I have a #WPT and here is the situation:
1. I am missing an entire lamp column (03 - IC-U15)
2. A lamp socket was broken and dangling and I think very likely shorted (now replaced)
3. When I measure the pin on the board for the broken column it measures different than the other pins when in "All Lamp" test mode (So I am pretty confident it is on the board) It has voltage but it is maybe 25% of the others (it fluctuates so it is hard to pin down exactly)
4. I had previously measured the transistor and it measured weird so I replaced it (it now seems to be the same)
5. I had previously measured the small 47ohm resistor and it measured 0 ohm so I replaced it (it now seems to be the same)
I reinstalled it and it still doesn't work. I remeasured the voltage on the pin and it is still much less than the others (however it still has some voltage). I traced all the traces in the circuit and they all connect. The diode seems to measure right, the transistor matches the others (however I am not 100% sure how to properly measure this, I am using diode on my multimeter and just checking it matches the others) and the resistors seem to match. I am kind of stumped as to what to check next (or recheck) and would love some help. Here is the circuit. I don't see any obvious damage and the transistor is getting 18v.
