When all the above did not bring you any closer to a solution,
start thinking of a defective part or parts. Semiconductors like
transistors, FET’s, IC’s and processors, although very reliable
do not support abuse. You can send us suspect
semiconductors for inspection and eventual exchange but keep
in mind. Our experienced technicians can tell the difference
between a defective and a fried transistor, and in several cases
a stamp is much more expensive than a replacement
semiconductor bought at the local store.
Any Velleman-Kit if defective will be repaired or replaced at our
option within 30 days of purchase.
Simply return it to the place of purchase with proof of purchase.
