Find a tv repair man who can check and change the capacitors inside the monitor. Half of the monitor problems around are due to a broken power source. Capacitors are cheap and easy to change, but at least here only authorized personnel are allowed to change them in AC devices. There's a bunch of other electrical components which can fail. Some of them are brand specific and thus very hard/expensive to find, some can easily be replaced with standard components. Dead backlight can be one reason for no picture. In that case the desktop is dimly visible at some angle. The monitor panel can also fail, often showing only a light stripe somewhere cross the screen.
So don't just throw your monitor into the waste bin without first checking whether it can be repaired or not. Big repair shops may not do such jobs, but a sole entrepreneur might. My choice would be an unemployed tech working for beer or pizza, charging only for parts.
