error no signal input or cable unplugged - this means the monitor is receiving no video signal from your computer's graphics card, and the cable it's referring to is the thick one that connects the monitor to the graphics card at the back of your PC.

I think your monitor is fine. It's the PC that's the problem. There's a "power supply unit" (PSU) inside the PC and that may be faulty.
Whatever it is, you'll need to get it looked at by a PC repair shop as it could be any one of several things.
Sorry, but there isn't a "quick fix" for this kind of hardware error, you'll need someone to look at it who knows there way around the inside of a PC.
