Gaming Psp 1000 japan bricked

[pinop]

Hi guys, I have a psp 1000 japan model that seems bricked: green led turns on when power on, but black screen and no sign of life. So I prepared a magicmemory with cementario v8 and a pandora battery with my other psp fat, and I tried to unbrick the japan one. But when I insert the battery, pressing L button, the green led turns on for 2 seconds and then turns off. The procedure of memory and pandora was done right because I tried it on the other psp. I thought it was a problem about reading the memory stick, so I switched the slots of the two psp, but the problem still occurs.
Any suggestions ? Thanks in advance

What does it mean that it seems bricked? Don't you know what happened to it? Did you buy it that way already? If so, it's not necessarily a software problem; it may very well be hardware damage, whether it fell, took a hit, got wet, or got ambient moisture.

Hi, thanks for the reply. A friend of mine gave it to me after many years of no usage, and he does not know what happened but the behavior(green led but screen response) matches with a bricked one; so that why I said 'seems bricked'. And yes, I m also starting to think can be a hardware problem of the motherboard
