Chosen Solution
I found my old psp in his box, I decided to load it to play because I missed him, but then when I loaded it for a while I decided to turn it on, but the green light on the power was on and the psp did not appear on screen, Connected, until I tried to turn it off normally but it did not work, I had to hold the power for 5 seconds to be able to turn it off, does anyone have any idea what problem this is? , Already tried with the charger connected in it without the battery but also did the same, also took the mdstick and the problem continued
If it turns on and the light is working, than the problem can be the faulty screen, try replacing it firstly.
