tx-nr509 - HDMI totally broken

Seems like i'm not alone in this situation. here's a quick rundown:
1) HDMI was working fine, then one day stopped working
2) If an input is selected which has an HDMI src hooked to it, the receiver will blink "hdmi" for a bit, then display "no signal". The OSD won't show on the TV, and the TV detects no input
3) if an input w/ no HDMI src is selected, the OSD w/ blue screen displays on the tv fine.
4) i've swapped out components (ps3, cable box, wdtv), hdmi cables, even hooked the onkyo to a different HDTV.
5) i've done the factory reset.

Does anybody know approximately what the repair costs would be to get this fixed? has anyone attempted fixing hdmi themselves w/ replacement parts?
