Okay, so here's my issue:

A week ago, I got sick and my monitor died. Now I'm better, and I've started looking into what's wrong. When turned on from any source (tried 2 different ones) via HDMI, there's a strange picture. To be precise, there's vertical lines in the bottom half of the screen. It seems those colors are whatever fits in the center of the monitor, so if you were looking at a blue square in a black background, it'd display it as a black background with a bunch of blue lines coming from the centerline downwards to the bottom with some blacks and differing blues in between them. The edges of the lines stop where the box ought to stop, and the lines will move if the blue box is moved.

So I pop the sucker open after giving it plenty of time to discharge, and I'm expecting to find a dead capacitor in here somewhere. But, after looking over all of them for any sign of bad caps (and getting someone else to look), nothing looks wrong in the capacitor department.

Is there anything else I can do to figure out what's wrong without any real testing equipment? I'm stuck without a multimeter or any parts I could swap in to figure out what's what, besides what you might have in your bedroom normally. I'm stumped.
