I have a PSP 2001 with a TA-085 MOBO.
A while back I did a speaker and LED mod. Nothing special. Yesterday I took my UMD door off with the speaker. I left the wire in the back unprotected. I was playing a game and everything was fine. Then I set my PSP, still on, onto my bed. I came back 30 minutes later. My PSP was very warm. The right speaker crackled when music is playing (It is blown. Other speakers sound fine).
I disassembled the PSP inspected and reassembled it. No audio out of headphone jack or speakers afterwards. Opened it up again and bypassed the fuse. Now everything is almost fine again - except the heat.
I noticed when the fuse was blown, it was nice and cool. Could this be the opamp or audio processor (if the PSP has one)? Is there any hope of saving it? This is really hot to the touch. Not within safe limits.
I can't believe I was so absentminded. I would really appreciate any help or advice. Thanks you.! :
