is it just one "8" display section or is it the entire group of "88 88 88" displays that are missing the top segment?
Hard to tell from your description and very pertinent information to help in the diagnosis.

> I've been searching the forum for this issue and haven't found it yet, the issue is the top segment/line of the LED display isn't lit. Everything else work great. I checked voltages feeding the displayboard and pin 5,and 6 are at around 2.8-3V and every other pin is showing between 5 and 6V. No obvious break in the yellow 14 wire cable and no obvious damaged traces. Wondering if anyone else has had this issue and if there are further tests to narrow the search. Possibly IC30 or IC31?
