SOURCE: PS/2 power supply connection
You seem to have an oddball monitor if what you describe is correct. The power supply to a monitor[Display Screen is that what you mean?] is either direct to main power- in which case the power cord is either built in with a power plug for wall socket, or has a socket on the back for a separate main power cord. Or is powered from a low voltage converter that delivers low volts usually via a coaxial plug like this illustration PS2 connection does dot come into the equation as far as I know unless you have got hold of something unusual. Tell you what take a shot of the back of the monitor and lets have a look see mean while here's is a shot of a typical low voltage power supply available anywhere.

The 7812 device is a voltage regulator. Either the reg has failed or the input to the reg is no longer approx 12volts. It should be more than 12volts so that the reg can control the o/p .

This could be a back-light problem, it can be caused by a faulty inverter board which supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro tube.
