View Full Version : SNES on my HDTV

So after tinkering with my old SNES to no avail, I purchased an SNES 2 (the smaller one) at a flea market. I tested it on a small LCD TV in our kitchen (It's not a high def) and it fired right up and I had no issues. But when I hook it up to my Samsung CRT HDTV, nothing happens, not even a black screen. Doesn't flicker at all either, but if I take it out to the kitchen again, no issues. I tried plugging it into different inputs, tried plugging the power supply into different outlets, nothing worked.

However, my original NES, Sega Genesis, TurboGrafx, and PS2 all work in the same inputs.

Any ideas?

There shouldn't be any reason why it wouldn't accept the signal. My first guess would be bad inputs on your tv. See if your TV has another set of composite inputs (maybe on the side) and try it there. If not, hook up some other device using the same ports on the tv and see if that works. If it also doesn't, your TV is obviously the problem.

If you are hooking it up through the rf adapter go buy or steal a set of composite cables from your N64 or Gamecube and hook it up that way. The RF adapter should work just fine too though, just double check all your settings and be sure that your SNES is set to output on the same channel you expect it to. Try the other channel as well just to be sure. (I'm only assuming SNES 2 has the same switch as the original. I don't have a SNES 2... I do want one though)

the snes two does not have a channel switch or rf port, it was removed for mobo consolidation and we were left with a pretty AV port only :D

Try moving the cable around in the back of the snes, my ps1 bothers alot so it has to be taped to stay put. Make sure your on the "channel" that accepts composite.

btw what was wrong with the old one?

Well, I finally got it to work.

Apparently it doesn't like any of the three power strips I was plugging it into, but I plugged it into an empty recepticle on the back back of my computers UPS and it worked fine....

Not sure why all THREE of my power strips (not the same brand either) would cause it to not work. I tried unplugging everything else in them but got the same results. No other system or device has any issues with any of my power strips.

I tried using the standard AV cables, N64/GC AV cables, RF switch (it's an original) but all I get is a black screen (even if I try to plug it into the small TV in the kitchen, and used both power supplys I had). I cleaned out the cartridge slot, and cleaned up all my games like new, but still got nothing but a black screen. I took it apart to see if anything is fried, nothing looks bad, but that doesn't mean anything. Lack of a tester leaves me without a way to properly check pots and caps (and I'm not sure if there's any fuses on the board, i don't know much about the SNES board). I really need to get myself an electrical tester so I can start digging around in there.

there is indeed a fuse on the board, near the back left where the switch plugs into. The black thing that bridges the gap there. Thats the fuse, does the power lite come on? I know that if you work on the snes without discharging it first it will destroy it. Your power port could also be loose aswell on both.

It does light up, and my SNES hadn't been used in about 12 years when I opened it up, so there certainly was no charge in it. No static either, I discharged myself before I took it apart.

there still couldve been charge in the caps, alot of components hold a charge for a very long time. Oh well youve got one working so thats good.

If it means anything, I did turn the power on with it unplugged before I opened it to discharge anything that could have been there (I always do this no matter what, call me paranoid)

But yeah, at least I have one that's working, been playing Final Fantasy III finally. Although I wish I could have my original working, just for the sake of memories. :D

Most likely a ground loop problem. Were those 3 plugs from the same wall socket that the TV used?

Two were from one socket, the third was on the other side of the room from a different socket.
