I got a psp 3001 not too long ago and had it for a few weeks and its been working great! I decided to do a shell swap to fit with the theme i want for it. As soon as i hooked up the motherboard to power in the new housing I hooked up the screen to test it and worked great. I unhooked it and then continued hooking everything else back up till all I had left was the front face plate so before i put that on i decided to test one more time and lo and behold, the screen doesn't turn on!
I heard the speakers and was able to interact with the time and date settings but saw nothing. I turned off the room lights and held a flashlight to the screen and faintly saw it as i interacted with it so I've determined the backlight is the issue. I tried unplugging it and re-plugging it a few times to no avail so I decided it was likely the backlight fuse. I believe I found it after a lot of scouring the internet (small black square on the back of the motherboard labelled FB afaik). I took it apart to access the fuse and just connected the power switch (via the sensor for the x, circle, triangle, and square buttons), the power plug adapter, and the screen to the motherboard and I planned to turn it on and bridge fuse with some metal like i saw in this video to see if it turned on. Before I even had the chance, the screen turned on and worked fine. I was confused but I just put it back and made triple sure everything was plugged in snug and it once again DID NOT WORK when I connected it to power.
I have no fucking clue what the issue is ATP so if anyone knows anything or has any ideas I would be very appreciative!
