PSP screen shake then line

[kabuto202]

So after playing Blazblue for a while on my PSP, I set it too sleep and turned it back on again. My screen began shaking uncontrollably and I thought whatever, if I ignore it it'll go away. After a while I decided to open up my PSP again and dig in all the way to the mother board/joystick connecter to try and fix my joystick being undetected problem (And I did ). Then I put everything back togeather, and turn my psp but, my screen continues to shake, during the next 5 min or so, it gradually begins to slow down and then stops. However I'm left with an annoying gradient line on my psp on the at the top from left to right. The it goes from white to grey, and at the left end of it, it flickers between white and grey.

Also, I've previously experienced distortion with my screen for a few seconds after turning on my PSP when, everything looks like it's pushed down to the bottom of the screen.

It's M33, slim 2000.

Umm, loose cable? Or firmware probs, you never know.

I'm not sure if it's a loose cable cause while I have taken it apart before, it only appeared today BEFORE I took it apart. If it's the firmware, I wanna be %100 sure, before I wipe my PSP clean.

So I reinserted the PSP screen, and then reinstalled the firmware, problem still persists.

Damaged LCD? It's either the LCD or the motherboard which causes the problem. The rest shouldn't even affect anything. Ever dropped it? I've heard Sony made some crappy LCDs... I fixed mine by setting on a "Pixel Fixer" for like an hour and voila. No lines til I dropped it so I just took out the faceplate, resat the cable and done. I srsly don't know how a pixel flasher would help but it did.
