, so I guess it's the PSP fault, not the screen? Anyway.
Also, the backlight doesn't look quite uniform to me - doesn't bother much, as my 24 inch LCD screen has horrible backlight and it doesn't bother me.
One thing that pisses me off the most is that i can't make the damn thing clean! I always notice a speckle or two of dust after i closed it up. I open it up, clean the screen, close again and it's either dirtier than before/new dust specs show up in it. Right now I decided to stop trying to clean it up even further, because the dust just multiplies.
Anyway, I'm quite pleased with the whole proccess. I wish I've gotten a better screen to replace mine with, but i'm pretty sure this one was up for sale because it has these issues. I rather buy one on Ebay, but as i said, shipping is a big deal.
It wasn't hard, other than the dust thing - man, I can never rebuild my portables without dust getting in.
