You might have a problen with your laser lens, umd drive or umd its self. do any other umds work?if not and you still have a warranty i strongly recommend you get a new one before your warranty expires, if youd hate to send it back to sony because they might give me you the new PSP that cant be downgraded, you could just open up your PSP and clean the UMD drive (once you open your PSP the warranty Expires straight away,so that wouldnt be something i would do)if you still want to do it follow this simple steps.
1. How to open your PSP
One small size Phillips Screwdriver, if you dont know what that is you should probably not try to open your PSP, ok its something that look like this X
On picture 1 you will see the 5 screws that need to be removed to open the PSP, marked with red arrows. If you are not going to remove the whole inside of the PSP then dont bother to remove the 2 screws marked with green arrows. There is also no need to remove the whole label inside the battery compartment. I just did it for this picture.2. How to remove the LCD screen
Its quite easy to remove the LCD screen, just use a small flat screwdriver and put in the side like you see in the picture and pry it open. Now dont slip, you dont want to put a big scratch in the LCD screen.
Now it will look like this, and you will see the screen is attached with 2 orange flat cables. Always be extra careful when opening this type of clips, they can very easily be damaged.3. How to fix stuck L/R buttons
This is how it looks like when you have the stuck button problem, its not very common, but I have seen it a few times. Fortunately its easy to fix. It should be noted that Sony have fixed this issue as far as I know on new productions, so new comers shouldnt be worried about this.
Before you start doing this, check what part of the plastic that actually get stuck and then just use a nail file to remove some of the plastic, put it back, test again if it still get stuck. If it does then file down some more, but be careful not to remove to much or you will end up with a lose button instead.
