So, I’ve got a laptop screen that’s giving up on me. 2/3 of the screen runs alright but the 1/3 on the left edge is acting weird. Half of the broken section displays an image but the image smudged and weird, while the other half is just dead. I opened it up to see what’s up and, lo and behold, a wee tiny capacitor is missing (I know it’s a capacitor 'cause I looked of the board marking, C248).
Now I’m wondering, since ordering a single capacitor just for fixing this screen is not worth the effort, can I just… put some solder in there to at least get power to where it needs to go? I know it’s definitely not ideal but, this is an ancient laptop. Putting in the effort to fix it perfectly is not exactly a great value proposition. What I want to know most is, will the screen be damaged if I do this, or what could go wrong if I do this?
I’m pretty new to DIY electronics fixing so sorry if this is a stupid question. Thanks in advance y’all. Cheers!
Shorting where a capacitor was won’t provide any power, it will most likely cause a short circuit, potentially resulting in sparks and flames.
It can let the magic smoke out, yes.

I think you’re trying to clarify that shorting where a capacitor goes won’t provide any useful power.
But electrons will certainly flow and do things.
In useful terms, there will be no useful power. In safety terms, there will be some dangerous unexpected-by-the-designer-of-the-circuit power.
Sure, it won’t provide any power to the circuits that are supposed to get power was the intent of my comment.
