Re: Lexicon front panel display

Bad solder joint.
Backlights for displays often have a little circuit to generate high 
for them. This circuit cutting in and out could certainly put noise onto 
audio signal path.
Alternatively the fault could be in the power supply.
Either way, take it to a good tech.
