I have got a Digitech Whammy DT that has decided to go mute every time I press the Whammy or Droptune buttons.

I have done a calibration and this has not worked. When I switched it from true bypass to DSP no signal was getting through the pedal.

Any advice on what I can do would be much appreciated.
How are you powering it? Do any of the lights happen to blink? How long have you had it?
Charvel So-Cal (SH6TB/N, killswitch), Jackson RR5FR (TB6/Jazz, Drop C). Joyo pxl pro.
Loop1=Crybaby from hell, Boss PS-5, Seymour Duncan 805 or Green Rhino, EQD Hoof or Earthbound Audio Super Collider. Loop 1 into ISP Decimator II.
Loop 2 (FX loop)-Line6 M9, TC Spark Mini. Loop 2 into mxr 10band. All into a Peavey Triple XXX 212, Ibanez IL15.
