To tell you the truth, just about any repair on a monitor is an expensive
repair, at least compared to the current prices of new ones. Although I had
one monitor that simply blew its internal AC fuse, but that is obviously
not your problem (since it has power). NEC monitors always have a clicking
sound when switching resolutions, they use relays to select different
components in the circuitry for different resolutions.

Your monitor, from the symptoms, has lost its horizontal deflection, that
is why you only get a vertical line. Since you have vertical deflection,
and a beam, it is likely that the horizontal flyback is working because
usually the high voltage for the anode is derived from the horizontal
sweep. It is then most likely either the horizontal deflection amplifier,
or the deflection coil (located on the neck of the CRT tube itself). Either
one is probably expensive, compared to todays available price of that
monitor of $220. Just about any repair starts at $50 to $75 just to have
someone look at it. Then there is additional labor and parts.
