Hi all, sorry if this is not the correct category for my post.
All of a sudden, or possibly caused by a malfunctioning HDMI board on a Denon receiver, the HDMI inputs on my European KRP-500M are not working properly.
The symptoms are as follows, for a set of my devices (LG Blu-ray player, PS3, Apple TV, HD Cable box)
HDMI1 - LG shows start-up picture, then goes black. PS3 always black, Cable box shows start up picture then black, Apple TV works fine
HDMI2 - LG always black. PS3 always black, Cable always black, Apple TV works fine
DVI - All works fine
DVI is connected with a standard DVI to HDMI cable.
I have tested several HDMI cables, and the equipment works fine on other screens.
I have tested all sorts of factory resets on the sources, power on sequences etc.
As you see, the strange thing here is that the Apple TV (and at least one laptop I tested) works fine on all inputs.
The problem sounds kind of HDCP, but I cant figure out why the Apple TV would work, and why the DVI input would work...
Any suggestions as to what I could try would be greatly appreciated.
Thank you for reading!
