There are 3 motorised control switches on this unit. Input select switch, Listen select switch, and the volume control switch. All three have a red indicator on the mounted on the switches. When the unit is powered-on I would expect the three indicators to light-up so that you could see their position. My problem is that none of these indicators light-up. I would be grateful for any response to this posting as I am new to this forum and not brilliant on electronics. Many thanks Tony March
