HDCP was a crappy idea that causes a lot of these issues. As the HDCP is part of the HDMI chips there is no workaround or firmware update.
My next thought is to see if this is a 720p set. http://www.samsung.com/us/support/owners/product/LN-S4092D was strangely vacant on that.
Looking in the product manual it looks 720p so here's the issue. Your receiver may not pass along the 720p information to the source so it's possible the source flips out to 1080p and you get no picture. Given the gear is dated and no firmware may fix this, MANUALLY set the sources to 720p.
Hope that clears it up.

I have the titled Samsung LCD TV. It's probably over 10 years old. When I hooked up a new Denon Receiver it only the sound was heard, no picture with HDMI cable. When connecting Cable box directly to the TV the picture and sound e=was fine. Then I tried a Sony new Sony receiver and the same this happened, No picture only sound.
Is this TV not compatible with the newer receivers ??? HELP !!
Thanks
