I have a GQ5200 rework station.
temperature display on the hot Air display has a bad (non-operating segment.
The right most digit in the 3941 7 segment 4 digit display has a non-operating segment.
.....this is a 12 pin multiplexed display....and all the other digits and segments work correctly.
SO I am assuming it's just a bad segment in the first digit.
it's listed as LED 3941 in the schematic.
Can anyone point me to a replacement source for the display?
...or even a direct drop in substitution/replacement for the 3941.
I have been unable to find it anywhere....
THX in advance....
