Bit of a tangent but maybe this a good place to ask: I've been trying to diagnose a weird display issue on my 4K IPS monitor. It seems to have a stuck pixel, which looks bright green on a dark background. But weirdly, the pixel changes color if you move your head from left to right, cycling from bright green to hot pink to purple and then back to green (though it doesn't change color when moving your head up and down). Also, it seems to "float" slightly above the actual pixels. For ex, if I open a paint program and draw a straight vertical line directly adjacent to it, there's a gap when looked at from the right, but it seems to overlap the line when seen from the left.
Anybody experience an issue like this before, or know if it has a fix? I've searched but only find discussion of regular stuck/dead pixels.

And this is about CRT monitors. Is there something like this for the LCD monitors we all use today?
Is it economically worthwhile to attempt to repair them? They seem to be generally reliable, and replacements of any kind are cheap. Certainly cheaper than having somebody else figure out the problem and probably cheaper than having you do it too. Especially once you add in any equipment involved, multiplied by the likelihood (low) of having to do this repeatedly.

In a developed economy, maybe barely. Depends on the monitor, and what's wrong with it. If you're good enough at soldering, and it's just a capacitor in the power supply issue, and the case isn't going to fall apart when you open it, sure. But if you have to hire help, or replace a module, probably not.
In places where skilled labor isn't going to billed at $100/hr or more, then there's more you can do ... I don't think it's worth replacing a panel if the panel (or its wiring) go, but you can replacing modules likely makes sense, if you can source them; maybe some light module repair too if it's just cold solder joints need rewetting.
