I have an onkyo 705...it started flashing random stuff across the display and the light around the control knob flashes in sync w/ the display...it only starts doing it when I do ANYTHING concerning hdmi...simply bring the menu up w/ hdmi on it and it starts freaking out. I took it to a local A/V repair shop hoping it would be something simple. The guy said it needs a new "hd board" does this sound correct? where can I find a new hd board and would it be difficult to install? or just screw right in and plug in somewhere?
Thanks for all the help, have a great day...
