monitor goes black and if you push on off button screen comes back on then immediately goes black again.

One of 2 things can cause that, the inverter or the back-light. Inverter is cheap to buy if you can do the work of replacing it it. If you need to pay some-one for this, you are better of spending the money towards a new monitor.
