long story short, i switched it on yesterday and nothing at all. no LED no nothing. i took it apart and didnt see anything out of place with a quick glance, aside a minor "spot" in the corner of S-SMP chip, which might indicate a burnt chip but doesnt look big enough to give a definitive answer whether it's burnt or not. cant really say much about it but i cant rule out the possibility that an incorrect power supply was used on it, which could have fried something. any ideas where to start checking things up ? does the SNES have a fuse that fries up in cases of incorrect power supplies ? also, does a fried S-SMP cause it to completely die ? (not even power LED lights up) any help would be nice, i'd really rather not buy a new one just yet oh, and the model is the old kind 2-chip euro launch unit (donkey kong country bundle)
I doubt you would have used a wrong AC adapter on it, the connector it uses is very uncommon, if not unique. Edit: At least on the N.America model.
the power plug in euro snes is pretty common actually. or dunno about common but atleast i have a pile of power supplies that fit in just fine. either way, it's not certain that one was even used on it, but i cant rule it out since i did test it with several ones last time i used the thing. I left it out unused for a while after that so dont remember too well but it's possible i suppose. i'll check out the fuse from the machine as soon as i get time to do so, hoping it's just that instead of something more severe
From what I understand the European SNES units are quite hardy and don't mind either AC-AC or AC-DC (either polarity) thanks to the rectifier. US ones are not so lucky apparently. Feel free to correct me if I'm wrong, I've only use AC-DC adapters (with either -ve or +ve centre polarity) so far. I don't think I have any AC-AC adapters. Got any pictures of the SMP chip? Here's one of mine for what it should look like.
dont have one but i'll take one when i take it apart while i check the fuse. as soon as i find a diagram showing where it is Edit: well that was quikly solved, it's the fuse allright. gonna get a spare tomorrow and get back to Chrono Trigger in no time :3 thanks all~ <3
yup <3 it's all alive again, found a set of old glass tube fuses and decided it's easier to just solder in a mount and use a replaceable fuse incase of future mishaps It's running as good as new again. also hooded it up to a 28" CRT with RGB and overkill 5.1 audio gear for the first time now. It's purrrrrfect :3
Keep in mind that: Inserting a cartridge backwards is enough to blow the fuse. Inserting a controller with shorted out cable is enough to blow the fuse. Anything that causes it to draw more current than it's supposed to will cause the fuse to quit.
i wonder if the LED i changed does it used a blue superbright on it, it's been working fine for a good while though, but it's indeed way more powerhungry than the standard red one also, how do you insert a cartridge backwards ? O.O
Hahaha, easy my friend! Remove the casing on the cart and face it forwards (microchips facing front) and you've exploded it! It's an odd sensation having a bare cart in there facing the rear of the console. It doesn't feel quite right...! If you keep the cases on the carts you shouldn't have any problems though! :loyal:
Anyone familiar with FAMICOM carts would know that Nintendo aways make their cartridges with the chips facing the TV set/rear of ther system instead of facing the front, like SEGA does. The NES was a slightly different animal, you see.
How... backward? :biggrin-new: Interesting to know though! I think we've all learnt something here today! :topsy_turvy:
It happened to me once, by accident, when I was working on a bare motherboard. Without the console case nothing prevents you from inserting a cart backward. Made the mistake only once, Im not sure but i think it made funny colors on the screen when I powered the board. I quickly noticed my mistake and fortunately the system did not seem to suffer from it.
