Title: PSP 3000 Screen Fuse?
Post by: Crumbz on February 02, 2011, 02:05:46 PM: I have a psp 3001 and am having problems with my screen. when i turn it on i can get sound but it it very shaky. and my screen refuses to turn on and if i shine a light on the screen i cant see anything. so i know it's not just the backlight.

Can anyone show me where the 3000 screen fuse is?

No im sorry to say thats not quite the same problem. and there actually is a fuse for the screen it's located directly underneath the sound fuse. bridging it with solder should fix it. (P.S.: Dont try and use Conductive Glue to fix it because the glue dosnt allow for enough power flow. It will leave you with a very very dark screen... i know cuz i tried)

also i DID get my screen working again but accidentally broke off my sound fuse and it ripped off one of the copper pads underneath it. is there a way to fix this? maybe bridge it to the screen fuse? or another fuse?

There is a backlight fuse.... No screen fuse.....
And wherever the trace that the pad leads to, you solder to the component where it ends. So solder a wire on one end of where the sound fuse was, and where the trace of the other side ends, solder to whatever component is there. If there is no component, scrape the trace until you see copper, and solder there.

The fuse is for the back light... if the back light is off, and he shined a flashlight onto the screen he would see that the LCD is still displaying images, there is just no back light to shine them thru.
