PSP won't start up

I think you may have gotten it wet somehow. Were there any drinks around it?

If you are playing games from custom firmware then follow these steps:-

1) take out your psp battery
2)put on charge direct from charger(make sure the battery is not in psp)
3)turn on psp holding right trigger to move on psp recovery menu.
4)reset all flash settings(it's somewhere in advanced tab)
5)after resetting fullt turn off psp and put psp battery in and turn on here you go.

i think youll need to call to get service done............if your psp warranty isnt up they may give you a new psp

keeping Lithium ion batteries(found in ur psp) idle for such a long time without charging may discharge them compleatly and even if you try to charge them they will not function. this seems to be a problem with your battries not ur PSP. try to get it replaced from the dealer you bought the PSP from. hope this solves your problem.. :D

do you install custom firmware? coz if you do maybe it got brick. try using pandora battery if it works. if it still dosen't works you may have a hardware problem.

did u format the memory card from the psp? if yes then remove the memory card and then try to start the psp if still not starting then remove the battery umd and memory card from psp and leave it for a day and then try inserting only the battery n make sure that thee is enough charge left on the battery
and if still the problem persists then plz tell me when u connect the charger does the charging indicator glow ?

maybe the main problem is the unit or the battery itself, go to the sony repairing shop so that they can replace it or fix it. thanks

maybe you have to change your psp!

this happened to me and i think it happens when you play your psp while its charging too much, i got littlebigplanet and i love the game too much. ive been playing it 24/7 (not really) but ever since i started playing it while it was charging, it would do this.
