No Active Start – Drive/Display Test
Condition: Voltage across drive board connector CN1 pin 1 and IC U3 (40106) pin 4 should vary
from 0~5VDC.
Response: If voltage does not vary, replace the drive board. Possible bad components: IC U3(40106)
or U2(LM339) (see below). If voltage varies, the drive board is good. Perform a continuity test on the
main data cable. If it is good, replace the display. If it is bad, replace the data cable.
