I have a US model NTSC SNES . I live in Malta (Europe) not USA , but i am using a correct voltage adapter and my TV has NTSC support .
Basicly here is the problem:
It worked fine for a couple of days with abs no problems at all .
Now it doesn't work at all

I switch it on and the power light comes on for a second and the screen shows like the snes is powering up ... But then it goes dead .
I've checked all the connections and they are fine , and i tried using different POWER ADAPTERS and different outlets .
I've also checked the internal fuse in the SNES which is fine .
Any ideas ?
