Hey guys,
I don't mean to highjack the thread, but I have a similar problem on a EATPM. Except it's the opposite in that the upper left "hash" on the left screen will not illuminate.
For example, a "9" looks like a backwards "F" and an "8" looks like a backwards "6".
Quoted from dewdude82:You said you had a Police Force; if you swap displays and the Police Force display is fine in Taxi; then you know your problem is going to be one of those two chips (or the ribbon).
I also have Taxi and Police Force and I actually did swap the displays (sorry Police Force, Taxi gets priority haha) so this test will definitely work for you. Yeah just go ahead and do it. They aren't as delicate as you think, but obviously use care when swapping!
