Dear Sifus,

Since last week, my Denon AVR having the below problems or could it be other equipment?

- after playing DVD or CD Audio for about 1/2 an hour, the AVR suddenly output very loud sound of "shhh, krak krak" till I have to power OFF the AVR.

- while the DVD player (Pioneer) is playing with its display showing the time lapse running as usual. (no freezing or hang)

- sometimes, my LCD-TV blink display errror message "No input signal " in about every 2 second and the AVR keep on "switching". While my Pioneer-DVD red HDMI LED keep on blinking and my Denon output sound for 1 second, then goes quiet, then output sound for 1 sec and repeatly.

Also, I noticed, if I did not switch ON (or OFF) my LCD-TV, just the DVD player and AVR, no such symptons found but just the sudden "shh krak krak " sound after more than 30min running.

If I directly connect my DVD player to LCD-TV, no such symptons found.


DVD --->HDMI--- Denon AVR --->HDMI---> LCD TV.




To the sifus here,

I am at lost here to troubleshoot further.


What do you think? My AVR spoilt? LCD-TV? Or cabling?


Thank you in advanced.

Dear Sifus Mpyw & Kianwee,


Thanks.

I will read up my manual on how to reset my Denon1909. (1st time for me!)


Before I forgot, I will get this sudden loud "shhhh, crack, crack" sound at half way of playing 1 DVD movie or CD audio. (not even reaching 1 hour yet!)

The AVR display the "normal" LED display info, just the speaker output extremely loud "shhhh, crack, klack" sound.

Sometimes, if I played CD-Audio, after about 30min, the AVR output a loud "eeeehhhhhhhhh" while my DVD player still running fine. Just no more music from the 5.1 speakers! (even my original volume was set lower eg. at -35dB) but the "eeeeehh" was way louder!


Symptons Found:

1) sudden loud "shhhh, crack, crack" if playing DVD-Movie, after half way only.
2) sudden loud "eeeehhhhhhhhh" if playing Audio CD, after half way only.
3) If I turn OFF the AVR and ON again, the DVD or CD-A fine for a while before the next error again.
4) My LCD-TV will display "No signal ..." and blank out for about 2 sec, then re-appear with "No signal .....pls check ..."
5) MY Pioneer DVD HDMI LED keep on blinkling ON and OFF while the sound output keep on playing for 1 second, then switch to silent, then back again, repeatly non stop.


Any other Sifus comments?

Over heating AVR?
HDMI cable faulty?

Thanks to Ronaldjoe, choontoy and anfieldude.

Sifus pointed to the below.


(1) my HDMI cable problem. (oh no have to buy another HDMI cable?)

(2) my HDMI board! (ohh my god! hv to pay $$$)

(3) my AVR "video convert" function set to disable? (reading the manual now)

Yes, for the Denon AVR, the GUI work fine.

It is just out of nowhere a sudden ear piercing sound emit from the speaker!

I need to turn OFF the AVR and ON again, then back to normal for about 30min before it happens again.

Dear Ronaldjoe,

Answer :

1) No, I do not have other HDMI source, only from my Pioneer DVD
2) No spare HDMI cable too, have to buy I guess!

Wow, that great, I wish the same as I was not satisfied with my 1909.

I'm using Usher front and Mission Centre but lousy sound!

I wish I can top up and change to HD capable.

Do you know if CMY let me do such request?

Yes, the GUI is run directly from the AVR front LED display. (since I cannot get my LCD-TV to display the GUI)

It keep on displaying dark screen and "No input....pls check...." and goes blank again.

My DVD is Pioneer DV 420V-K and I believe there is a Component Output but I do not have the Component cables!

Dear Mikapoh,

Thanks for sharing, I will reset the AVR tonight.

Guessed our 1909 not so stable after all?

Actually I am not satisfied at my 1909, mine a 5.1 setup (Front=Usher, Centre=Mission, SW=Roger) and the sound quality cannot match my RM400 Altec Lansing (when listening to CD-audio)

Maybe something very wrong?

Choontoy,

I am puzzled too, my PC 2.1 better than it!

My Front = Usher V-601
Centre = Mission
Surround = Panasonic
SW = Roger

Anyway, maybe I use it in my living room or there something very wrong with my AVR!

Dear all sifus who responded to my SOS call,

Thanks.

FYI, Master Chew help me to diagnose and solved this problem.

It is due a faulty HDMI cable. (not even visible to normal eye sight) And the HDMI interface is very fragile, so be extra careful and do not pull out or push in this HDMI like it is a RCA or Component types!

Hope the cable did not damage my AVR in long run and it's electronics as it gave out extremely loud sound many many times till I have to OFF my AVR.

This cable is from Pioneer DVD- 420V

To anfieldude ,

I do not have a CD player, just a DVD from Pioneer HDMI type if not mistaken 420V?

Anyway, thanks again for your valuable comments & suggestions.

No Master Chew from WKH!

Added on October 9, 2009, 2:31 pmNow, my next problem and I need advises from Sifus here.

Sorry, I am a newbie in component AVR.

I feel my system still lack of umphhh! (lack of Bass and Treble) especially when on Music (CD-A)

Front = Usher V601
Centre = Mission
Surround = Pana
SW = Roger

I have to manually set the SW dB to max at 12 to get some Bass

Anyone know how to get more Treble out? Or how to set ?

Can the Manual Equalizer help to pump out more Bass & Treble?

What the best ? The Auddessy result not so good to me.]

Thanks.

Dear Junwei,


Since I'm new to AVR (previously HTiB & HTPC), I just learn to listen via trial & error methods.

My components not match well? I hope to find out too!

The bass when viewing DVD are acceptable but not when listening to Audio CD.
When listenning to Audio CD, it lacks of treble and the bass is acceptable if set my SW manually to max, that is +12dB.

But there is no sharp and clean treble which I can obtain from my Car Audio System (something like tweeters) or even my HTPC obtain better result. I am puzzled too a few $$$k system compare to $1k system!

Also, I noticed my Denon Manual might not be new as there was some pencil writing and remark on some of the pages! (but I bought it brand new!)

Anyway, my answers :-

1) what's the dimension of your listening area? Room or Living room?
ANSWER : My squerish living room is too open actually. 20x28 feet, but with opening (no door) to Kitchen and to staircase of 1st floor (typical MY terrace house)


2) what's your roger SW model and size?
ANSWER :
Model : Roger ASB 100.
Power amplifier : 100W RMS (8 ohms) .
Frequency Response : 30Hz-200Hz+/-3dB .
Crossover : 50Hz-150Hz (variable) .
Crossover Slope : 12dB per Octave .
Driver Unit : 254mm Long Throw .
Function : Power (On, Auto, Off), Phase (0, 180 degree), Level Controller, Crossover Frequency, Controller .
Inputs : Hi Level (Speaker) In, Line (RCA) In .
Dimension (WxHxD) : 290 x 335 x 325 mm
Weight : 12 kg (Net)

Front Speaker : Usher V-601
2-way system :
tweeter 1" (9930-20NC), low-bass 7" (8935A)
Sensitivity 86.5dB @ 1 watt/1m
nominal impedance 6 ohms
frequency response (-3 dB): 42 Hz ~ 20 kHz
power handling 70 watts
crossover frequencies 2.22 kHz
weight 12.6 kgs (per speaker)
dimensions (wxdxh) 23.8cm x 29.2cm x 44.5cm



3) what subwoofer cable are you using?
ANSWER : I'm using the given RCA-RCA cable (Denon SW Out straight to Roger ASB) Actually, I'm not sure the best way to connect up my SW as there was more than the RCA interface. I will try to share it diagram later.


4) where is the subwoofer located?
ANSWER : SW located at about 2m away from the AVR and FL, FR.


5) front and rear speakers model.
Front = Usher V601
Centre = Mission
Surround = my previosu Panasonic, 6 Ohm type.


6) AVR level for each speakers.
ANSWER :
These are not Audessy value as I changed it manually or should I use the Audyssey?

FrontL = 8dB
FrontR = 10
Centre = 7
RearL = 8
RearR = 8
SW = 12


Thank you ina advanced to those who is willing to read and comments.

Sorry, I failed (do not know how) to insert the image of the SW wiring diagram, so I can only provide the website link.

Thanks.

Dear Sifus,

Thanks for the comments.

My AVR has only 1 port labelled as SW. Therefore I connect one RCA cable output from AVR to one RCA input of the SW. Wonder how I utilize & connect the RCA-Y type?

Yes, bass for movie is acceptable but not for CD music (especially 80' euro/dance CDs)

Even basic CD Audio sound (current singer /normal CD) lack of treble and bass and just on par or a bit lower with my HTPC.

My HTPC was power up with Altec Lansing and a "reasonable $ good" 2.1 system, tiny satellite speaker by "Hi Tech" if not mistaken, bought from Hi Way Laser (or Style Laser?), Cheras a few years back.


Phasing problem? May I know what is Phasing? There a "Phase" switch at my SW too.

There are quite a few connections point at the rear of my SW, which I only use one port, SW.

Wonder what are their purposes and how to connect?

My Usher power hungry? Hmm, I 'm puzzled too. Or I must set the volume higher to "hear" it capability? (my usual volume set around -25 to -35dB range)

Bass and treble set it flat? I set my treble via the Equalizer (increase to V or n shape), but no different at all. My settings wrong?

Yes, a few pencil handwritings on my manual. Bought from CMY-Sg Way but the warranty card is by CMY Penang!

Dear tracktion3 ,

Thank you for sharing.

I think my Sub comes with only 1 RCA port only, no left or right.

And what's MA RS6, the DSP?

My normal Volume ranges from -25 to -35.

Dear Traction3,

Thanks for the suggestions.

I think I'm using No 2 setup.

Anyway, I will go and buy the "RCA split to 2" tonight and try.

Actually, the manual diagram from Roger is not the same as the actual Roger SW, physically.

I will try to take a picture of the rear on my Roger SW and share here.

Bro,

I'm failed to find the Y-RCA cable in local stores. Maybe I need to go Jln Pasar or LowYat, KL? (I am in Bkt Rimau Shah Alam)

Anyway, I will share the ASB100 SW rear diagram here. (attached)


Opss, anyone willing to guide me how to insert pictures here?

I only managed to attached but not share the pic in same post reply.


Also 2 pic of my Phase Tech 2.1 Satellite speaker which amazingly sounded better than my Usher + Denon!

Wonder anyone seen this Phase Tech system before, bought more than 8 years ago and sound good till today!


Anyone care to advise me on how to get Treble out of my system, and how to use Equalizer?



Thanks.



Attached thumbnail(s)

Bro,

You sure?

Hmm, wonder why they include the "dedicated SW input".

Anyway, I still would like to test the 2 RCA input (red & white)

Do you think it will be the same result?

For movies, it the bass is acceptable after setting the SW 12dB.

But for Audio CD (song & music), it lack of bass and treble.

Do you know how to get more Treble out from Denon?

Can I use Equalizer? (currently Flat).

And when I set the Equaliser to the max or opposite, it seem no different at all (SQ stay same) or my manual method is wrong?


Thanks.

Bro,

Thanks.

Yes, there is Direct Mode in this Denon.

It sounded average and not much better than my good old RM1k 2.1 system.


Do you have experiences in Equalizer?

Should use or just leave it at it is?

Dear Tracktion3,

Thanks for sharing your thoughts eventhough I do not quite understand the Xover, 80, 90 and the hump at 90Hz.

Bro,

Wow, thanks, guess I have a lot of catching up to do!.

Added on December 7, 2009, 6:42 pmDear Traction3, (or other sifus)


I seldom use my Denon AVR.

Yesterday, I discovered something wrong with my AVR and that my AVR will emits loud noise once a while until I have to power OFF and ON again.

=> Eg. now playing CD audio/MP3, fine for about 10 min (after ON), then suddenly my rear surround speaker (5.1) suddenly emit loud noise.
=> I will have to power OFF and then ON the AVR with the CD playing (no stop DVD player), then it is fine. (no lmore oud noise)
=> but it will appear again, after about another 30min (maybe randomly)

The sound from the speaker, sounded like someone blowing loudly into a MIC . I'm sure it came from the rear surround and not Front Speakers.


What could it be?

My speaker cabling?
My HMDI cabling?


Pls let me know if you encounter such problem(s) before and what possibility it might be?

My AVR warranty from WKH will expire in few months time.



Thanks.
