Similar monitors go for under $200 and I suspect a repair center may charge more.
Possibly you might be able to repair it yourself. A tip over or fall can knock loose connectors or put the HDMI pins or cable under stress
sanity check: If you connect another monitor (or tv with HDMI) to your PC does it work? Try a different HDMI connector on monitor?
some help on disassembly

With your damaged monitor connected to your PC and the PC turned on shine a flashlight on the screen and see if there is any background image of the windows login screen. If so then the problem is the backlight
Does the monitor have an LED that shows power is connected? If it is not lighting up possibly the connection was knocked loose and there is no power getting to the display board.
You are going to have to disassembly the system. Depending on where you live some technical or trade schools will do repairs at no cost other than parts as their students need the experience.
