As an EE, I can confirm that every part is important and has a function,
it would cost more money to put in extra random parts. ;)
The mostly likely problem, is that the small caps are starting to fail,
and they are leaking, or one has failed 100% and is shorted...
An Ideal cap blocks all DC current, so with it in series with a resistor,
you would have no current flow. AC current would need to be a very high
frequency to pass.
