Denon AVR-1912 E2/EA

[Michael Studio1]

Later - John - I have examined the AVR which has an INPUT SELECTOR knob. By-Pass or FL (or any other of the 7Channel Amps is not an option there. Good thought though! Thanks. Michael Studio1 UK 19:41BST 06/05/2018

Yes, Dries, that is just what I'm relying on. In order to make sense of it I simply must trace through the Cct.Diags. to check the routing. The fact that when it was re-assembled the two Test Tones were audible at the two electrolytic caps I had replaced: C799 page126/K2 and C831/K3. Now, suddenly (well, nearly suddenly as this happened a day-or-so after re-assembly) the Signal Test Tones are not audible. These two Capacitors are the last reasonably accessible probe-able points before both tones go into IC30 page126/B5. This is what is so galling in this test procedure. I shall continue my probing tomorrow. Michael Studio1 UK 21:50 08/05/2018

Are we talking about the Denon's test tone that alternately punches a test tone to each speaker

No, Dries, I have a FeelTech FY3200S Dual Channel Arbitrary Function Signal Generator/Counter so I am injecting a 700cps tone in the Right Channel and a 500cps tone in the Left Channel. This is usually at VAUXR and VAUXL which are on the front panel and are the Inputs selected by default. The Inputs are changeable by the INPUT SELECT knob - so I have also been trying CD Inputs which are also Analog. I am probing for these Test Tones with a simple ex-PC monitor speaker and a home-made probe with a series capacitor in it. Michael Studio1 UK 22:05BST 08-05-2018

Good idea Dries.

To clarify, Denon has a test feature that sends a brief sound pattern out to each speaker for purposes of verifying that each speaker is connected and for adjusting volume levels.

My remote control has a test button to initiate this test which puts out a white noise for two seconds for each channel.
Yours may be hidden under a menu somewhere.
If you are able to read on screen graphics on your tv (via Hdmi) it may be of great help.

Thanks for this suggestion, John and Dries. The remote for this AVR is "somewhere" I am told, but I haven't seen it - so must institute a deep search! However, as you suggest it "may be hidden under a menu somewhere." So I'll look there as well. Today is obviously going to be one of 'search' - maybe even of 'find'!

As You Know says if your lab computer has a hdmi port viewing the menus on the screen is a big help. If you don't have the remote the menus can be navigated via the buttons on the AVR but I find that very clunky

Hello Dries - your comment: "As You Know says if your lab computer has a hdmi port viewing the menus on the screen is a big help" Now that's very interesting. The Lab PC was built by my son Maxim (currently at Guildhall University London) using an ASUS M2N4-SLI MoBo. Its PCI Express slot has an ASUS graphics card with VGA, HDMI & DVI sockets. The ACER VGA monitor is screwed to the lab wall. There's an RS232 socket for the UT61-E DVM and various USB ports with which I view the results from the Endoscope. There's no HDMI "IN" port. How is the HDMI port utilised to view the menus of the AVR - please? Maybe I should get a card for the Lab PC which has an HDMI 'IN' port? (could be useful?)

So the Asus PC's contents are viewable on the wall mounted VGA monitor?

Then plug a HDMI cable into the back of the Denon and connect the other end to the graphics cards HDMI slot. With a bit of fiddling you should be able to see the Denon's menu on the monitor

Well, Dries, I thought that with the HMDI socket being in the ASUS Graphic Card along with the DVI socket and the VGA socket that this was an 'OUT' HDMI socket - but I'm not really 'up' on HDMI. Please advise? Michael Studio1 UK 11:58BST 09-05-2018

Hmmm, you could be right. Google the graphics card to see. Maybe there's a way to use it as an IN

 

[bushtech]

There is something called an EZcap which is actually a hdmi recorder but which can do passthrough so you can see the stream on your screen

This is possible that the HDMI socket in the Graphics Card is a two-way thing. After all the Graphics card is slotted into the PCI-Express x 16 slot which, of course, works in both directions. Probably a case of 'suck-it-&-see'? If, then, I operate on the basis that the HDMI socket is both an 'IN' and an 'OUT' how are the connections set up - I'm taking it you have done this?

Thanks for this suggestion, Dries. EZcap is a blast from the past I think - and I do believe that I have one . . . somewhere (rather like the Remote for the AVR) Michael Studio1 UK 13:58BST 09-05-2018

I have Googled this ASUS Graphics Card (ASUS Graphics Card 210-SL-1GD3-BRK) and looked at the specs. but there is no mention about the capabilities of the HDMI socket - even in the 22 page Manual - which was available to open in 150 different languages - maybe I exaggerate. So the answer still is to re-install the Graphics Card and see what is possible. Have you any advice on this? Herein I'm getting somewhat distracted from getting the AVR working again . . . .

If you had a TV with HDMI slots you plug one end of the cable into the HDMI OUT slot of the Denon. The other end of the cable you plug into a HDMI slot on the TV taking note of the number of the HDMI slot (1,2,3 etc) Now you go into the TV's menu and under the INPUT section you select the relevant HDMI slot. Then you push MENU or something on the Denon's remote and the Denon's MENU should pop on the TV

Thank you, Dries! We do have a T/V with HDMI input, but it is several metres from the Lab. So I shall go back to my original plan with FeelTech Signal Tones, DVM and Probing amp. and just find out where I am in the great scheme of things! Michael Studio1 UK 15:32BST 09-05-2018

Best of luck!
