Contacted the Harman Kardon 'tech support', who directed me to contact a local service place. I can honestly say I have exhausted nearly every available resource to get the AVR-1700 working, to no avail. I tried our tried-and-true method of resetting the receiver. guess what? Getting the 'BCO Update' message suddenly. I decided to buy a $20 optical cable to at least allow me to connect my HDMI resources to the TV then pipe the sound from the TV to the receiver. Sound was there, but no video output (HDMI - I didn't try the other outputs) from the receiver. We sort of got used to this 4-6 month ritual of resetting the receiver when this message would appear. I finally came across a work around (posted here) that walked me through how to 'pretend' to update the firmware (it always says 'failed'), but this process alone does some sort of 'reset', and the receiver begins working normal again. several others experienced the same issue, with no help from Harman Kardon.

My continued searches discovered that I was not alone. Because of work and family obligations, this self-fix-it troubleshooting took me a couple months before I finally decided to take it back to Best Buy. After much google searching and working to find a solution, I tried to update the firmware. leaving it powered off for a long period didn't help. After some months of buying the AVR-1700, a 'BCO Update Please Wait.' message came up, essentially locking the receiver. I bought this a couple years ago from Best Buy. Though I'd share my experience with my first (and last) Harman Kardon product. > I tried but it won't even let me turn it off like that On Friday, Decemat 9:43:14 PM UTC-7, wrote: BCO Update message should disappear, and life is good again! The operation will fail, but you will have jolted the receiver out of update mode. If done correctly, you will be looking at the Harman Kardon web interface for the receiver.Ĭlick the Choose File button and choose any random file on your computer. Type the IP address of your AVR 1700 into a web browser on your computer (it should like this: 192.168.1.xxx, with the last three digits based on your individual network). You can do this by logging into your wireless router's web interface, or by using a utility like this one: Using your computer, determine the IP address of the AVR 1700 on your local network. For me, this meant temporarily moving my cable modem and wireless router into the living room and connecting the receiver to my router with an ethernet cable.

For anyone who has found this thread because their AVR 1700 is stuck in BCO Update mode, I wanted to post a the solution that worked for me this morning:Ĭonnect your AVR 1700 to your home network.
