search the web for p/n: 1B248597-1D_TXNR809E That is the correct p/n for that hdmi board.

hdmi sockets are faulty on the dsp board - repair - replace dsp board

It's usually the hdmi switching IC that goes bad on these. Not something you can really replace without the right equipment and knowledge.

If you look on the internet HDMI board failure on these Onkyo's seems quite a regular occurence.

Time to scrap the Onkyo and buy something with a better name - like Yamaha, Denon or Marantz.

Sounds like you may have a bad HDMI card my friend. I had an issue with my HDMI card that was causing blue dots to appear on the dark parts of the screen, when outputting 1080p over HDMI. This is a rather common issue, so it wouldn't surprise me if your HDMI board needs replacement - especially if you've ever experienced the infamous blue dot issue.

You will need to contact Onkyo directly and request the board from the parts department. I was not able to locate a part number for this as we are usually requested to perform component level repairs for these units.

HDMI ports 5 and 6 on the back of tv no longer are working. (We had a series of thunder storms so don't know if that is how they got damaged or if it was something else) but moved HDMI input cable to HDMI port 4 on tv and everything is working again. Service call placed for warranty service on tv to repair bad ports.

1) I bought the same Onkyo model from goodwill a couple years ago and it had the same problem. The solution is simple: Get yourself some Deoxit D5. This is a spray that will clean out all the oxidation in the volume pot. To do this you'll need to remove the cover of the receiver. Deoxit can be bought at guitar shops, or if you know a musician they might be willing to do it for you.

2) User manual is available for download, for free. Google "Onkyo tx-906 receiver manual".
