Crt Monitor Macer Model C708 as soon as i connect the power cable there is no power, no display

Have you checked that power is reaching your PC? First, check your power socket by plugging something else in. Next, you need to check the monitor's power line.If it has a fuse in its plug, check that by substitution if you don't have a test meter.It is very unusual for the power lead itself to get a fault because monitor power leads are heavy and of good quality.
It is possible that an internal fuse has blown, but if it has, there must be a cause. I would not advise you to even check that due to very high internal voltages even when power is off. Unforunately, CRT monitors are worth so ilttle these days that they are not worth repairing. Your best bet is to find a used monitor locally, which should not cost you much because they can hardly be given away these days.Look in your local papers.
