Just hear slow pumping sound when power is on.

Whether or not ipod is docked...power on yields only slow drum-like pumping sound.

I popped it open and it seems to behave when its not closed. Seems the culprit is the chip that reads ON 317MBG near the chips w/ the heatsink. I put the cover on loosely got the popping to start again. I hit it with compressed air and it stopped. I'm going to either put some thermally conductive epoxy or silicon to draw the heat away from the area or put wires on that the component to locate it elsewhere so it doesn't get that hot. The component is rated for 125 C

My M602 does the same thing -- I couldn't find any posted solutions anywhere, and no schematics to try and fix myself.

I just got off the phone with Altec Lansing (800-258-3288) - they said this was an internal circuit problem.

They gave me a return number and address, saying they would repair/replace the unit at no charge. No hassles -- didn't ask for anything other than my name and address for their records.

We'll see how this all turns out. Hopefully my only cost will be the shipping charge to PA.

Hi.. I have a bose wave ipod docking system.. the sound is amazing.. or was... until a few weeks back when i noticed that in order to hear my ipod... i had to tweak the ipod a little on the docking...


Are you using a voltage adapter of some kind to convert the ireland standard 220VAC to the USA standard 120VAC that this device uses? Over voltage can deplete an electronics life very quickly.
By the sound of the "thump-thump-thump" noise emitting from the device, you may have a broken ipod dock connector, or a short somewhere in the connector/wiring/device itself, or the ground has failed.
By the description of having to "tweak" your ipod to hear it, it sounds like you've slowly broken the dock connector. Check to see if it moves easily, or if you can hear anything loose.
This is more than likely fixable, but it's probably easier to replace the device than to fix a broken connector.

Broken connecter that connects 2 iPod on the dock


From your description, it's not clear whether the broken part is on the iPod or on the dock.

If the broken part is on the iPod, then it might be least expensive to buy a new iPod,
depending, of course, on which iPod (Classic, Nano, Touch) you own, and the value of your iPod.

If the broken part is on the dock, then you'll have to replace the dock.

I have a denon ipod dock and a harman/kardon receiver. Can I connect the dock to the receiver?


To plug the dock into the receiver to supply power and interface with the iPod you would have to have one with a built in iPod. Most receivers will not do that, the most common way to connect an iPod to a receiver is using a 3.5mm to RCA cable. You don't even need the dock to do this, you can plug the iPod directly in. You can find this cable at most electronics shops if you don't want to buy online, like Best Buy or Radioshack.
Make sure you connect the white and the red end of the RCA cable to the correct sockets on your receiver, and the small 3.5mm jack into the iPod or the iPod dock, you have to turn the iPod volume up and select the corresponding input on your receiver. If you plugged the 2 RCA jacks (white & red) into the socket labeled "AUX" or "Video 1" you have to select "AUX" or "Video 1" in order to hear the sound.

ILive Bar Speaker not playing sound


I have an iLive bar speaker ipod dock and it has worked great until today. The sound isn't working. You can hear that it is on, but it isn't playing music. The display works and everything. Is this fixable?

I pod charges, plays, but no sound


Easy, I had this problem too. The reason it isn't playing is because its not in all the way. I was getting very frustrated with this, so I kept trying to push it onto the dock to get it all the way down.
Solution:
1. Play a song on your ipod/iphone so you can hear it through the device.
2. Connect your ipod/iphone to the docking station(Bose) so that you hear the chime(This lets you know its charging).
3. Pick up the docking station and firmly press the ipod/iphone down on the connector.
4. Keep pressing it and wiggling around until you hear the music begin to play through the docking station.
It may take a few tries, but you will get it.
Hope this helped!

Bose sound dock - no sound comes through it but my ipod works with the ear plugs so it's not my ipod


I had this problem for the pat two days. Believe it or not I took my Ipod touch of the dock. Shut the power off to the Ipod to reset it. Also the power to the docking station. turned everything back on. Put the Ipod back into the docking station and heard the beep.. and hit play and it was working again. Not sure but shutting Ipod off does act like a reset.

Wont play through my bose system anymore


the apple ipod are very delicate and it seems that docks are very harsh on the internal workings IE: motherboard of the ipod. it not just the touch, it's all ipods.
My suggestion is to check the headphone jack and if you get sound, don;t play your ipod on the dock at all. Your dock has probably done some damage to the audio circuit on the board.
If you get sound through the headphone jack save your ipods life and just use it through the jack.
I have replaced numerous motherboards on ipods played on docks. they just don;t handle the charging and playing very well whether it's heat or just the wrong voltage I am not sure.
But my first question to a customer is have you played it on a dock.
I would stay away from the dock

Bose Ipod docking station not working!


Make sure the power supply is connected properly. If the power supply is connected upside down or sideways, the system will make a thumping noise, or will not play at all. However, no damage will be caused by connecting this wire incorrectly.

I had the same problem but with a different TEAC docking product.
My TEAC would not recognize my ipod therefore I was unable to control my ipod via the docking station remote control.
Plug your ipod into the docking station and power down (reboot) your ipod. Once the ipod powers down (in the dock) restart the ipod (yes, while in the dock).

Ipod dock plugged it, switch to DMPORT no sound from speakers


I had the same problem. I tried everything and finally following two fixed the problem:

Dock insert has to be put before inserting Ipod in the dock. Dock insert usually comes with iPod when you buy it....After inserting the doc I was able to hear the sound but it was very faint. Then I updated the ipod's firmware. My Ipod classic was two years old. I updated the firmware by connecting it to the PC and opening itunes. Clicked on 'ipod' link and clicked to update button.

After the update, this ipod started working with my home theater system's DMPort.

HTH.
