No output appears from the function generator when the unit is turned on.
The most likely reason is damage to the output amplifier. To verify that this
is the problem, turn on the unit, increase the amplitude, and check for an
output signal at U4 pin1. If the signal is missing, then please contact
customer service [(800)-772-8700 x 78] to return the unit, referencing this
If the signal is present, then the output circuit needs to be replaced,
which consists of the following chips: U4 (430-095), Q1 (420-002),
and Q2 (420-003).
