I have Onkyo TX-NR616 receiver with bad HDMI board. I've tried baking it in the oven to try and see if it would fix it but i still don't have audio, USB or NET. Video is working fine. I cannot replace the board or send it to Onkyo for repair. Is it possible to modify it so it could be used only as an amplifier to receive 7.1 analogue signal from PC and be able to only control volume. Here is the service manual with boards diagrams www.drive.google.com/file/d/0B_MMtEoxVbyqR3c4OG8zbHNRRkU/view?usp=sharing
