Power saving mode means the monitor is not receiving input. Assuming the Monitor is working properly, the tower is not producing the input or the cable is damaged. If the tower has another video out, try pluging into that. Try using another cable, if the problem continues that likely means that the computer is not working properly. The next step would be re seating the graphics card. http://www.youtube.com/watch?v=O9x097QRXeA
Simply remove then re-install the Graphics card. The device is very static sensitive and you should be sure to ground yourself before opening the case of the computer.
If that doesn't work it's likely the computer was damaged during the repair.
Or was not repaired at all, such is not unheard of; http://www.youtube.com/watch?v=WaZFGD0WJc0

It may be not sensing the video signal from your PC or it has problem inside the monitor, try it with another PC first, if it is still bad then you need to DIY repair.
