Mac's a bit differant than windows. To change your screen resolution first change the monitors refresh rate to something like 75 hertz. Than you can change the Screen resolution. Thats how it is done on a windows machine. Than again your Mac might need a video card software update.

The term: "it has no power" is not specific enough. If the actual led indicator light on the front of the monitor lights up with a green color, then goes out or starts flashing, then maybe, perhaps the problem with the monitor is that the high voltage power supply for the screen backlights is not working. The common components that fail are the capacitors on the high voltage power supply board. If the capacitors are swollen or leaking, they are probably bad. You must replace a capacitor with the exact size of capacitance. You cannot replace with a "stronger" capacitor. You can replace with a higher temperature rated capacitor, if the capacitor will fit in the alloted space on the circuit board and in the case.

There capacitors would most likely be electrolytic type. They are polarized capacitors and used for filtering DC voltage supply to remove the ripply and smooth the DC power.
If you cannot get a 10 volt capacitor then you can use a higher voltage type provided it can fit on the circuit board.
