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?
Lamp board (resized).jpgWell I installed a new lamp driver, Tested outputs on my MPU, Voltage Regulator and the Rectifire boards. Everything test ok but every lamp that flashes in test mode are dim and getting only 2 VDC to all those bulbs. both in the playfield and the backbox. Machine worked great for years. Any other place I should test?
