My PSP charges but will not turn on. I have switched out the power switch board with a working PSP. The switch board works fine. I have replaced the battery with a new fully charged battery and still will not turn on. I have no idea what step to take next.
Sounds like your motherboard is dead. Time to replace it. https://www.ebay.com/i/332686238029?chn=… PSP 2000 Logic Board Replacement
