Im looking for some tips on diagnosing a bad CRT. It is an NEC MultiSync FE1250 that is losing picture (as if I turned it off) repeatedly. As this progressed it takes longer and longer for the image to come back on and its symptoms appear more frequently. If I physically turn off the monitor and turn it back on the image with come back momentarily before again going blank. My searching seems to point to a bad flyback transformer but Im hoping to get some advice from someone more experienced.
