Auto fire?

[0078265317]

The 7800 I got off ebay arrived today just couple hours ago. Still got to find an ac adapter. Anyhow all is good and looks in good shape. A little dust or something rattling inside but nothing major after I opened it up. All looks decent.

Anhow it came with 2 controllers. I don't have a ac adapter to test. I will keep an eye out. So I used the my JR just to test. First pic. Controller on the right works fine. But the one on the left keeps auto firing. Was playing space invaders and they move left and right and only fire when I press orange buttons on the sides. But the controller on the left fires all the time when plugged in even when I am not pressing the side buttons. Its not a bad jr because it is only that controller. The other one is OK. I actually like it so I can move left and right with one hand and can hold the controller with the other had. And I don't have to press the buttons. It just rapid fires and kills the invaders. But I know that's not normal. And idea why its doing that?

I just got an awesome deal. So we will see in a few days. Will let you know if its working. I hope this is the right part.

It's possible one of the little dome switches in the controller is collapsed in. Open it up, and if eother one of the buttons is collapsed, just try pressing around the edge of it with a pen, and it should pop back up.

Exactly what happened thanks. Even the slightest pressure on the right side as looking when opened upside down caused firing. Bending the metal cone thing back and re assembling it caused not as much pressure and only fires when I press now. So all is good now thanks.
