How do I fix this?

[CathalDublin]

Or more to the point is it fixable
The lines are there even with RGB plugged out
Dont really mind if its not easily fixable as I'll get a better newer monitor when Funds allow, this is just to tide me over
Have better pics but camera battery dead

difficult to say from the pic but i believe you have flyback lines,you need to turn down the screen volts on the flyback transformer
