If your 3000-series PSP is having issues not turning on, this guide will explain how to replace the circuit board for the power switch.
When the power circuit board functions properly, the light next to the power switch should be illuminated after the PSP is turned on, even if there is no audio or video. A faulty circuit board can prevent the device from drawing power and beginning the startup sequence
PSP batteries have had reported issues with swelling, so remember to visually inspect the battery cover for bulging before removing the battery. For more information on swollen batteries, click here.
Before getting started with this guide, ensure that the problem is actually the circuit board itself. Follow this guide up to Step 10 to disassemble the PSP, and inspect the switch to make sure the power button on the case activates the switch on the circuit. With the screen removed, also ensure that the silver ribbon cable has a firm connection both on the power board and on the motherboard. If the cables are loose, then they can be secured with electrical tape underneath the cable and away from the connectors.
