I had a similar experience to jwienand.
We had some bad storms a couple weeks ago. One lightening strike went up the coax from our cable blew two splitters then went upstairs to the DVR, out the HDMI of the DVR (killing the hdmi there) into the 2310 and killing all the hdmi ports in the process and also killing the hdmi of everything connected to the receiver (epson 6100, ps3, and xbox 360!). Interestingly, this was the only room affected and ONLY the hdmi was affected on all of the electronics. All other inputs/outputs function normally!
Anyhoo, I am going to contact a Denon parts distributor later today and see what the pricing for replacement is. I'll post their quote and compare it to the $90 at the link. Think I'm gonna do this myself, too
The phone number Denon gave me to call ended up being the pacparts.com landline (the same company in the previous link) so the price was the same. The part must be ordered from Denon as pacparts does not keep it in stock and it will take approximately 10 days from the purchase date to receive the part at my house. Also, this part comes with a 90 day warranty.Edit 2:
They can no longer get the part from Denon and instructed me to contact them directly. Looks like the only way to get a replacement part is buying a used unit privately or on an online auction site.Final Edit:
Contacted Denon directly again this morning explaining the situation. I was connected to the parts department and they informed me that particular part is no longer available for purchase. They can refurbish the board for $90.09 (amazing coincidence!) plus shipping both ways. Turn around time is 2-3 weeks. I think I will just purchase a new receiver instead of messing with shipping. And it won't be a Denon. I loved that thing but $800 is just too much to spend twice in 3 years for me (no fault of Denon's that lightening took it out, though).Edited by ataxic_dentist - 8/1/12 at 6:15am
