Working on a powerbook 2400c I thought it had a bad backlight so I replace the bulb but still no backlight bought a tester for the bulb and confirm it's working so I supect it's the inverter board so I figured I ask a few questions. in the attach picture does anyone know if F1 is a fuse? It look like it marked 1.25A ? 73 I checked and it doesn't have continuity. Second question second picture on transformer should I have conitunity between the two right soldered connection. lastly open to any suggestion on things to check/testing. Thanks in advance.
