Broken Pelican PS2>PS3 adapter

Mods, I tried searching for a topic about this, but I can’t use the search function for a long time…

Anyway, as the title says my Pelican adapter is broken.
It still works occasionally, but sometimes it won’t power on when connected.
Sometimes it’ll also light up for a sec, but then shut off.

Any ideas on how to fix this?
I remember reading up on the trade forum on how someone replaced the USB cord for a better when. If that’s all I have to do, anyone got a guide or tips on how to do this?

If this turns out to be beyond my skill level, I might just sell it as-is…

Ok, I’ve opened it up and took some pics.
I think the main problem is with the cord, but I want to make sure.

The front

The back

So do the insides look OK? Just want to get a heads up from SRK before I do anything drastic…
