I have a pair of two-year old M-Audio DX-4 monitors which have an intermittant distortion problem. When I first turn on the speakers, the audio is very distorted. Both speakers are affected so the problem must be common to the powersupply. After about 5 minutes, the audio becomes cleaner but still some distortion. I noticed that prior to this problem, when I turned on the monitors I noticed a brief hum in the audio and then it disappeared. This led me to believe that one of the electrolytics may have started to go bad. Since I have repaired electronic equipment before, I decided to try and solve this problem. I removed the twelve screws which hold the back on, but still couldn't get it removed. I then removed the woofer and put a large screwdriver through to the back and pounded on it but still no luck. I came to the conclusion that the back must be glued on? Is this correct? If so, I wonder how one can get to the circuit board to check it out?
No No please dont change your circuit board its in the problem of your increasing or decreasing volume button of your woffer box please try to change the button as quickly as possible because it has been got damaged....

If this is a "new to you" TV, keep reading. If it is a brand new TV, I'd be on the phone to the store to have a replacement ready for delivery / pick up. You do not want to be repairing a TV that is 2 days old.
The first thing to do is determine if the distortion is coming from the speaker or if it is on the signal going into the speaker. Do both speakers sound distorted or only one?
You didn't include the model number of your TV, so I can't speak to specifics. Look for a terminal on the rear of the set identified as "speaker" or "external speaker". If provided, there will be one set of terminals marked for the left and one for the right external speaker.
Connect a speaker directly to the terminals marked for either the left or right speaker (connect to the one that sounds distorted if only one of the built in speakers works correctly - other wise pick either speaker terminal pair.). Speakers that have RCA plugs on them, have built in amplifiers, require batteries or or to be plugged in to an outlet should not be connected here.
Alternatively, you could connect a pair of stereo headphones or earplugs if your TV offers a jack for them. It would have a headphone icon or say "phones" above the jack if one is provided.
Once connected, turn the TV on, lower the volume and set the TV to enable the external speakers / disable the internal speakers. This may be done via menu item selection or a small switch near the speaker terminals. Slowly increase the volume to listen to the quality or clarity of the sound coming from the speakers you connected. If they sound distorted, the problem lies with the audio amplifier in the TV. If they sound OK, then there is a problem with the speakers in the TV.
If you can't return the TV, you may have to see about using the left and right audio line out or HDMI jacks to send the audio to an external amplifier and speakers to hear the program.
I hope this was helpful and good luck! Please rate my reply. Thank you.
if your computer came with a motherboard disc the sound drivers could be on it you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling a yellow? question mark means you need to install/update driver to do this right click to install driver also click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have the correct settingsthere also click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar if his does not fix the problem
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer hope this helps
