I did this kind of a repair job to a couple of Samsung 23" 1080p screens back in 2012. A friend gave them away since their backlights would flicker making the monitor unusable for the first 10 or so minutes after they were turned on, after which they worked completely fine. I have little to no knowledge of electronics, but did know how to use a soldering iron. As I recall, I watched a YouTube video and was confident that if the problem was just the capacitors, then I could manage to replace them. I opened up the monitor, saw two or three capacitors which were clearly bulging and I used a soldering iron to get them off the board. I went to an electronics shop expecting that someone there would be able to advise on replacements which would work. As I recall one or more of replacements they had available on hand had a different "number" on it, but they assured me it was a higher rating and wouldn't affect use, I don't know much about electronics, but this made sense to me so I trusted it. I managed to re-solder them on and they then worked perfectly. Fast forward to today, about 9 years later, and my brother is still using both the repaired monitors. They have DVI input, 1080p resolution and VESA mounts so are actually very decent unless things like >60Hz refresh rate, higher resolution or very good colour accuracy are important to you.
