Repair: Not reading UMD discs
I have seen many PSP's stop reading UMD discs and for the
most part they are repairable with the least amount of opening your PSP.
About 35% of the time I find that there is
something stuck in the UMD gear. It is different every time, sometimes its a
piece of dust, plastic, soda, and even hair.
So first what we need to do is find out what is actually wrong with your PSP.
With your PSP in hand.
If you look to the left there is a black tab that sticks up, this tells the PSP that there is a UMD in the drive.
If you press this down with a small probe, you should see
the disc motor spin and the laser light up red
If the Motor is not spinning. is it moving
slightly? Maybe a little twitch?
If the laser is not lighting up then it could be the laser, I would try and check the cables to the PSP and see if there is a bad connection.
If both are running well then lets put a disc in
and get your ear up close so you can hear what is going on in there.
Can you hear the disc spin up? If not I would take the disc out again and press the switch with your probe again. if the disc motor is spinning again, look around to see if the metal housing is obstructing the disc when you put it in.. there could be to much pressure for the disc to spin freely.
Can you hear the Laser focus? This might be hard to hear it will sound like a little tick. If you cant hear it tick I would move on and inspect this internally later.
Can you hear the Laser move down the rail? This
will be a smooth sound of the gears, it should not be a really clicky sound.
After this try and see if it is reading UMD again.
This fixes it about 35% of the time.
If none of this is working, it is time to open your PSP unit Or send it in for repair.
