I'm an Onkyo fan and I have an Onkyo TX NR808 AVR and I have owned a few Onkyo HTIB's... I have never had any trouble with any of my equipment, but probably the biggest problem Onkyo has is their HDMI boards are known to fail quite often. I'm guessing that is what happened to you. If you don't use all 4 HDMI ports just use one that is working, if your system is still under warranty call Onkyo and see what to do to have it repaired. If those options don't suit your situation then I guess its time for you to get upgraditus and start with a quality AVR.
