Both screens flash, then turn off

I'm attempting a shell swap on a DS Lite, I tore down the whole thing and now I'm trying to do a final power on test before putting the last few pieces together. When I put a known good battery in it and flick the power switch, the green power light comes on for a couple seconds, both screens flash white, then light briefly turns red before the device shuts off.

Both are new screens, and I tested with the old top LCD and had the same thing happen.

When I initially put this back together, I didn't realize I needed to insulate the rear of the bottom LCD and blew the F2 fuse. Today I replaced that fuse with a new one using a hot air station, so I'm worried something else might have been broken in that process. Before the fuse blew I was able to power on with both screens like normal. At this point I've triple checked all the ribbon cables, I've reseated the wifi module a couple times, and confirmed that the DS charges fine and the battery I'm using works fine in another working DS.

Given that both screens flash, I don't believe this is a connection issue with a ribbon cable. I couldn't find anyone else that had this exact issue so I'm a bit stumped now.

Thanks in advance, any advice is appreciated.

The board was indeed broken for other reasons. Ordered a working motherboard from eBay and installed that instead, all is working as expected.

Hi Zach!

When both screens are flickering, then both screens their ribbon cables are not all the way in/properly connected OR they are damaged.

The ribbon cables need to go all in the connector, when they are in, you actually need to carefully give them a light push to get them further in..

When the screens give you a white flash and turns off, it's always the ribbon cable.

Good luck with the repair, and let us know how it goes!

As mentioned I reseated these ribbon cables a few times. They're inserted as far as they will go. I tried again with both old screens and got the same result. All of these panels were known working on this board before I blew the fuse. I might try ordering a new motherboard just to completely rule out an electrical failure on this one.

Just to be sure you can try with a new motherboard yes! Maybe some component failed on it indeed..

New motherboard worked just fine. Looks like the original board has some deeper issues, unfortunately.

Okay glad that this solved it! Have a nice weekend!
