Help! HOF Mini Reverb pedal not working

I recently bought a TC Electronic HOF Mini used and it worked fine for a week. I used it thrice on gigs and once at home. Beaming tones on to the pedal from my android phone worked fine too. However when I plugged it in today it doesn't work when the effect is engaged (no signal at all). It works in bypass mode. I plugged it in to my laptop with the TonePrint app installed - the app seems to recognize that the pedal is connected and beaming is also seemingly possible. But no signal seems to go through from my bass when the effect is engaged! What could be the problem? I'm not very familiar with effects pedals and this really has me upset. Would greatly appreciate some advice..

 

Thanks for your response. I have tried beaming other prints (via my phone and via computer). Via phone, I did not get the flashing green light. Via computer, the TonePrint program says "successfully loaded print" but there was no flashing green light on the pedal (not sure if it's supposed to do that when loading a print via pc).

 

No, I'm not getting the flashing light at all. It worked fine up until today

 

Could a faulty power supply be the culprit? I will check with another power supply as soon as I can get my hands on one.

 

Thanks for all the responses. My power supply turned out to be the cause. Replacing it fixed the issue. So relieved!
