My psp CFW 5.50 Prome-4 Slim, recently has a problem with both lights: WLAN and the memory card lights are always on, even if I shut down the PSP. The only time both lights would turn off is if I remove the battery. Before it was just the memory card light always on and orange. Now it's the green WLAN light, no blinking. I tried the memory card on a FAT psp without a problem. I even tried to reformat the memory card itself via my computer and even on the psp, but with the same problem. I've never dropped it.

Any ideas or solutions?
