Are you POSITIVE the fuse is good? Do you have a multimeter? Don't chuck the old HOT yet, it may be fine.
With a multimeter, check the resistance on that large white resistor on the back right corner that sticks straight up in the air. If that's good (the value is printed on the side of it), check all the diodes in that area. See if any of them are shorted out.
Then check the diode right beside where the yoke plugs in.
Then check the 1 or two large caps underneath the metal cover that the HOT bolts to. See if they're shorted from one side of the cap to the other, and then again if there's another one next to it.
Then check and see if the middle leg of the hot is shorted to the metal plate the HOT is mounted to.
When the monitor first comes on, do you hear it snap crackle and pop?
Let us know, we can get this sucker going!
