I really need to get to the bottom of this issue once and for all. My tv recently stopped being able to communicate with my Onkyo Receiver this weekend after connecting a pc through the receiver to my tv via HDMI. There is a major handshake HDCP issue between the LG and ONKYO. I was running live tv via a CableCard tuner and there was lots of hickups going on then the screen would go fuzzy and stuff and audio would sputter. Now nothing sinks with AVR. The TV works great with components hooked directly to it but no longer will it sink with my AVR. I want to re-load the Firmware or do a Factory Reset but I can not find any information on this model. It has not given me any trouble whatsoever for over 2 years until now. PLEASE HELP! I have done everthing I can think of to troubleshoot it. The AVR will still sink up with another model tv so I have eliminated it from my list of problems.
