I have a display (player 4 in the pics) on my EBD with the same segment (f) out on all the digits. I replaced Q18 per pinwiki which didn't fix it, so I also replaced the decoder IC and still no change. Any suggestions on what to look at next?
20210502_184851 (resized).jpg20210503_135736 (resized).jpgQuoted from pinwiz_pa:Check connections between U1 pin 15 and Q18. Also check R23, R24, and R28 to make sure none have opened up. If you have the schematics go thru the whole circuit to make sure there isn't a broken trace somewhere. Hope this helps.
There is continuity between U1 and Q18, and all these resistors test fine.
Quoted from BigAl56:Probably a bad resistor or solder connection to the panel. Check the resistors in the segment drive with a meter and resolder the glass panel connections.
I reflowed the solder on the glass connections with no change either.
Is there anything else I should be looking at on this? If I swap displays it works fine, so I know the issue is on the display itself somewhere...
Quoted from FatPanda:I think you will have to replace all of the displays, if I'm not mistaken. Not just the one display.
I don't think that is the case with these based on what all I have read about them (https://pinside.com/pinball/forum/topic/wolffpac-6-digit-display-kit-review), but I have never used one before, so hopefully it works out.
