As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will proibably last forever now.

If my pc wont turn on with the cable plugged in, what's wrong?


Check whether power pack has output voltage. If not, power pack is faulty. Replace it. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box.

My computer will not start up, the LED light on the power unit will not come on. It was working fine. I shut it down so that i could connect it to my TV when i plugged it back in...nothing...please help...


Look on the back of your PC. Is there a switch with a I and O on it? Flip it to O and back to I and try to turn your power back on.
If you are plugged into a power strip you may want to try cycling the power on the strip as well.

Its pluged in but there is no power at all, sound red light nothing. Whats wrong with this thing?


it seems you have a power supply problem here, if you dont have any lights or at least the red light when you plug it in, it may be your power supply is shot. they are not so expensive but you need to search auctions and used electronic parts sites for the power supply. replacing it may solve your issue if you want to be sure you may want to get a service manual download in pdf format this may help you trouble shoot your problem.. hope this helps..

I push the on button and nothing happens. is it


Hello,

Even though a lot of things might have gone wrong and caused this, especially if where you place the System is not well ventilated, and the CPU becomes very hot, it shuts down automatically...and you will have to wait for a few moments, get a cool environment and power it on. but I will also try and tell you some troubleshooting steps that you can try.

Since you have already checked the power source and all is Ok, then try this out:

Disconnect your PowerPack(Power Supply Unit) from the CPU and try to power your PC with another Power Pack (Power Supply Unit), that you are very sure is working.

If it powers up, then just get a new Power Pack(Power Supply Unit) for system.

If you cant do this yourself, just get a good technician to do it for you.

Try this first and let me know how it goes, so as to know the next step.

Hope this helps.
Goodluck!

My hp desktop computer will not turn on


If you cant see or heard any boot up sounds, fans and especially if you dont see any power or green led lights at all ;

If your power cord is plugged into a power strip or surge protector, power cycle your strip or surge protector by turning off and on.

If power outlet has a wall switch make sure its on

Check that your power cable is securely plug in to both ends

Check that at the back of computer, specifically on the back of the power supply unit that the switch is on "1" position and NOT on the "0" position ( 1 is "ON" , 0 is "OFF" )

Check that the power outlet is not damaged by pluging in another good known device (such as a blowdryer, shaver, lamp, radio, etc, etc) to see if its the power outlet or not.

Can you see power or green led lights and hear the fan on but no display ? If this is the case , check your monitor connection at both ends. If they are secured open up your case and see if you can smell any burnt smell or check that all cards especially video cards are properly seated.

It sounds like you have a power or an interference issue if it occurs at the same time every day.

I would try plugging it into a regulated power source, a UPS if possible or at least a power strip.

If it is in a power strip, I would swap the power strip. If it continues to happen at the exact same time every day, I'd also try plugging it into a different area of the house and watch it at the "bad" time and see if it still happens.
