ES550 and ES700 not powering up

[Anonymous user]

I am having trouble with no less than 3 of these units. They all exhibit similar faults in that they will not power up correctly. When plugged into the mains and switched on the green light will flash and then when the unit tries to switch on, will buzz loudly and click several times before switching onto a continuous beep.

Occasionally I can get one to work after several attempts. I am sorry if this has been posted before but I have performed several searches for this.

Help please.

The product might be defective, have you tried to ask for a technical support to help you fix it up or change it?
