So after finding the melted LOPT on the APB monitor, I have taken a donor LOPT off another K7000 chassis ready to fit on this chassis.
As usual, when I have any monitor on the bench that still has its original capacitors in place, I replace every single one including the B+ filter and the non-polar video caps.
After that is done, I need to check the board over for faults. The fuse has vaporised, which usually means there is a dead short somewhere, as the LOPT melted, I will asume it is probably the HOT that has shorted with it, but it could also be the main regulator
