Guitar and lead both work fine however my Marshall DSL40 (purchased Dec 2018) has stopped working, all lights work however there is no sound. High power output also makes strange popping/crackling noises when idle, also as of 2 weeks ago the amp would randomly but rarely make a clicking noise when in standby, this stopped a week later but I had previously never ever heard this noise before. The standby also emits a quiet hum.
I was just playing my Epi on the Acoustic setting and all sound went out and the screen and buttons started flashing. Tried pluggin/unplugging. Pluggin into a different outlet. What the hell just happened?
