Question about Sony DAV-S500 System

2 Answers

Turning off I have only one problem with this system and that every now and then it goes into what appears headphone mode without any headphones being plugged in, and then at some point the sound returns as if nothing has happened.

I got a DAV system that had exactly the same problem, ie. it was stuck in "headphone mode", this mode should be active when headphones are attached then it should revert to amplifier mode when the headphones are removed.
I opened the cover and removed the amplifier output board (the one where the speaker wires connect to) and soldered the following dry joints.
1) large brown capacitor on the amp output board.
2) dry joints on the rear headphone socket (the one that has the connecting lead from the front headphone socket)
3) Then one of the surround channels didn't work so I soldered further dry joints on all the coils (white vertical rectangular blocks)
I tested all surround chanels before putting the lid back on (careful, watch the mains) and found all was now working ok.

I plug my iPad into to headphone jack but I don't know how to get it to work


The headphone jack on the shelf system is for connecting headphones. It is not an input for sound from an iPad or other source.

Buy a lead with headphone jack to red and white RCA/phono. Jack goes to iPad. Red and white goes to Game Port Audio in (bottom edge of unit). Select the GAME input. Play your music.

Headphones are a convenient way to experience audio-rich entertainment on your own terms. Headphones allow you to customize your listening level without disturbing other people in your general vicinity. Headphone cables can be a hassle, however, so many new headphone models feature a wireless connection. PCs tend to be wire jungles, so eliminating one wire from a potentially jumbled mess can be an intriguing feature of wireless headphones. Connecting wireless headphones to your PC allows you to take advantage of the benefits of listening to your movies, music or games through headphones without the struggle of the headphone cable.

Charge up or place batteries in your headphones and transmitter. Wireless headphones require power to function. Many wireless headphones come with a charger base. You need to charge your headphones before you attempt to connect them to your PC. Some wireless headphone models require batteries, which you must install before you connect the headphones to the PC. Connect the transmitter to your PC. The transmitter may connect via the PC's headphone jack or USB port. If the transmitter connects to the headphone jack, plug it in and check your headphone's user guide to verify how to synchronize the headphones to the transmitter. If the transmitter connects via USB, you will likely need to install software to use your wireless headphones. If your wireless headphones are Bluetooth-compatible, continue to the next step. Pair your headphones via Bluetooth to your PC. If your PC is not Bluetooth-equipped, you will need to install a Bluetooth USB dongle. Turn on your headphones and open the Bluetooth software on your PC. Scan for Bluetooth devices from your PC. Your headphones should appear. Select the headphones and follow any further instructions to complete the pairing process. Test the headphones. Pick out a song or a video and play it on your PC. Connect your wireless headphones and verify that you can hear the audio. Find the volume controls on your headphones and adjust them to make sure the volume changes correctly. If your headphones are not functioning properly, verify that the headphones are turned on. If the headphones are on and you do not hear anything, verify that your transmitter is functioning properly and that you have your volume turned up on your PC. Recharge your headphones when you are finished using them. To ensure that the headphones are ready anytime you need them, you must always place them on the charging base when you are finished using them. If the headphones are battery-powered, be sure that you always have spare batteries on hand. Hope this helps.

Hello! I have a sound problem. When I us my headphones and plug them out my speakers won't sound. After a few restarts the speakers will come back to life, but if I plug in the headphones and plud them...


This is a setting issue ..and it is from the audio driver..When you plug the headphones it is normal to cut out the general sound..and work only on the headphones..But in the moment you unplug them a window should appear to ask you to select the 2 speaker out or laptop mode..
If this do not appear it means some changes were made in the settings of the sound manager and this is the cause ..basically you force it to headphone mode...but after a few restarts it sees the there is no jack plugged and ask for the normal mode again or takes it automatically ..Try to reinstall the audio driver ..this should fix any issues related with it ..If the thing goes on ..it may be the case of a damaged plug on the headphones out-let ..basically does not detects the jack being unplugged ..and you have to see whats wrong ..or change the plug if you think its necessary ..Or just plug and unplug a few times when you remove it ..maybe the contact its poor ..and does not sense the action being done ..
if you do not have the driver see this one

Cant get the pulsar 590 works with windows 7


I finally solved this problem. Buy a CSR v4.0 enabled bluetooth dongle on ebay, plug it in to a usb slot. Right click the bluetooth icon in system tray and select "Settings" and tick "Allow bluetooth devices to find this computer." Then click "add a device", turn on your bluetooth headphones and the headphones will show up in bluetooth devices. Add the device, then right click your speaker icon in the system tray, select playback devices. From the menu, select the headphones and set them as default. I did this and they work perfectly. Furthermore when I turn the headphones off, the sound goes back to normal speakers - no other adjustments made. Turn the headphones on again and the sound defaults to them. I noticed on an earlier failed install of the headphones when they did appear in Devices and Printers that the drivers were CSR something enabled. I did try some cheaper dongles and the actual Plantronics USB dongle(expensive) to no avail. Get a CSR 4.0 enabled device. Mine cost 6.00AU total.a199a342-df05-4c7a-89f7-c82a948f31c9.jpg

My sony dav-s-400 system keeps activating headphone port output.


Just had and fixed the same problem that hundreds of people are suffering with this system!!
Sony DAV s400 - same problem, won't play though speakers and display indicates that headphones are plugged in - when they are not. Fairly easy to fix and took me less than an hour from start to finish:
1) Remove top cover
2) Remove circuit board that has Audio In/Out phono scockets (to get access to Amplifier Circuit Board)
3) Remove Amplifier circuit board (has the speakers attached)
4) Turn it over and remove copper heat shield
5) Resolder joints where the big brown capacitor is and where the wires go to the front headphone socket...and any other dodgy joints that you find
6) Reassemble.
