Is your PSP modded in any way? If you power it on with the battery out but the charger cable plugged in do you hear any sounds if the volume is up all the way and you press buttons?

If it’s bricked there are ways to recover depending on what motherboard revision you have. If you have an older one you just need a Pandora battery and a memory stick programmed with Despertar Del Cemeterio v9 so you can have firmware 6.60 installed. If you have a newer motherboard then you need a Baryon Sweeper battery and afaik you can use regular memory sticks but they will need to be modified with the newer ipl.bin to work with a newer motherboard.
Pandora batteries and preprogrammed memory sticks can be bought but I don’t know anyone selling Baryon Sweeper batteries and you need to have decent soldering skills just to assemble them and good computer skills to use them or program them depending on the method you choose. I’m still waiting on parts to arrive so I can make a Baryon Sweeper battery to fix my 3001 that I purchased bricked. I was Planning on making some to sell but they’re going to be around $30-$40 or so before shipping depending on the price of the parts at the time.[br]
