We were listening to music , cd , & a buzzing sound came over sound system then nothing. no functions work at all. Main board lights up but that is it.
Re: We were listening to music , cd , & a buzzing sound...
If the screen lights up then shuts down this could mean it's going into safe mode the other option is that part of the power supply could of failed this is normally only a capacitor or resistor

Main power regulator board or back light inverter board can be the cause to this buzzing noise. Contact any service technician to troubleshoot. http://electronicshelponline.blogspot.com/
Hook a charger up overnight, or try the jumper cables again. Make sure they are connected to the matching terminals. Check to see if anything has power without starting the car. Lights or radio working with key in the ACC position? If not, something has killed power from the battery- maybe a main fuse or a power distribution relay. Make sure the cables/connections aren't corroded at the battery posts.
Main control board located in white plastic enclosure at rear bottom of unit is bad, a burnt tracing on the board plus a few board component issues. Buzzing noise is from a confused relay. A Whirlpool product issue??? This appears to be a common problem and is discussed in several different forums. Implemented and "no cost" work around as detailed in one of the forums. Unit appears to function properly after repair/re-work.
1st of all
click on start->programs-> Accessories->Entertainment->Volume control->options->properties->select Microphone->then click on Mute on microphone.
hope this will work
I've had the same problem and I think I've solved the problem. I noticed that they were fine when I first turned them on. After a awhile the blue light would flicker and static would start. I figured there might be some connection so I unplugged my speakers, took off the thin rubber from bottom and removed the 3 small screws. I carefully pulled the circuit board down, spotted the led light and snipped it off. I put everything back together, double stick taped the rubber piece back on, plugged it back in and have been listening static free for hours. Yippee, no more room full of screaming babies (that's what static sounds like to me)! By the way, I'm no expert. I just have a very strong aversion to static. Good luck, Beth
You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25. I would replace all 6 on your system. To insure that the other's do not go bad after fixing the bad ones.
There are some repair instructions available at www.AnyoneCanFixIt.com in the electronics section that will show you how to release the CD magazine and fix the problem where the unit will not play the CDs (you will hear a buzzing, buzzing, buzzing, and nothing will load or play).
Sorry pal. Machine is a DELL Inspiron 1721. No cable neither loudspeakers. I have no motherboard CD shipped with laptop. I already tried to install audio drivers from DELL Utilities & Drivers CD, but OS refuses to recognize that a soundcard is present.
Thanks anyway. It has to be solved by someone who's had the same problem and managed to work around it.
