Sign me up! I have a High speed, Diner, and now a Taxi. I posted this in the Taxi club but probably should have put this here.

The bottom row of the main display is totally blank. Top row works fine, the separate 7 digit display works fine. I have a Diner with a led replacement display so I swapped it into Taxi but I had nowhere to plug the 7 digit in.

Now I get info on all 4 player sections. Top row (1 and 2) look fine as before. Bottom row player 3 looks mostly fine but missing the occasional segment. Player 4, the display is working but all the inner extra segments are lit all the time make it impossible to see the main segments displaying words.

Swapped the display back into Diner and it looks normal again. Any idea how to figure out what is happening?

One other question, how do I get the Taxi topper to light during test? It does not seem to operate during solenoid test mode.
