5.12.2.7 One digit is out on one of the displays

Changed Q3 and Q9 with no success. They tested perfect so i didnt thing that was it. Anything else I should check. Nothing burnt, and all solder is reflowed as there was cold joints on header.
Quoted from jj44114:Check the 100k resistor for that digit. They often fail.
These are in the row close to the glass.
When you compare the resistance on all the 100k reaistors on the board, it will be very noticable. Resistance goes higher as the resistor fail.
Quoted from Barakawins1:You have to pull from circuit and test
Thought that was for a diode, not resistor?
The 100k resistors can be tested in circuit. Any where between 80k and 130k is fine. They fail by burning and going open or having very high resistance.
