I think F2 should be 3/4 amp slow blow.

Disconnect J3 on the rectifier board - does the fuse blow? If yes - check the diodes.

If no - disconnect pin 8 on the J3 connector on the driver board. If the fuse blows you have a problem in the high voltage section.

If no - you have a short in one of the displays.
