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 just ordered a brand new DSL40CR, took a week to get here, it finally gets here and theres no sound? Theres power to amp, everything lights up, and it even makes a faint popping noise when I'm turning it off, but its not picking up my guitar or anything of the sort, can someone help me please.
