Hi everyone,
I have a 'Monster Power HDP1750G+ Powercenter' power conditioner which is making a loud buzzing noise.
The unit seems to be working fine other than the buzzing noise.
When you plug it in there is no noise. You turn the power switch on, and there is a low volume buzzing noise from the left hand side of the unit. Then after about 10 seconds a relay kicks in and a loud buzzing noise comes from the right hand side of the unit.
I have contacted Monster and they have told me that this noise is the surge protection circuitry kicking in and that I should dispose of the unit.
They have also advise there are no schematics available for this unit.
I have opened the unit up and everything looks clean and healthy (nothing looks blown or damaged).
The buzzing seems to be coming from the section with the varistors, chokes, caps, and relays (circled in the picture)
Has anyone come across this problem with a Monster power condition before?
I am suspecting it's the varistors which is making the noise and needs changing? Am I correct in my assumption?
If so, is it something I should do? Or is it time to dispose of the unit?
Thanks
