TROUBLESHOOTING
Hopefully you’ll never need this section! If you have a problem with your kit,
don’t panic. A sensible, logical approach and a clear head will usually point
you to your trouble spot. The first thing to do is to look over the board again
and check to be sure that:
•
All parts have been installed unless you were instructed otherwise.
•
All parts that have a polarity such as ICs, diodes, voltage regulators, and
electrolytic capacitors are placed correctly. Check the silkscreen and/or
Parts Layout Diagram if you’re unsure.
•
Check your solder joints for cold or intermittent connections as well as
solder bridges . . .unintended connections between components. Touch
up any less than perfect solder joints and check any questionable
connections.
If you still have a problem after visual inspection you’ll have to do some
troubleshooting to find it. The second most common error we see (after poor
solder connections) is misplaced components. It’s especially easy to goof up
on resistors with red and orange color bands; check those first. Taking the
circuit in sections can help a lot, for instance, if your kit will not power up at all
check the DC input jack and voltage regulators along with their capacitors. If
you get no sound from the speaker try connecting an external speaker or pair
of headphones; this will determine if your problem is simply the speaker or if
you need to check over the entire audio section. Figure out what works and
what doesn’t and go from there.
If all else fails, check the inside back cover of this manual for instructions on
how to send the kit in for repair. Hopefully you’ll never get to that point but it’s
nice to know that there’s someone out there to help you if you do.
