Greatly appreciate your help!

Got the amp July 2016. There were a couple of instances at church when someone turned off power supply before I could properly shut it down. Hasn't worked 100% right in 6 months. I'll have to try the tubes first as shipping it to a dealer would be costly. I do use the recommended digital cable which I thought of replacing but the noises were still happening even after I pulled cable out and restarted amp.

my DT25 head just cuts off and starts making a weird chirping sound. Almost like the sounds an old internet hookup/fax machine used to sound like. Makes the sounds even after I unplug the L6 XLR cable. It seemed to start failing when switching patches on my HD 500X. Got worse with my Helix. Help!

I use a HD 500X with a DT25 head. Has worked great for last 6 months but after a rehearsal at church it stopped responding right when we went onstage to play a second service. Everything lit up but no sound. Unplugged and powered up the 500x....nothing. I had to leave the stage and go turn the amp off and back on. The 500X finally worked. Just had a different band practice and same thing happened. The display started flashing different settings, volume got real low and then came back. I'm perplexed. Am I possibly switching too quickly on presets when trying to find the right one?
