Loss of audio Output From Units speakers.

Hi,

I have my psp go doing an odd thing.

It powers on fine and all functions are correct - save one. Audio.

Initially i susected that the device was assuming thati had headphones in - but when headphones are inserted the volume changes ion screen to the volume i had set last for headphones and audio is outputted through the headphones.

I then suspected that there may be dirt in the dock and thourghly cleaned the dock. Still no sound from speakers.

I then stripped PSP down as per your guides and looked at the speakers themselves - visually nothing "seems" wrong.

What areas should i be focussing on to rectify this fault?

Is it possible the speakers have blown after a heavy bout of dance/trance bass?

If so where can i obtain replacement parts?

Thanks in advance

Coxy

-EDIT-

Reading other psp go problems i found this fuse diagram.

Anyone care to share a translation?

SOLVED

It is a piddly little fuse on the right side of the motherboard as you remove rear case.

It is marked with the letter L.

My fix is more of a bodge tbh.

I desoldered the fuse and used a bit of thin wire to make the circuit.

to make the fix permanent i need a new fuse lol.

Anyways hope this helps someone out in the future

Great job, now all you have left to do is to accept your own answer. That way we will know that this works. Again, great job.

Fuses blow to protect the rest of the system. By bypassing it you risk serious damage

Here's what mine looks like (I desoldered those three little fuses):

When I get some thin wire soldered over the contacts to make the circuit, the PSP stops booting up. I take it off and it goes back to working (yet with no sound).

This is literally my first time using a solvering iron, so I'm wondering: is it possible that my board has gotten so messed up to the point that I'll no longer be able remake the circuit? Or am I just not soldering the contacts together correctly, and therefore should keep trying?

^ you might have not have done it correctly.

Make sure you didn't leave any residue around the components. It can cause faulty things to happen.
