Dx8100 wont power up

your power supply is overloaded, check the power supply of your phone

If your power indicator isn't lighting up, you don't have your 5vdc standby power. You're most likely looking at a power supply issue. Did this happen after a T-storm???

check the capacitors in the power supply. If the top is bulging up, they are bad. Just replace them. You can get most caps from Radio Shack.

You may have a motherboard problem - check the BIOS battery first and then re-seat the CPU and RAMs.

First thing I would check is the power supply, easiest way to test it is to just swap the power supply with a working one.

That's easier said than done if you're just an average user so unless you've got an extra power supply handy then I would suggest finding a local computer repair shop that provides FREE DIAGNOSTICS, most do these days. Have them check out the system. It's either the power supply or motherboard. HOPEFULLY it's just the power supply though ;)

If the repair shop says it is the power supply I'd sincerely thank them for their time (5 minutes) and then I'd buy a replacement power supply and install myself ($15-25)

Hope this info helps!

usually a bad power supply behaves this way.

You might want to swap the power supply for a used one or perhaps take it in for a checkup. Shouldnt be too costly. And then you can either replace the parts yourself or have the service persons do it for you.

if it sparked then something inside the power supply malfunctioned and that is the reason it wont work. You will need to replace it. Unlikely that it fried your board in the process. You can test this by swapping the power supply with one that you know works.

check first your power supply output voltage by multimeter set to DC. output: 3.3VDC, 5VDC, & 12VDC before you swap.

Contact the manufacturer at (800)289-9100 x 2781 for instructions on how to reformat the drive.

The power supply is defective if your TV is one year old or more. Unfortunately there aren't any service parts available to swap the power supply module. The only option at this time will be to get the power supply repair.
I service these power supplies.
