Depends on what's wrong, and how much a person's free time is worth.

The panel? No. The panel was the singular expensive part, and the cheapest and most available way to get a new panel is usually to buy it in a retail box with the rest of the monitor already wrapped around it.

The backlight tubes? Surprisingly enough: Yeah, if a person really wants to do that, and if the display uses fluorescent backlight, then sometimes the tubes are replaceable. (LED backlight is basically ubiquitous on newish displays and is, AFAIK, kind of a non-starter to dig into repairing. But it might be do-able by swapping bits from a broken panel if one were sufficiently motivated.)

Power supply bits? Sure. It's just a power supply, right? Power supplies are often repairable or replaceable. (I've repaired power supplies in LCD screens myself, and I'm pretty lousy at component-level troubleshooting.)

Broken connectors and switches such? Very repairable. (Difficulty depends a lot on how much, if any, of the board also got destroyed, but generally speaking hot air soldering is a lot easier than it looks like it should be.)

Mechanical issues, like a wonky stand or broken housing? Often repairable. (The screen I'm writing this with has a cast zinc base that broke due to metal fatigue. I've fixed it twice: Once with two part epoxy, and a second time by adding CA glue when the epoxy's grip on the zinc failed.)
