My receiver does not show "DTS HD Master Audio" in the display, even though the Blu-ray disc should have this format. Instead, it just shows "DTS".
With some Blu-ray discs, you have to go to the Settings Menu of your Blu-ray player and select "Bitstream" or "Bitstream Native". This will carry the DTS HD Master signal to be decoded in the AVR, and the AVR front panel should show the correct text.
My AVR 170 shows an update warning screen “BCO UPDATE” and freezes. What can I do?
Please perform a reset. 1: Press the front-panel Standby/on switch to place the unit in the Standby mode (the power Indicator LED will turn amber). 2: Press and hold the front-panel Surround Mode Button for at least 5 seconds until the RESET message appears on the front-panel message display. Now the receiver should function correctly. (Radio presets and other adjustments will be lost, so these must be re-entered). If this reset does not solve the problem, please contact the Harman Kardon helpdesk. Please note that a software update can only be performed with a USB memory stick with files downloaded from the Harman Kardon web site. It is not possible to update through direct web connection. We are sorry for any inconvenience you may have experienced.
Is it sufficient to put the AVR into standby, before connecting a Source or a TV?
For your personal safety and to avoid possible damage to your equipment and speakers, it is always a good practice to turn off and unplug the AVR and ALL source equipment from the AC output before making any audio or video system connections.
I have downloaded the Remote Control App for my AVR, but it does not work when I open it and try to control my receiver. What can I do?
The AVR Remote App controls your receiver through your smartphone, which communicates via your wireless home network. Please make sure that your AVR is properly connected to your network router, with cable for the smaller models. If you have no wireless home network, you cannot use the app.
Sometimes when I watch HD or 3D material, I can see white specks or "snow" on the screen. What can I do to avoid this?
Try another HDMI cable, and make sure that it is a high-speed version. This solution usually solves the problem, which is caused by insufficient cable bandwith.
