Tried to replace the screen on my T450 and now have no backlight

[anything]

Hello everyone, I've owned the T450 for a while now, absolutely love the keyboard on it. I finally decided to upgrade the terrible 900p TN panel to a 1080p IPS one (LP140WF3-SPD1) so that I can use it as my primary. Got the panel yesterday and in all the excitement forgot to disconnect the battery before actually removing the edp connector and replacing the screen. After a bit of research, I believe the fuse that limits the power to the screen is blown (F7?). Around the internet, I have seen many people who had a similar issue, which they managed to fix by either replacing the fuse or by just soldering short the fuse, but I didn't find a single photo of the fuse in question (F7?).


Now I am posting this just to confirm my views on the issue, before I actually open the whole laptop up and screw something else up. Am I missing something or should I go ahead and solder the thing?

Yup, just solder it, no problem. Most other manufacturers have nothing between main power and LCD connector anyway.

Better have the fuse blow than have the PCB or the LCD connector turn into smoke or flames when something goes wrong.
