Psp power switch broken - Sony PlayStation Portable (PSP) Console

It seems that your PSP's power switch is broken. Make sure there is nothing blocking it from fully switching "on". If there isn't, it needs to be repaired.

Inside the PSP the switch has a small pin that engages with the switch. Likely this pin has broken, or has become disengaged with the switch inside the PSP. Take the back off the units and have a look... be careful and make sure you note where each screw goes.. and reassemble the same way- its not hard..
Good Luck

It may make a person without hardware experience a bit nervous to do, since you'll need to disassemble part of the PSP, but it is not all that difficult. Of course if your PSP is still under warranty, might as well get Sony to fix it. Otherwise, doing it yourself should take 20-40 min. This guide shows you some of the steps you will need to follow:

From that guide, removing the power switch board only really requires steps 1, 2, and 6. In summary, you need to unscrew 5 screws to remove the back plate, then pop off the bottom button bar, and then disconnect the 2 connectors from the power board, remove the board, and swap the new board in. If you have trouble reconnecting the large motherboard connector back to the power switch board, you may need to remove the LCD as well.

Dealextreme has a good price for the power switch circuit board part: http://www.dealextreme.com/details.dx/sku.2766

You can buy a power switch circuit board replacement part off of ebay for under $5 (typically shipped from China). Buying the circuit board is easier than buying only the switch, since it avoids having to do any soldering. The power switch board can easily be swapped out and a new one reattached by connecting a few connectors.

You should get it fixed. You can get it fixed on ebay.com just type in psp repair and you will see people who fix them.

you need a new power swich ? which you can perches of ebay

ebay is your friend for parts, but google is best for instructions.. you can even try youtube for video instructions.. Make sure you reread any auction twice for your own protection.. and use paypal for the transaction.. Hope this helps.

I think you have a real asshole for a friend. Sue him.

The power switch has been dislodged from its mounting.
The switch will need replacing and you can find one easily and cheap on an internet auction site.
