Subject: Poly 800 mk1 top segment of LED not lit

From: "tombarndt" <tombarndt@...>

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?
