Question about Harman Kardon AVR 135 Receiver

Open Question

AVR receiver will not play sound.

My HD picture shows on the TV but no sound is coming from the system. Also, the system display only shows analog (not Digital). The DVD player still shows Coaxial and the radio works. I do know that my 9 month old might have pressed something on the remote but I have checked almost every button. In the manual it states that I may need to reset it but then I will have to configure it. This will be hard since I cannot get an on screen display.

SOURCE: OSD not working (black screen)

Your 635 will not display the OSD screen through component. You must use either s-video or rca. It won't upconvert the screen menu this route.
I had one up until a week ago. There are two outputs on the back specifically for the OSD screen. I used a separate old 13" TV with s-video to do my setups. Hope this helps.

SOURCE: My Harman Kardon receiver (

I used the live chat and the problem was resolved.
Usually the problem are strands of speaker wires which cause shorting and protection shuts off the receiver in order to prevent damage. There was one speaker that I repositioned recently which was causing shorting. I twisted the wires and tightened them in place and my receiver has been working w/o a glitch. I was lucky that I did not have to check all the wire strands on the receiver and all the speakers.
Problem solved and I learned valuable lesson.

SOURCE: humming noise

Usually Humming noises come from frequency interferance.  In this case it is being caused by your input sources.  A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.

AOC PD4264 Screen fault

Extremely blue color temperature that cannot be adjusted; some false-contouring artifacts in dark scenes; no picture-in-picture; limited connectivity with just one DVI and no HDMI inputs.
If use as a TV monitor:
The number of colors you can display is controlled by the video card installed in your computer. In order to display more than 16 colors, the proper video card driver must be installed. Contact your computer or video card manufacturer to obtain the latest driver from them.
If you are watching standard-definition or Cable/RF signal on an HDTV, the picture may appear to be of poor quality. This is because the TV is designed for viewing HD or at least digital content. Your best bet would be to upgrade to a Dish Network HD receiver and connect it to the TV with an HDMI cable. Similarly inputting analog signal to TV from your DVD player will not appear to be of great quality. A newer DVD player would most likely have component video output which would look much better. To get even greater quality, an upconverting DVD player connected with an HDMI cable would look the best. You could also upgrade to a Blu-ray disc player, which is capable of playing HD Blu-ray discs as well as DVD's at higher resolution. A less expensive choice could also be a streaming media box.

It sounds like you arent using the correct ports for a HD tv or arent using a HD digital player or HD cable. Still having problem let me know but thats what it looks like to me. Do you have anything plugged into these ports from a HD device? DVD,Digital Recorder, etc?

I just order a hd flat led\lcd tv and would like to know if i could hook my pioneer stereo tuner control amplifier to it instead of buying a separate theater system for the model cx-790.

I can't even find a picture of the CX-790 but the quick answer is a rhetorical question - why do you need to have them connect?

This is all food for your thought. Choose wisely going forward because you will either love or hate your system based on how well it serves your needs.

I'm sure your present TV-related programming comes into the house through a Cable / SAT box, so consider THAT as the audio source (discounting the TV) and route its best audio to the receiver. How do you do it now, I wonder? A new TV need not change the audio question. Your new TV, if it has speakers, could receive it's -box audio through low-end RCA cables in case you just want to watch talk shows or news without the audio system on.

If your TV actuall tunes it's programming via an antenna then it becomes an audio sourc of unknown capability at this point in the conversation. It could have analog and/or digital audio output or not. Treat it like a sound source as you would, say, a CD player.

Your Pioneer is just the sound end. If you want an immersive surround audio experience you do need to upgrade the sound end but not because you have a hi-def TV.

Pretend the TV is just a light show, because that's all it is. Some TV's are just monitors so the question of interaction wouldn't even come up.

The best end result for both watching and listening to high-end multichannel video is to run the absolute finest unaltered video from the source to the TV/monitor and the absolute best digital audio to a quality multichannel AVR with good speakers. The AVR will need a minimum composite video input on the TV so you can manage the AVR. Anything higher is a waste of expensive cable. Mimimizing 'hops' and interconnections lends a better signal path and fewer problems.

Denon avr-3805 suddenly picture went out on tv (says no signal). Denon shows 'voff' on the screen. I cant figure out what happened.

I called customer support and they had not heard of this problem, and could not even tell me what the "V.Off" showing on the display represents. But, . . . the problem was solved by resetting the memory - by powering off, and powering back on while holding down both the Mode and Analog input buttons. Although this wiped out all my settings, the "V.Off" on the display disappeared, and the video now works. Problem solved.

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

Adding another device to the system

Well, if analog works for you connect the CD player's analog RCA cables to the VCR inputs.

Can you imagine why you NEED to have the TV audio coming into the receiver from the TV? Are the TV's audio system or speakers superior to the audio section of every other source of TV-related programming? We hope not. Does the TV receive any programming that the receiver can not? Maybe games. I imagaine this MIGHT justify running analog TV audio back to the receiver.

Your cable box and your DVD player have both digital and analog audio outputs. The gray area is what your TV has for audio inputs. It could survive with simple RCA analog audio in from both and none to or from the receiver. Then you could watch Lo-Fi cable and DVD's without the receiver turned on.

That would free up the TV analog audio input for other things.

I imagine your DVD player is using one of the digital inputs on the receiver. If you have one each optical and coaxial audio output among your DVD and Cable Box you could place them in the two available diigital inputs.

Now, what about the CD's digital output? For stereo music you're not likely to be able to hear any difference between it and the analog input BUT it can still be connected digitally IF it has a coaxial output. Coaxial digital inputs can be shared.

Get an RCA-splitter and join the two units entering the coaxial audio input just before they enter that connection. Either will work just fine if you TURN THE OTHER ONE OFF when you want to us it.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

Convert normal tv to hd tv

If the set you are trying to convert to HD is just your everyday standard VHF/UHF analogue TV - basically forget it! I am given to understand you cannot make your standard telly show HD pictures.
Sorry! That is, of course, anyone else knows different.
