I have a tivoli PAL. I turn it on, sound is normal for a minute then loud popping, volume jumps up and a loud staccato popping stays with the audio. I turn it off and on and it's ok for seconds then the popping, loud volume and loud booming distorting fluttering staticy interference kind of pattern sets in. Any help appreciated.

    Well, I will sort of solve my own problem. After searching it seemed to be the volume potentiometer. Not pretty but I pryed the metal casings off the pot and the mode switch, loosed the horizontal board and put a few drops of electrical conductivity enhancing fluid into the volume potentiometer. Put it all back together and it seemed improved for 10 or 15 minutes and popping resumed. Let it sit for a day, turned it on and now it works fine for hours with no popping. I think the fluid may have needed to appropriately evaporate. Good luck.

I have the same problem with mine. Contacted TIvoli and they said this is a unique problem. I believe it's a common defect related to the AM/FM switch though. Please contact Tivoli. Maybe if enough folks report the problem, they'll consider doing the repair out of the 1-year warranty. Let me know how it goes.

SOURCE: Tivoli Model one radio - volume control does not

I noticed the same problem after I had moved. Hadn't had it before. The solution was easy in my case. (It took some time to accidentally figure it out though). I flipped the power cable around 180 degrees / upside down and re-connected. After this the volume worked as before. This was the model with European power plug.

What could be causing a loud popping when volume is raised past a certain point?
This is normally cuased when customers rely on small amp in any radio instead of an aftermarket amp. If your radio starts to clip wither lower to normal listening volume or invest in a aftermarket amp to amplify sound.

Tivoli PAL volume problems
I posted this tip elsewhere but the FixYa site is, shall we say, challenging.<br /> After years of use my Tivoli PAL started having volume problems. The audio began popping, volume changed erratically, static, booming, almost feedback sounds.<br /> In my case, and others as well, I've gleaned, the problem was the volume potentiometer. Apparently it oxidizes over time and the poor electrical contact is the reason for the erractic audio.<br /> I'm not an electrical repair kind of guy, so this isn't pretty.<br /> The volume and frequency controllers are secured to the knobs with metal collars. I pried the collars loose and got the horizontal board off, I sprayed Stabilant 22 into the volume pot. There are other electrical contact cleaners as well.<br /> Put it all back together. Let the flud dry. Good as new.<br /> Good luck.

My father has a Dynex LCD TV, Model DX-37L130A11 Rev A, sticker says 10H07-Rev A. Manufactured August 2010, Lot #: 205204 XHT 100453. A few days ago he said the audio started emitting a loud, cracking...
It sounds like you've done quite a bit of troubleshooting, which I applaud you for doing. Have you tried power cycling the TV? Simply turn off the TV, unplug it (and any components connected to it), then plug it back in and turn it on after a minute. See if this corrects the issue. If it doesn't, then I would recommend calling our Product Support team to schedule repairs at:
U.S., Canada, & Puerto Rico - 1-800-305-2204
Mexico - 1-888-882-7326
daily from 7 am - 12 am CT.

Sound on Bauhn tablet no longer working
Go into the settings for the Bauhn tablet and reset the sound volumes. This also happens when you plug in the HDMI. Otherwise you can back up your files, then flash with a custom ROM to the tablet to get your sound back again. Updates to the ROM should correct the scratchy sound and stop the silent mode problem.

My Tivoli Model One makes a loud screech/buzz noise
I had the same problem and was able to repair it quite easily. Only thing needed is some basic soldering skills.

Problem description:

  • Suddenly a quite loud and disturbing (scratch/screech/buzz) noise appears.
  • Sometimes the noise is gone but it reappears sooner or later.
  • Changing volume or radio band / input (am, fm, aux) does not affect the noise (even on volume turned down all the way).
  • The signal coming out of the Headphones / Rec Out plug is not affected.

Cause:

  • Cold solder joints

Solution:

  • Unplug from mains
  • Remove back panel (the two black screws next to the plugs in the center). The back panel sticks quite firmly, so it might help to remove the front panel first (the 4 screws in the corners) and carefully press out the back panel from the inside. (The other two (silver) screws are used to attach the transformer to the back panel) and need not to be loosened.)
  • On the circuit board at the back panel locate the plug that goes to the speaker (is says "J2"). Check the solder joints. In my case, looking closely, I could see that they're not good anymore.
  • Renew the joints by heating them up and applying some fresh soldering tin. I also renewd the joint from the wire bridge next to the plug. Just check the other solder joints on the board.

In my case afterwards the problem was gone and the device is working properly again.

Tivoli Model one radio - volume control does not go to quiet. I like to listen at night but volume does not lessen past a certain point which is too loud.
I noticed the same problem after I had moved. Hadn't had it before. The solution was easy in my case. (It took some time to accidentally figure it out though). I flipped the power cable around 180 degrees / upside down and re-connected. After this the volume worked as before. This was the model with European power plug.

Tivoli Radio,
Does your radio have a sleep button or option? If so, check to make sure that you did not set it on accident or with out knowing. Or if it has batteries, check them to make sure they aren't dead or mixed with old or new.

Poping in speakers
Same issue with my AVR-589...2-15 minutes after sound is playing (via TV or DVD). I checked all wires and speakers. Even reconfigured to audio only (analog) coming in, same issue. Put my old Denon receiver in and the problem disappears...possible overheating issue with this new unit?
