How to Troubleshoot
During Soldering/Assembly
- Follow the soldering tutorial video or Assembly Instruction closely.
- Do NOT skip steps.
- Test the voltages as directed. If they are incorrect, stop and figure out the problem. Do not proceed until the voltages test okay.
STEP-BY-STEP TROUBLESHOOTING
If it's not working after assembly:- Check all IC's to make sure 1) they are at the correct location; 2) they are in correct direction
- Check diodes to make sure their polarity is correct.
Measure TP1 and TP2
- TP1 should be around 1.3V, and TP2 should be around 26V. If not, something is wrong with your power supply portion.
