PSP 2003 will not turn on.

[Baggervance]

First off hello all and hopefully one of you clever chaps or lasses can help me out.


Now on to the problem

My daughters PSP a slim 2003 originally flashed with 3.71M33 using a home made Pandora battery and a boot mem card, then over the years updated as needed, finally flashed with 5.50 gen d3.
It was working fine, over the few years she had it. But as time went past it was just left on the side (in a padded case) and not used for probably 9 months.
She come to use it yesterday and obviously the battery was very flat. Charged it up no problem

What happens is you turn on the psp, the green light turns on and nothing else happens. Then the green light then turns off after about 10 seconds ish.
It does exactly the same with the battery removed and using just the power adapter.

I dug out my pandora battery and card which I made all those years ago, charged it up.
Put the mem card in, put the pandora battery in. PSP turns on automatically like it normally does with the pandora battery, but it makes no sign of reading the mem card ie the mem card access light don't even blink at all.

Ive since tested the card and pandora battery in a friends 1000 series, it works still works fine.

Any idea's what could of happened

Many thanks

Interesting.............are you holding down the correct button ("L" Trigger) while you try to use the pandoras/MMS combo?

Hi, thanks for the reply.

The boot card in question doesn't require any buttons to be held down.
Card in, battery in and it boots straight to the recovery menu. Confirmed in a friends 1000 series PSP

Although I have tried holding the "L" trigger. Just in case.

I cant imagine that the PSP went bad from non use. It could be that the power board went bad. Are you in California?

[Baggervance]

Unfortunately not, I don't think I could be much further away as I'm in the UK.

What do you think is the problem with the power board and any way to test this.
Don't worry about getting technical as I used to do allot of console repairs in the past.
Just not familiar at all with the internals of a PSP.

thanks again,

Had a bit of time this morning.
I've stripped the PSP apart visually checked the motherboard over. every thing looks OK no signs of mould or corrosion.
While I was at it checked all the on-board fuses, all which check out OK.

Rebuilt it and had a prod round with my multimeter. The board seems to power up when the switch it pushed and obviously powers down when the green light goes off. But as said I'm not familiar with the internals of the PSP.
Are there any places I need to be specifically checking?
