Hello everyone,
I was all of a sudden irritated yesterday when I remembered that we have an LCD monitor that had failed some for unknown reason and that at the same time we can't bear to have it sent off to landfill or some e-waste distopia. I resolved that I would much rather repair it and learn a new hobby in the process. At the moment, I have a beginner understanding of circuitry, componentry, and saudering, but I'm keen on learning if I can get this thing working. Though, the question remains whether it is a lost cause... I hope someone might wish to provide insight.
The current situation is that the monitor will not turn on. The AC adaptor green light is on, as is the green light on the logic board. By my view, all the capacitators are their normal shape, no bloating, leaking, or off-colored logic board. Before failure, there was occasional distorted image in the form streaking lines.
This probably involves much more than I know. I guess what I'm hoping for is that someone has experienced the exact same thing, and might suggest next steps, or whether it should even be attempted by a beginner. I spent some time on the forum looking for similar cases, but they typically involved visually obvious failed caps.
