If the Input LED is flickering from the noise you are hearing, then the
volume of this noise is far higher than the typical noise floor of an
echoplex. Sounds like you have developed some sort of hardware problem in
the analog input or mix sections. Something might be grounding to the
chassis somehow when it shouldn't, or maybe a broken solder joint, dirty
pot, or something. Probably a decent electronics tech or repair shop could
fix such things for you. Cleaning pots you can do yourself, you should be
able to get the stuff for that at an electronics parts shop. You might as
well have it on hand, because anyone using electronic music gear will need
it eventually.
