Kardon AVR 146 - No video signal with HDMI
I had the same problem with a Kardon HS 200.
The solution to my problem was that the Home cinema system need an uptade for connection with (in my case) a philips television.
I think the best thing to do is to cotact Harman or your supplier.
This update is quickly done by reading the adapted file writen on a CD-ROM. Good luck !
If you want, I can try to send you the file adapted for my system, but I'm nos sure this one could solve your problem on your system.
Sorry for my poor english, I'm french !
