SOURCE: Blown Channel on an amplifier

Look for low valued resistors that may look ok, but be open. Check the emitter resistors (.22 or .47 ohms). Check the transistors in the driver circuit as well.

SOURCE: Loss of volume on left channel

please repeat speaker setting from your manual and confirm that left channel is ok.-invert left channel plug with right channel plug if the problem moves from left to right you will have the problem in your speaker or its cable-if not the problem in your receiver itself.
you can apply contact cleaner in volume control and move it forward and backward and test.

SOURCE: no audio output

Were you playing it very loudly when it died?

The manual is here for reference...

http://www.docs.sony.com/reflib/docget.asp?manualid=11654&template_id=1&region_id=1&DL=',600,560,10,10,'Manuals'

It discusses troubleshooting this problem on page 50.

When you turn the receiver ON does you hear a light click in about 5 seconds? That would be the protection circuitry turning OFF to allow the amplifiers to function. The delay is to allow the circuitry to stabilize before it sends any output to the speakers. If you don't hear a click the unit is Protecting the speakers due to malfunction somewhere.

If no click and no apparent messages try turning the speakers OFF using the Speakers button directly below the Power button (1/0). This will eliminate or point to external shorts as the cause.


Does the unit click after 5 seconds of Power ON with the speakers OFF? Isolate your shorted speaker or wire problem.


Still no sound at the speakers when you turn them ON?

We need to establish if there is any programming flowing through the receiver.

A quick basic check would be to tune an FM station, if you have a tape deck attached, place it in Record or Record/Pause mode so it can display the input signal levels. You should see the record meters fluctuating with the level of the program selected. If you don’t have a tape deck, run an RCA cable pair from the audio output for a tape deck to an analog audio input on your TV. Select that input on the TV and you should hear the FM station, or anything the receiver is configured to play. If it's silent then there is no audio signal circulating in the receiver to get out to the amplifiers.

If you hear the program on the TV but not through any attached speakers, then the amplifiers are all disabled for some reason.

If there is no audio flowing through the receiver the problem could be a switch in the wrong position, source not selected, muting on or a multitude of other things.

Let me know how this turns out.

Again...how do you hook up these 3 items...i have no manual...a Pioneer stereo tuner control, power amplifier, double cassette deck, and speaker...pioneer model #CX-770, CT - W 770, & M - 770?


This would be easier to help you with pictures but I will give you the basics. There should be an input that is labeled either cassette deck or line in. That is where you will plug in the cassette player (that is coming from the output of the player) The cords should be red and white for left and right audio. The back of the tuner should have an output labeled something like preamp out. That will be any number of types of connectors but you should be able to find the right cables. From that output put that in the left/right channel of the amp. It may be labeled something like channel 1 channel 2 input. The speakers will go to the output to the speakers probably also labeled channel 1 and 2. If you post pictures of the backs of all of the equipment I will get more detailed.

Conncet a sony sub to a denon reciver


Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

I HAVE NO CABLE BETWEEN TUNER AND AMPLIFIER


Normally you should have a stereo "line" connection. The cable consists of a pair of "RCA male connectors" on each end of the cable, "RCA" is the style of the connectors, usually one red and one black or white on each end.. "Line" refers to the type signal and voltage level of the signal. The tuner should have a pair of output jacks labeled as such and also labeled Right and Left. The power amp should have similar jacks labeled "tuner input" or "tape in", "phono in" etc. don't use phono or "mic in" if that is a choice. Use tuner in or tape in. Connect the same colors to the same channel on each unit, ie, red to right and black to left on each unit. On the amp you may have the option to select the input source. Select the one you are using for the tuner. Turn on the tuner and the amp and listen. Good Luck.

Some DVD's sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it?


" Some DVD\'s sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it? "
Hi,
I wrote a short article for someone who had a similar problem a few days ago.
I will edit it for you so that it fits. Here it is.
Your DVD player should have output connectors in the back of it to plug your amplifier or receiver into. If you have a Stereo system (no surround sound speakers, or front center speaker) connect the DVD Audio Cables on the back of the DVD player to the STEREO (or MIXED ) Output Jacks. If it is connected to the Left Front and Right Front jacks of the "Surround Sound" output jacks instead of Stereo(or MIXED) then the dialog will be sent to the CENTER channel output. If you have no center channel speaker you will not hear it. Thus no dialog.
NOTE: In your case for the TV that is mono, here is the solution.
1 Connect a stereo pair of RCA cables (red and white "male" connectors at each end) to the Mixed or Stereo Output of the DVD player (NOT ANY SURROUND OUTPUTS).
2 Purchase an RCA type "Y" connector that has 2 female to a single male connectors on it. Walmart about 3 dollars.
3 Plug the single male plug of the Y connector into the back of the TV set's single mono audio input.
4 Connect the stereo RCA pair from the MIXED output of the DVD player into the Y connector that is now on the back of yourTV.
5 Run your yellow Video output from the DVD into the Back of the Set's yellow input.
That should do it. The sound should be clear and correct with dialog, effects and music.
Hope this helps,
Best,
Mark

Is this receiver capable of speaker signal output to "A pair" AND "B pair" AND subwoofer AND center channel simultaneously? How do I program that? Can this receiver be used as a pre-amp for switching...


According to the manual, which you should have:

1st question: No "A" and "B" choice, just one set of Front speakers. Center speaker, yes. It requires a self-amplified subwoofer.

2nd question: In the manual. Select Speaker Sizes, presence, distances and other parameters. Run Test Tone for relative volume of each.

3rd question: Yes, for stereo material only. It has no multichannel Line Level pre-outs.

Only get sound out of right side both a and b


Good day sir, Hi, your Philips receiver trouble can be any of the ff:
  1. your receiver left fuse is blown, check if it has a user fuse at the back. or
  2. your main IC amplifier for the left channel is bad. you need to replace that IC, but check first the wiring of the speakers.
  3. Check your receiver left speakers if it is producing a soft hum, to do this turn down the right channel, or adjusting the balance knob to the left, or simply remove the speaker connection of the right channel. place your ears on the left speaker as you adjust the volume up and down, do you hear a soft hum that goes up and down also? If yes the problem is on the source section before main amplification, usually the pre-amplifier stage, If you hear no hum at all. problem with the main left amplifier. The main amplifier is usually a single IC for both left and right channel, OR one IC amplifier for the left and one for the right, in both cases, replace the bad IC.

I have a Fisher RS-717 stereo receiver, amplifier. The speaker connections are channel A left & right and channel B left & right. The question is, can you connect speakers to just one channel...


Yes you can use either A or B without a problem. The restriction is when you have both A & B connected. In that case, the speakers MUST be a minimum of 8 Ohm impedence. Using either A or B, you can use speakers of 4 Ohms impedence.

1 channel w/ intermitent cracking & popping


If it happens more when it warms up, It probably needs two transistors on the amp board. not the main output transistors but the pre driver ones.

How do I hook up a fisher stereo to my tv so I can here the sound from my tv on my stereo speakers?


You have to have audio outputs on either your TV or VCR/DVD to input into your stereo. Look for the red and white RCA connectors. Most TV's have RCA inputs for audio and video but not always outputs. VCR/DVD players all have audio out so if you have one of these units connect a RCA cable to a input of your Fisher amp. I hope this helps

I need to set up 4 pair of speakers, two zones. all ceiling mounted.


Okay! all ceiling mounted speakers. I don't know about 4 pair of speakers.Here is the load down:
First pair of ceiling speakers would be left and right front from speaker A or Main output behind your receiver.
Second ONE,but a pair would be connect to the center channel output as your center speaker.
Another pair would be connect to the surround sound left and right(NOT surround BACK left/right.)
Now,you have 5 channel setup at this point,you still need to purchase a power subwoofer to the SUB PRE-OUTPUT behind your Denon receiver.

For Zone two,you would need to connect your other pair of speakers to surround BACK left and right output.
Go to your Denon MENU button,depending on which model you have,some of them will have an on-screen display feature(you would need to have a composite video cable connect from the video output behind your receiver to the TV video input in order to use the on screen menu.)If not,you would have to it view on the front panel of the A/V receiver.
You need to read the detail on how to setup the video and audio as well as distance and DB for the receiver through the menu button.
I will be frank with you,if you are an amateur,Denon is NOT easy to be setup on the first time.
