Hi!

I've got a SNES that recently decided to stop working. I've taken it apart and can't figure out what's wrong. I've followed the usual troubleshooting advice (tests below were done with my multimeter):

1) Verified the AC adapter is working
2) Replaced the fuse and tested it to make sure it is working
3) Verified the power switch works
4) Flipped the board over and checked the voltage coming in at the solder points where the power is connected
5) Removed the voltage regulator, hooked it up to a 9v battery and made sure it is working, (output is 5v)

All the above components look like they are working, yet it doesn't turn on. When I plug it in I see power is going to the board from the adapter, but when I read the voltage at the voltage regulator input it reads 0. To test this I plug in the board, turn it on and then touch the input and ground on the voltage regulator, and it reads 0

Any ideas on what to try next?

Thanks in advance,
