Try make sure all cables are fully PLUGGED in... inserted all the way

Hi, I was able to fix my set by changing only three out of the six capacitors between the heat sinks opposite the plug on the board. I noticed under a microscope the caps looked a little puffy, but not much, and I checked them with a capacitance meter, but they were in tolerance, but decided to change the three closes to the edge of the board with a 1000uf, 50v, 1000uf 25v and 1000uf, 50v with the one that is 25v going in the middle, I didn't have another 1000uf,50v for the middle one. (sometimes you gotta use what you got to get what you want) So I powered my set up and it stays on . I hope this helps. I may go back and replace all six with 1000uf, 50v, but the space in there is limited and those are some large caps. I will wait until the set acts up again before i do that. I am satisfied with it for now. Again I hope this will help with what you've got going on with yours.

Should it be a power supply that outputs AC and converts to DC inside the speaker case, or is it a wall adapter the outputs DC straight to the built in amplifier?Some speakers have the voltage and polarity for the plug on the back of the speaker where the power lead plugs in. As they are only small speakers of probably a couple of watts it may only need about 2 Amps or less. Higher current is fine as the amp will only use what it needs to work correctly but I would'nt go below 2 Amps.

This type of audio feedback loop can happen on any mic if you are playing back audio at a loud volume on speakers that are close to the mic while the mic is on - which tends to happen on Skype calls. Try lowering your speaker volume or using headphones to hear the audio, then speak into mic, and the feedback should be reduced.

If this is a microphone that connects to the 3.5 mm microphone jack, check that your microphone is connected to the Mic port (pink on the rear of a desktop). Make sure that the plug is fully seated. If you are using a front microphone jack on a desktop, try using the rear port (or vice versa). Next, if you have Windows, check that the audio input is set to Microphone, instead of Line In. (For Windows 7, this would be Start > Control Panel > Hardware and Sound > Manage Audio Devices (under Sound) and the recording tab.) Microphone should be your default device. Next try uninstalling the audio driver and letting Windows reinstall the driver. Use the Device Manager (under Devices and Printers in the Hardware and Sound Control Panel). Expand the section labeled Sound, video and game controllers. Then right click on the Audio driver. Click on Uninstall then reboot the computer after the driver is removed. The correct driver should be reinstalled. (I believe that you do not have a separate driver for the microphone under Windows but you should make certain of that.) Check for driver updates as well. The Windows Update may list these as Optional updates.If you have a USB microphone, try a different port. Also check for drivers from the manufacturer. If you have an Apple or Unix OS, check for similar issues with the connection or drivers. I hope this helps. Cindy Wells (who had a similar problem with Audacity recording on the line in port last month; I fixed the problem by uninstalling the audio driver and then reinstalling it. Then changing the Recording Source to Line In finished the fix. The driver got changed by a computer tune-up utility (registry cleaner).)

Open up your computer the speakers plug/outlet is usually at the back of the computer

to check the lead attached to the rear of the input plug make sure the connection is good

or you might have to clean the dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems

hope this helps you
