Troubleshooting
Not all DIY builds work first time. The vast majority of build issues are down to soldering
inconsistencies. This is far more likely than a bad IC, for example. The first step of successful
troubleshooting should always be to reflow all soldering to eliminate any dry joints (bad
connections) or solder bridges (short circuits). This is also an opportunity to closely inspect
your work
–
you might find some unsoldered pads, or an IC not inserted into its socket, for
example. Next steps are to double check all resistor values are correct, and to check
polarities of all diodes, transistors, ICs and electrolytic capacitors. This is not an exhaustive
troubleshooting guide, but should address 95% of build issues.
