Recently, I started using dollar store headphones (sony ones stolen). They worked fine for a couple weeks, but then they made my headphone jack move in towards the psp. I moved them back, but now sound doesn't come out of my psp. My dad bought me it, but never got the warranty (he thinks its a scam), and it's been 2 years since I bought it anyway. I can only hear sound through the headphones, but not with speakers, and for the headphones, I need to jiggle them a little bit. Even then, it only come out through the right ear. If anyone can help me fix my psp (confident it's a hardware problem) then please. I would prefer to do it myself, rather than send it out and be charged money. Any help would be greatly appreciated. Thanks in advance.
