I got the Onkyo HT-R590 receiver with my S5400 Home Theater and worked fine since April with my Directv box, Xbox 360 and PS3 hooked up to it via HDMI. But recently I got a new LG 55LM4600 to replace my Vizio and as soon as I plugged in the HDMI cable to the LG my Directv box would not show video only a pink screen then it started working with video but it was all pink. My Xbox 360 works fine but my PS3 just flickers between a black and blue screen. I tried hooking it up to another TV with same results and all 3 work fine if hooked up individually to the LG tv. Any idea what might be the problem?
