0.01v instead of 33v

[lenselijer]

I measured the Backlight connector and the pin to the right has 33v on a working psp, but on my psp it only has 0.01v.

Can someone help me fixing this problem, i dont really want to buy a new mainboard :P

I think this is the fuse for the backlight Check it with a ohm meter it should have (0) resistance. If it is infinate than the fuse has had it.

Thank you so much!

I measured the fuse with my multimeter at Rx1 and it gave no output. Then I tried the other 2 fuses and they did give output.

So my Backlight fuse is dead. Can I remove it and put a wire instead? Or will it kill my whole motherboard?

I just went ahead and soldered a wire over the fuse, and guess what, backlight is working again :D

thank you once again!

There are 2 other fuses, 1 for the USB and 1 for the Power, please check them both if they are still OK. If not, bridge them too :D

It's a very easy fix for the backlight, my PSP is working like new again :D
