Hp FN747AA Computer Monitor

[Fisher77]

My main computer monitor died. The monitor did alot of jumping around(interference/jitter) is the best way to explain it, and then quit. When I turn it on now the backlight just faintly flashes on and off repeatedly. I tried it on a different PC with the same results. I removed all the covers and reconnected it to a computer and I can hear a pulsating buzzing noise coming from the power supply. The power on led flashes on and off along with the noise. All voltages on CN902 are good except there is no voltage on DIM. I checked what I know how to check. Was hoping I could some help diagnosing this, and learn something new along the way.
