I am getting no picture
the monitor had 2 bad resistors R436 & R439, Replaced them, then the flyback shorted through the housing on to the metal shield of the flyback. Replaced the flyback still no picture.
I get static on the tube, checked the brightness (nothing)
Can someone tell me what to try next?
