Hello Pinsiders.
All the #47 playfield and head lights in my Lost World that blink or go off and on when hitting targets seem to be getting dimmer. Both when sober and after a few. The GI lights are all good and bright. I have reseated all the ribbon cables to no avail. At some time, the lamp board had been replaced with a Stern LDA-100. Any thought(s) where I should start?
