Led light is on, but nothing else works.

Led light burns, but nothing else.

How can I check if a snes is actually broken?

I recently bought a pretty cheep snes, it was missing several kabels. I still had some kabels, and tried hooking it up. Following a guid, because I had not done so before.

But the it wouldn't turn on. It does have a working led-light, so I know it has power.

All the voltages check out as well so I couldn't have killed the snes.

I would like to check if there is something wrong with either the way I tried to set it up, or the kabels, or even the tv.
