It sounds as though the power supply for the monitor has a problem - it may be a capacitor that is failing. It is obviously trying to turn on but the voltages are not right. The simple solution may be to replace the power supply board, but take it to a reputable electrical/electronic repair man.

Sir,
there could be two possibilties for that
1 That your serial cable is not working or have broken pin .
&
2 Another is that you monitors picture tube has got damaged or burnt.

Usually it is second reason it can be repaired but is more expencive so i would prefer buying new one.
