Question about Sega Genesis Console

1 Answer

Line across top of screen

I just got a practically new Sega Genesis off Ebay and it seems to go through phases. It displays a thin horizontal line across the top of the screen. This line isn't there all the time but it always gradually appears over time when I play a game, usually getting thicker. When I switch to another game it's still there. Sometimes it's already there when I first turn on the system after not playing it for a while. I don't know if this is a normal thing for a first generation Sega Genesis (1991 model that comes with Sonic 1) but it gets me wondering. Most people wouldn't care about it but I just would like to know if it's normal. I used to have a Sega Genesis years ago and I played it on rounded cornered and sided TVs that would hide the line if the line was normal, but now with a strait-cornered TV I can see it. Could you tell me anything about this line, if it's normal or not for a practically new (Very new really) Sega Genesis? Thank you.

    This is a United States Sega Genesis.

    Another comment about the line which would better clarify it is that the line is a color that changes as you go to different areas of a game. The color changes when the primary background color changes.

    Forget about this problem. Putting this problem on this site was a waste of time. I'm getting adjusted to the line and it isn't really bothering me anymore. I don't need a solution anymore. I'm sure it's normal for this model and version of this Sega Genesis. Sorry. No need for anyone to post a solution for this one.

    Hello. Feel free to talk about this line.

    Is there a way to eliminate the line? Is this common on strait-cornered TVs or most TVs including the ones back in Sega Genesis Days? Actually I'm still interested in this subject. Just wondering.

    The last comment was made after the solution, so it would be nice for it to be resolved. I am still interested in this line subject, and really wasn't entirely not bothered by it.

The line is actually part of an unseen border.

Bought a Sega Genesis on ebay. It displays the games correctly but will not respond to the controller. The controller has been tested to work with another system. What could be causing this?

Its the controller ports inside of the system that controlls the controllers to function is broken or loose then and needs to be resoldered. I had a problem with my sega after i resoldered the 2nd controller port it worked again then.

I have an old sega genesis and got new plugs to plug it into my 42'' HDMI Vizio. all the plugs are in and the light is on but the screen stays blank. I have tried blowing on the game and got the...

Did you say HDMI? I don't think there are HDMI plugs for Sega Genesis. You can plug in your Sega via composite video through RCA cables (yellow, red white) or via RF signal through coaxial cable. Check your TV's specs to make sure it can display standard definition content via composite or via RF.

You can double check to make sure your Sega Genesis is working properly by plugging it into an old-fashioned CRT (fat tube) television set.

I recently plugged in my Sega Genesis (MK-1601) console and purchased A/V cords to hook to my tv. When I turn the power on (the red light goes on), I usually just get a flash across the screen and then a...

This is pretty common. The games just need a good Q-Tip cleaning, and then the weird clean pencil-eraser rubbing.
Get out a Q-Tip, and rub it inside the game, on the copper part (The part you stick down into the system.). Keep doing this with new Q-Tips if the old ones get soiled with black stuff. After the new Q-Tip comes out white, it should work.
Sometimes, that isn't enough. Use some Windex or any other rubbing alcohol, dip it onto a Q-Tip, and rub it onto the copper part. Then, use a dry Q-Tip to dry it off, and let it sit out of it's case and out of the system for about 20 minutes so that the alcohol dries.
If that doesn't work, use a pencil with a clean pink eraser at the tip. Rub it inside the game, and use a Q-Tip to get all of the eraser shavings out. This breaks the electro-static cling/friction made when the game is being read by the system.
And if none of that works, go on Amazon or Ebay or to the store Slackers and get new video and AC wires for the Genesis. Sometimes that's all it needs!
I really hope this helps!

How do i set up my sega genesis

There should be regular av cables and wall adapter for it. Mine came with the wrong cords and that might of happened to you. So if you don't know the av cables go in the back of the tv and plug's in the back of the sega. and the wall adapter goes in the wall. If you don't have the cords than get them off line. Type in:

cut and paste it online and you can get them.

Sega genesis isnt working...

Have you cleaned the Sega? What I mean is where the casset game goes. Push down the little flap, and there should be a little strip with contacts on the inside. Just clean it with a cotton swab and alcohol. And also, clean all your games also the same way.

Hope this helps.
