I just received the new set top boxes and had a technician at my house to install them today. The main box is simultaneously blinking green and red and also a strange sound is coming from the box. It will stop blinking and then start blinking with a light white and green light and then go right back to the green and red blinking lights. I tried unplugging the device, resetting it and nothing is working. This is very frustrating considering the technician was at my house this afternoon!
