Question about Harman Kardon AVR 235 Receiver

Sound is There Then its Gone!

The Sound just stopped, power is still on, Tried analog inputs ; no go. I have the main display but also the OSD menu does not come on to the TV, it displays on the RCVR display but have no idea where it is in the menu! tried the TEST for audio channels it is working on the display but no sound. Thought it was a fuse so I opened the cover and checked the obvious ones...there ok!. There is also a fan inside and when the power is on it does not seem to operate. I have not tried it outside the unit yet. Anyone have the schematics for it? Then I would be able to troubleshoot it! Was it just the end of its existence! I sure don't want to take it to Radio Shack @ $500/hour!!! Any assistance will be greatly appreciated!! Thanks

You will need to trouble shoot the audio output amp section. It sounds like the unit is in a shut down or a protection mode. Good Luck

My AVR1550 got power up with no sound at all. pls help. What should I check first.

First thing to check is the speaker A/B switch on the front of the receiver. Generally a small button on the receiver. You will see A/B on the LCD display. Next, check your input selection for audio. This will be on the main setup menu. Choices should be Coax, Digital, Analog and Auto. Auto is the easiest. if you still have an issue,post a comment and I will help you dig further. Hope this helps

No sound when connecting optical cable from set top box to #4 optical input for cable tv on rear. The cable only works from the front input or the dvd input on the rear but that limits my sound fields. I...

Make sure your "Input Select" "Audio" portion of the main menu is set to "Auto" you may have it in analog thus only allowing audio from the front analog input. Also check your digital input select option as well. you may have it assigned to another source input. Go into the main menu of the receiver and you will find all the settings. Hope this helps. If you still have issues, post a comment and I can help you troubleshoot further.

How do I get the " OSD" to work!

Make sure that you are selecting the correct input on the TV for which input you are plugging the receiver into. Then press the OSD button on the receiver remote. If that doesn't work, try plugging the S video into a different video input, or use a different video input cable such as from the composite connection of the monitor out. Some reasons for having to do it this way is that some televisions may give priority to one input of identical type which is usually S video. For example if you are using the S video input on the front of the TV with a different device and then plug another S video cable to another input elsewhere on the TV, it may only display the picture through the S video on one input because it is using the same circuitry for both S video inputs and can't display picture from both of them simultaneously nor can you toggle between them even if the other device is not turned on. HOWEVER, there MAY be a way around this as well...try your picture-in-picture (PIP) and toggle to the PIP input that your receiver is plugged into. Still then if that doesn't provide you with the OSD of the receiver menu, then just change one of your S video inputs to a composite input.

I used to get OSD on the TV with my receiver, but it has gone and I don't know what setting to do to get it back. It is a Pioneer VSX-917V-s/-K. Thanks

did you happen to change to cable connecting the Reciever to the TV to an HDMI?

please note that the OSD will not appear if you have connected using the HDMI output to your TV.
Use component, S-video or composite connections for system setup.

Have digital feed connected (white, red, yellow) to DVD connections 6 & 13. Get picture but no sound. Sound is OK on VID1 input from satelite. Any ideas?

so you have the yellow out from dvd player to yellow in on the receiver (composite video) and the red and white out from dvd player to red and white in on the receiver (right and left audio channel) . you can also plug in the orange rca (digital coaxial audio) go to your menu on the Haman Kardon receiver and make sure you select the right audio input. mine is a Harman Kardon AVR146 push th osd (on screen display) on the remote. go ti the input setup and select the appropriate audio input

Denon AVR-1403 receiver switched from digital to analogue.

There are three modes (Auto, DTM, and PCM) on the input mode switch, on the main unit, selected by repeatedly pressing the input mode switch.

However, if you have already depressed the Analog button in, on the main unit you have predetermined the mode as analog.

On the remote, the INPUT MODE switch combines toggles for 5 choices, [Auto, PCM, DTS, Analog,
Ext. input]

My guess is that either the input mode switch on the main unit and/or the remote are toggled to analog.

No Audio coming from DVD source

Press the input select button on front of receiver until auto is displayed it may be set for analog. Auto mode will play digital signal first then if it does not see a digital input it will check for analog signal. I would set it to auto for all inputs you may use.

No digtal audio with fiber optic jack

hook up a digital audio coaxial cable to it (not the old ones with the pin in the middle that always bends, the new one that looks like an rca cable except its orange instead of red/white/yellow). If it still doesnt play sound then your receiver is probably in analog mode. If it does play sound then its the fiber optic input.

On screen display menu

I scratched my head over this for an hour. The manual says you can access the OSD from the unit, but I see no way to do this. From the remote, you have to select the "AMP" setting at the top of the input list. Then hit the OSD button. Assuming your monitor is set up correctly, this will bring up the On Screen Display. Then hit the "Menu" button also on the remote, and you can make your adjustments. Good luck!
