these psps have never been dropped or sat or or misused....
both of them started this at the same time...first as a tiny spot then spreading into what you see...both in similar areas...
ive never opened these psp before this issue began, and i thought it was dirt on the lcd so i opened and wiped them clean carefully...it looks like its INSIDE the lcd on the backlight. but im too afaid to try and split the lcd from the backlight...
any information on this and possible ways to fix would be much apprecated...
couple things to note, you can only see then when theres bright colors, also, when you tilt the psp it actually makes the spots brighter then the rest of the screen.
here the pics.
