Where can I get a replacement clear backglass for Monopoly I tried Marco but they say they don’t carry it

Hello. Need some help here. My bank letters don’t register when the ball hits the bank door. I did a check of the bank opto in the service menu. Nothing registered. I see the top lights are lit but the bottom is not. Do I need a new opto board?

Thanks. Jiggled the wires and sure enough the top wiring was indeed loose. Will have to look closer at it tomorrow. But thanks for giving me the tip that led to a short term fix for me !!!

Sure enough the top wire connection was loose and had some corrosion. Once cleaned and refastened it works again.
