Backlight won't work. My question: Which Fuse do I need to bridge?

Hello, my question is in the title.

The PSP (Mod. 200x) is operating completely normal. It was unused for many years now and when I turned it on the display was apparently not functioning. After I shone some light on it while on I could clearly see that the problem was not with the display but with the Backlight. I’ve read that many people just bridged it with soldering metal and it worked just fine so I want to bridge the fuse too but in order to do this I need to know which fuse exactly I need to bridge.

I will add some pictures of the Mainboard. What I’ve done: I disassembled the whole console, cleaned most contacts with Isopropyl Alcohol.

It’s confusing because I have seen many videos but most of them are with the 100x, 300x models or the PSP Go. And the sources I found on the 200x model (which I have) always mean different fuses to be bridged/fixed.

@spicylemon I would not suggest to bridge the fuse. That will only destroy the rest of your circuit if anything goes wrong. Just replace it.
It’s just as much work to solder a component than a jumper wire. the backlight fuse is F4101 which looks like somebody already removed on your board. Go ahead, REPLACE it.

Hey, thank you for your advice. I really never violated the Mainboard so that’s quite surprising that there is a fuse missing. I’ll solder it and let you know if it helped.

I wonder how that fuse could possibly get off from the Mainboard if you have any speculation why that might happened then let me know.

@spicylemon if its your PSP and has never been "opened" it is possible that this fuse just popped of due to bad soldering. It does happen.
