Psp Problem: Power wont turn on. but there's a light in Hold.

That might be the first documented case of the PSP getting a YLOD.

I'm sorry my friend, I'm not sure how I could help.

ylod= yellow light of death.. only happens on the ps3.. that yellow light isnt actually a light, its just a yellow thing to tell you that your psp is on hold lol. i think you should send it to the technician if none of the other solutions worked, the only other thing you could try is change your battery, though i doubt it would work

I guess that the battery may have shorted out and maybe getting a new battery will get it working again. But I don't really know. I've never tried running my PSP from the charger, without the battery installed, so to verify.

In that, if the PSP typically works without a battery from a charger, well, then you know that something is wrong with your PSP, because your's isn't working that way. But it may be normal for it to not work from the A/C cord without a battery. In which case... it may be the battery that has shorted and needs replacing.

Don't have my PSP near me, at the moment, to verify....
