Further update... and I wish it was good

.
Obtained a step-down transformer rated to 100W.
First time I turned on the monitor, the screen was filled with a white, bright picture. That displayed for about 15 seconds and then the 3 amp fuse blew. Now, everytime I turn on the monitor, it blows the 3 amp fuse.
I'm just about ready to take it into a eletronics repair place and have them look over it as I'm itching to get the cabinet going and play some classics! Arrghh!
Would anyone please have any further ideas/help? It would be really appreciated!
