PSP won't start correctly
I've had my psp for over half a year now and I'm pretty sure I know what I'm doing. But today when I tried to turn my psp on, it wouldn't start correctly. The light comes on but there is no display on the screen or any of the usual startup sounds. I'm running firmware 1.50, I tried starting it up with and without a UMD in the drive as well as with and without a MS in the slot. The closest topic I can find in the manual that adresses this would be a dead battery. I'm recharging it now just incase but it has not helped thus far. Taking the battery in or out also doesnt help. Once the psp is on I can turn it off but it takes about 20 seconds longer than it should but I can't put it into sleep mode. If anyone has any ideas it would be much appreciated, I just dont want to replace the battery and find out my whole system is ruined, not just the battery.
