Hello, and welcome. My name is XXXXX XXXXX X’ll be assisting you today.
First, a brief overview of the process: This is a live chat format, so I’ll need to communicate back and forth with you. You’ve already paid a deposit or membership to post your question here. I am an independent tech, and am volunteering my time unpaid until our chat is concluded. At that time I’ll request you click the EXCELLENT smiley face to close out our chat. It is my intention to solve your problem with a quick, honest, and helpful answer and my goal is for a rating of Excellent Service. You may receive an email survey after our chat, if you don’t feel I’ve earned a “10” rating in all areas, please let me know what I can do to better meet your expectations.
Should you feel the need to provide a negative rating of Bad or Poor Service, please wait and let me know what I can do to clarify or more thoroughly answer your question instead. Remember, you are rating me personally, not this site or your product and a negative rating will not initiate a refund. Please know that not all issues can be fixed online; in those cases of a hardware failure, I’ll troubleshoot and diagnose the problem, and provide a practical recommendation for how to proceed.
My livelihood depends on your positive feedback, so your satisfaction is my highest priority. Let’s get started!
Hi there, sorry to hear you're having trouble with the Denon,
there are a few possible issues here, but unfortunately the most likely one is simply that the hdmi board has failed.
This is actually a fairly common problem, and is usually caused by a power event (static shock or a power surge), though it can be caused by overheating as well.
There is one thing we can attempt here, which is a microprocessor reset,
Power the denon off (using the on/standby button), then press and hold the Preset Channel 2 and 3 buttons, while powering back on. Keep holding until the display starts flashing, then release.
Overheating is just one possibility, I was just trying to explain some possible causes of the issue so you have some background information.
Please try the reset, which will help if this is a memory/processor glitch. If that does not help, it would unfortunately confirm a hardware defect. At that point, repairs would be required, but because of the age, it won't be a practical fix. You'd be looking at $300+ in parts and labor to have the hdmi board replaced. You would be better off investing in a new receiver at that point, or using a workaround connection (run everything into your tv via hdmi, then a separate optical cable from the tv or each device, back to the denon for audio).
No, you would not.
Denon makes those parts available only to authorized repair facilities,
and even then, only rarely so. Typically for hdmi issues they make the shop send the whole receiver in for factory service,
You might come across another unit of the same model on ebay or craigslist by chance, one with a blown amp perhaps that you could scavenge a board from.
However, it wouldn't hurt to still call denon,
you are just barely past the 2 year warranty,
and this hdmi board problem was somewhat common with this model. So, they may be willing to extend a bit of consideration for you in this case. No guarantees, but it doesn't hurt to ask.
If you want to try giving them a call, the number is(NNN) NNN-NNNN/p>
Despite this issue, I would still recommend Denon over any other brand.
I've been an authorized dealer and installer for all the big brands for 10+ years,
and in my experience, denons are still the best performing and the most reliable.
I would recommend Pioneer next, followed by Yamaha. I would avoid onkyo entirely, nearly every onkyo I've seen has had a hdmi board failure or overheating failures.
HDMI based devices (not just denons) are very touchy when it comes to power, even a static shock from touching the receiver (or any connected component) with a finger can fry these boards, I've seen it many times before, and it can happen even when connected to the best surge protectors. I've replaced many receivers for clients over the years from this issue.
Hopefully Denon will help you out,
if the first person you speak with won't help, ask for a supervisor, and if needed it wouldn't hurt to threaten (or even follow through) with posting some negative comments about their product reliability and support on social media.
My pleasure, glad I could be of help.
If you have any other questions, just let me know. Otherwise, please do remember to rate my service prior to logging off, hopefully I have earned an “excellent”. I also invite you to contact me directly with any future support needs at http://www.justanswer.com/electronics/expert-p0llinate/
