Pet64 DOA

I just got myself a PET64 from Yahoo Auction Japan. Quite a rare  
machine I hear, so I'm not sure how one ended up in Japan. I got if  
for a decent price as I don't think the Japanese knew exactly what it  

Anyway, It arrived the other day, after a quick internal inspection, I  
powered it on. I can hear the transformer buzzing(!), but no action at  
all on the screen at all, and it doesn't seem like the chips are  
getting warm at all Maybe need to leave it on a little longer to make  
sure, but I didn't want to do that incase bad voltages kill anything  

There are 4 wires leading from the small PCB which is attached to the  
transformer to the C64 motherboard, and I have measured the voltage  
from the black wire (GND?) to the 3 others. Here are the reading i get:

White: - 100mv
White - 100mv
Black (I'm guessing this is ground)
Red - 4.98v

That's as far as I have gotten. Next I will remove the motherboard and  
see where exactly these 4 wires go.
Anyway, I was just wondering if anyone had any insights or thoughts.
