Where can I find schematics, or service manual for NEC Multisync E700
monitor?

Yesterday, only the top half of the image showed with kind of a bright
line across the middle [streaked to make it], before I could do
anything, the screen went black and even the LED power ON/OFF
indicator is not on.

Is there a replaceable fuse? or such

Or is it more likely to be the vertical deflection driver died?
