I'm pretty sure my N64 is dead. im inputing the right voltage in the right slots, I checked all 11 fuses on the console. all that happens when I turn it on is the power LED comes on and the video and audio on the TV its attached to spike, that is, the screen flashes once and the speakers click... then nothing. is there anything i havent tried?
Also try this: remove the game and turn it on for 5 seconds (then turn it off). Put the game back in and try again. If it works, you probably removed the expansion/jumper pak recently.
