I have a side hustle I've been doing for about a year now where I buy broken psp, I fix them, and sell them to give the console a second chance.
This is something I'm looking to do too, i just bought 2 psps which are not booting up at all, and i'm planning to swap in and out the parts with w a working psp i have to figure out which component is faulty.
the two psps are odd, i assume that there cld be 3 possible reasons theyre not working in increasing severity:
1. the power supply board is faulty, in which case, replace
2. the super capacitor is faulty, in which case, remove or replace. seems like soldering is required
3. the motherboard is faulty, in which case i am screwed.
one of the psp i assume is the super capacitor the way it boots up sometimes and gets to the xmb and then dies, the other one has the green power light flash once for a split second before becoming unresponsive when i plug in a power supply or try to turn it on
i have a third psp i'm currently working on which is on pro c infinity or something and i wonder if i should install ark4 instead but i need to research on how and if it's possible at all. saw a thread earlier today on reddit that someone kinda bricked their psp trying to do that.
also it boots up really slow so i'm thinking if i replace the sd card will it be better cos iirc it's a no-brand sd card. probably slow read/write issues
