PSP won't read disks

from age or if someting is stuck in it

The UMD casing it broken and there might be a break in the disk itself. You need a new UMD game.

Not sure is this actual PSP or play station. If it is Play station It is very possible that there is problem with laser that reads disks. Try to by PSP cleaner and run it and this might fix the issue.

check the battery maybe it got messed up, or he didn't put the CD right

Replace the laser. This is the cheapest and easiest fix for this problem. You can get one of ebay for under $15

It could be that the outer casing is broken or the disk isn't spinning right inside the outer casing. I had this problem with a game my friend gave me. The case was broken so it didn't work. If the disk doesn't spin fast enough, it will cause a read error . I learned this also. I have seen replacement cases for psp games so you can always put the game in another case.

maybe the system is not working right why wont you take it to a mechanic that ccan help you

your son probably dropped his PSP at the time and the UMD drive broke or if your son says he didnt drop it you can get a cutip and softly clean your UMD reader the little bubble sorta in your PSP be carful while doing that

you have messed up the UMD drive or lazer
probertly knocked the lazer off the tracks

hope to of been of help

Put a umd inside wait a sec or two open and check if there is a red light, den the lens is fine its most likely that your cd has been scratched. Try using dev-hook or a custom firmware to read games from memcard
