So i have this Hitachi monitor, and every so often the screen just goes black. The power is still on and its not in standby (Green light is still on), and the only way to get back to an image is to press the power button off and back on. Wiggling the mouse and keyboard does nothing. It will happen anywhere to from every 1 hour to 10 minutes. Ideas?

Well, as you no doubt realise, the monitor is faulty. It's hard to say much beyond that - we could guess as to possible causes depending whether it is a CRT or LCD monitor. A common likelihood is a bad/dry solder joint or joints, either in the backlight inverter if LCD, or heater, video drive or a supply rail if CRT. But equally the cause could be something else.

It's an LCD monitor. IF it is a bad/dry solder joint(s), are these repairable? Either by me or a computer store? Or would it just be cheaper to buy a new monitor?

If you have appropriate soldering skills and equipment, soldering over an inverter/power PCB is a task that could be tackled at home, or it could be done by a repair shop with the inevitable cost. A lot of people do use something like this as a prompt to update to a new monitor.
