Please help if possible, total newby -
I am having an issue where the pop up bumper (under whiplash) is not responding when the ball hits it. It simply is dead other than the light working as it should. I did a switch test and I noticed that when I tapped the white retainer under the steel ring on the playfield that it did not respond as it should. I called Stern and they told me to press the copper or silver contacts closer together on the bottom the playfield. I tried that and no luck, I noticed that the sound does not come as if there is contact at all during the switch test as it did with the others, as I literally pressed them together. The coil test was okay and so was the lamp test.
Does anyone have an idea of what this might be?
Thanks ahead of time.
