Ice Tube Clock has no Display
I am at the installing the max6921 chip stage of putting together my Ice tube clock purchased from Adafruit and have hit a snag. I have just installed the Max6921 chip and plugged in the VFD and I have no display. Prior to installing the chip I had the following voltages. Voltage regulator input 8.85Vdc, output 4.97Vdc. 56.6Vdc at striped end of D3. The three leads on transistor Q3 are 4.67Vdc for the two outside leads and 0.3Vdc on the center lead. After installing the Max6921 chip with dot toward buzer I got the following voltages: Voltage regulator input 8.13Vdc, output 4.97Vdc. 8.40Vdc at striped end of D3 and transistor Q3 had 0.47Vdc on lead nearest outside edge of circuit board, 0.003Vdc on center lead and 4.60Vdc on inside most lead. Curved side of transistor Q3 is toward the striped end of D5. When I plug in the VFD nothing lights up. I am only seeing very low voltages on the VFD wires (around 0.1Vdc). I put the Max6921 chip in upside down initially and powered it, realized my mistake and de-energized and removedand re-installed correctly. I'm afraid that I have damaged it. I would be willing to pay for a replacement.
