To answer the original question- yes it is possible.
I know for a fact that you can use a TUBE from a TV to replace a TUBE in a monitor, but you have to know what your doing, you can't just use any tube, and there is some work involved.
Not easy to do, easier to just buy a new monitor. And no I have no clue how to do it.
