M040 Hum

I bought a set of M040 monitors, from Thomann in Germany, because they were sold at a good price. I’ve just recently started setting up my home studio. Been traveling a lot with work, the past year, so it’s just now that I have the time to finally make some music. The problem that I have is that there is a hum, coming from one of the monitors. It’s the kind of electric hum, you’ll hear from some, perhaps faulty, power supplies. It’s pretty low frequency, so I'm not talking about high frequency hiss. The source of the hum is the on the back of the monitor. I’ve tried switching power, and audio cables with the other monitor, but the problem persists. I’ve also tried changing location, different power outlets, and settings on the back. No change. Now, Im sure something is wrong because it’s a relatively loud hum. In a quiet room, I can hear it from 3 meters away. Also, the other monitors sounds fine, and there is no hum coming from the back. 
I’m writing here, just to check if there is something I can do before I return the monitor, and also to ask if I should contact the retailer, or Genelec, with warranty matters?
Thank you very much for your help.

Hi Mattias,

I'm sorry to hear about this issue. It seems like you have tried all the tricks, so it is needed to have your monitor serviced. Please contact the retailer to proceed with the repair.

Best Regards,
