display issues with a SNES

[madmax2069]

Hello everyone

 

I have a SNES that displays two scrolling horizontal green lines. The TV I have it connected to is a Sony Trinitron, connection method is by using the multi out.

 

I haven't tried another TV but I have never had any issues with any other consoles hooked up to this set.

 

I do however have a 3rd party power brick that works on nes, SNES, Genesis rated at DC9v-850mA.

 

Any thoughts

 

I will try to post pictures of it and or video.

The power supply can most definitely cause this problem. I would try to get an official or I have these 3 in 1 aftermarket ones that work great for nes and snes but give those lines in the genesis and cause a humming in the genesis.

 

Here is the link for them but don't buy them for genesis systems even though they say they work.

That was the seller I purchased from, you don't need to but that many. It was just the 1st link I found.

That's the one I have

Well you only have 4 choices really. It's tv, power, rf, or system. I'd start narrowing it down. I would say it's most likely power or tv myself. I'd hook-up anothem system and see what happens and move on from there.

I can rule out the TV due to the simple fact it works fine for my n64, gamecube, ps3, 360, Genesis, PSP, apple iigs.

 

I can rule out the AV cable due to the fact its the same cable I use for my n64 and gamecube. I don't use RF.

 

This only leaves the system or the power supply. Being that I do not have a official power supply nor another SNES I can't test those at this minute. I can however take it to the place where I bought the 3rd party PSU and have them test it out.

 

How would a power supply produce this artifact on the TV? Dirty power, not producing enough, producing too much

Can you show me a pic of that power supply label? Not the box, but the actual one you have.

 

Is this a normal snes or is it a mini or aftermarket?

Yea that looks identical to the ones I got. I think there are a few diff. versions. Take it back and have them test it for you. Take your system as well.

Sorry for taking so long to update this post.

 

I had the PSU tested and the Guy testing it (he fixes consoles for his store to sell) said its doing what it should be outputting, and nothing odd. This is also the same Guy I bought it from. He also hooked it up to another system and let it play for a half an hour and no green lines.

 

Its definitely not the TV as I had to replace my Sony trinitron (which was what I was using at the time) with a HDTV.

 

Its definitely not the composite cables, tested on N64 and gamecube.

 

The only outcome is the system itself.

 

Here is a video of said issue

 

Could bad caps be the cause of this issue, or overhearing, Or something else entirely. When the system is first powered on I do not see these lines, after about 5-10 minutes they start to appear (small and barely noticeable), they get worse with time. They also only are seen when graphics are being displayed, when the screen is blank you don't see them (the more graphics being displayed the worse they are). The above video is after about 2 hours of play time.

I googled and found an Amazon reviewer who had the same problem that was apparently caused by a bad adapter.

Quote from Amazon reviewer:

 

After seeing the image of this product, I thought this was the official SNS-002 charger for a Super Nintendo. When it arrived however, I found out it was actually a Tomee 3-in-1 AC Adapter for SNES/NES/Genesis. I was initially fine with this, as it wasn't very expensive. After plugging in the Super Nintendo I had just bought that came without an AC adapter however, I noticed big green lines scrolling down the screen. After researching it, thinking it was the system, I found out that was caused by a power supply that doesn't provide the right power. I went to pull the adapter out of the outlet to check it, and one of the prongs broke off and stuck in the outlet. This was the first time I went to remove the adapter, and I did not use any excessive force. Obviously it no longer worked at all after that. After looking at it as I was trying to do when I pulled it out in the first place, I saw that the adapter not only doesn't match the image the seller provides, it doesn't even match the packaging! The adapter shown right on the packaging says it is 9V 850mA, while the product inside says 10V 1000mA. Overall this product is a total waste of money and the seller is trying to completely deceive their customers. Do not buy this product, it's not worth even the couple dollars it costs.

Those PSUs are absolute crap, toss it and get an actual SNES PSU.

[madmax2069]

WTF, so is it just dirty power or too much or not enough. Dude tested it and said it put out what its label said, hooked it up to another SNES and didn't display the lines, unless he pulled a quick one on me.

It can't be "too much". Your SNES might be a bit more aging or having been used more, and need a bit more power than 850mA.

Get a PSU with 1000Ma/1A output (or more, it doesn't matter) and you should be fine.

 

Those kind of PSU must be tested with something (like the SNES) draining a lot of power. If tested with just a measuring device or something like a lightbulb, you may not see that when asked to deliver those 850Ma, the voltage drop down.

it's definitely the plug.

just bought one of those 3-in-one plugs (brand name is "Orbital Accessories")

works, as in it turns on the system...

just it gives me green lines that scroll up/down the screen.

 

I can't deal with that.

I'm going to try to return it as soon as I can get back over there (an hour drive for me from where i bought it, sadly)

 

 

p.s., the issue is NOT my system, i have an official plug here as well, i just needed an extra one for my other system.

the plug is the problem. nothing else.

 

this product is a p.o.s.

(sorry for double post-- but)

• 
  i think i found a temporary solution
  
• 
   
  i may keep it after all
  
• 
   
  i swapped out the official SNES plug i had for my virtual boy and will use that for what i need because this generic plug seems to work fine with my virtual boy
  
• 
   
  i just hope it wont kill my system or anything. it concerns me
