Hi there I recently replaced the flyback transformer on an Star Wars Cockpit cabinet from cinelabs. But when I was going through the process I noticed that one of the transistors (VR2) was damaged and you could easily see inside the component so it looks like it needs replacing. I'm just trying to figure out which transistor they are to replace and if they are simply plug and play. The pcb is the green version for a Amplifone monitor. I have looked at the schematic in the cinelabs manual and I think these are the right parts but could someone confirm they are right pretty please.

VR2 - 7924 - http://www.cricklewoodelectronics.c...WBPaukghoNwZazpyB9tzbJvLxoHKU1MptKxoCbenw_wcB

VR1 - 7824 -

Those are the correct voltage regulators.
 
If one of those are blown apart then you probably have other issues too.

Agreed. Could also have been that your original high voltage transformer blew the regulator but be sure to check other parts. That BU406D on the heat sink by itself for instance.
