I went away on vacation, while I was away there was some maintenance work being done on my building. They cut the power to part of the building, which turned off my computer and basically all my electronics. My speakers did not turn back on after this. Everything else is fine.
The speakers were connected to a powerstrip/surge protector. I tried connecting the speakers to a different power outlet, I tried using a different power cable, I checked the fuse it was fine, I even tried bridging the fuse spot but still no response. I pulled out the internals and looked for burned components, everything appears fine. No cracked IC's, no burnt resistors, no popped capacitors, no sign of anything wrong. The power light does not come on at all so I assume the problem is somewhere within the internal power IC's, but not really sure. I opened the wired remote controller and that seemed fine as well.
The only response I got was a little bit of sparks when I bridged the fuse spot with a screwdriver, and the sparks stopped when I switched the power switch to off.
Any suggestions? Creative wants $375 to fix it, the system costs $430... yeeaaaAAaaaahh they really make it worth it to get it fixed? Ugh...

Check the power adapter for continuity. If you experienced a power outage or surge lately, the adapter and/or camera may be damaged. Try to use camera with alternative adapters of the same voltage/current/.
Vizio TV model E371VL turned on ok and had tv show on ch.4.
Turned on the DVD player and put movie dvd in and closed tray.
We have done thhis numerous of times and never had a problem.
This time " HDMI " was showing on top right of black screen,
then " No Signal " came up on screen, then went completely black screen. Called Vizio, they had me power off and unplug set.
Push and Hold power button on TV for 30 sec. to reset.
Replug set and Vizio (lighted) on lower front of set lighted normally dull orange. Pushed power button on remote and when set did not come on, then push main power button on side of TV. Nothing, no White " Vizio " from orange light. Is this a power supply (0500-0412-1020) problem ? Thanks, Sidney (email@example.com)
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 or you might have to clean
the dust from your computer dust causes static which causes your computer to
overheat and all sorts of problems be sure to wear an anti
static earth strap before touching anything inside your computer 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 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
Chances are that either the soundcard or speakers on your pc have been damaged by the sudden power/surge outage.
Suggest you try youy speakers on another pc or connect to your TV to test them. If they work fine, try putting some earphones/headphones into your pc (same connector as the speakers) to see if they work there.
Either way, from the above you will be able to tell what's broken. If the soundarc on your pc is damaged, you will prob need to take to someone to see if they can fix or replace the part. They may need to replace the whole motherboard.
Is the power supply AC or DC. I had a similar problem with my boston acoustics speakers, and I was able to swap the power supply for a DC output one of the same voltage and amperage and the hum went fully away. it is an inverter circut that went bad in my woofer.
if no light came from the speakers then something is corrupted inside them .. you have to check the power source and power cable of the speakers first ... if everything is fine then the speakers are corrupted from inside
Try and plug your speakers into a friend's computer and check if they work. If they don't, then the speakers are fried, probably because of a voltage surge when the power went out. If they do work on your friend's computer then you most likely have a bad port on your computer because of the power surge.
