I'm working on a Taxi I just got. I'm down to the smaller stuff after putting the topside parts back on. The current issue is the display. The top row works great, the bottom row isn't displaying anything. Totally dark. Is there any way to test if it works at all? Reading through the pinwiki, all it seems to talk about is if everything is affected by a power supply issue. To me it seems that power is going in fine, but might only be going to the top display.
