Can A Twin Famicom Just Stop working?

[okame]

I have an old PS2 box, and I put my Twin Famicom in it to see if it would fit if I ever need a box for moving the system. I plugged it back in, then hooked it back up to my TV, and...nothing. I tried the A/V plugs, and they work on my Retron 3. I tried flipping it to the FDS setting, and no title screen. I tired 2 different carts, and neither works. I unplugged everything, checked the AC wire and and the voltage adapter I bought. Everything seems to be in the exact same condition as it was 2 days ago, and I was playing Dr. Mario on it just fine. I even tried to plud the adapter directly into my power bar. My TV was set to Video 2, like always, the same one I use for my Retron 3, but it still says that there's no signal. What's wrong? Is it possible for a Twin to just stop working completely? It IS over 30 years old, after all! Help! I got a copy of Doki Doki Panic, and I can't play it unless my Twin is working, and I'm NOT buying another FDS system! I already bought one to swap out the drive on my Twin!

Turn out I need a new power adapter. The wire finally split on me! Like I keep say, the system is 3o years old! I'm 36, and some of my parts stopped working properly in my TWENTIES!
