Does anyone else have a problem with using a power supply? My unit won't turn on with the power supply in.

No problem with mine. I only use it with a power supply, and it works perfectly.

Make sure the power supply you are trying to use is the proper voltage and DC output.

Something is certainly messed up. Few minutes tops.. It could be power supply..jeez... Dead Upon Arrival. I've had good luck with mine though....

You have to manually push the button on the power supply unit to start. Even you use a timer, you will still need to push the button.

The power button doesn't seem tow work on any of these units. (I have the 4 bay and have the same issue). Just log into the web-interface and shut it down from there.

I had the same issue until I realized the unit had to be plugged into a power source via the USB in order to work. Mine has worked great ever since. Have you tried that?

My bet is still a power issue. While it came with the upgraded power supply I'll bet they also added upgraded the video card. When I ordered mine I also ordered a 700w power supply.

My screen would come on briefly and go black. The 2 main capacitors for the power supply were bad. It took 15 min to unsolder old capacitors and solder new ones and works perfectly. I have the other just in case for a fraction of what I would have been charged to diagnose the problem. I would say yes if that's your problem.

Yes mine too does the same too, but when you switch off the power supply it totally goes off.

It may be a defective unit or if you added any devices (dvd drive, new video card. etc) you may need a more powerful power supply. Also make sure you are using a surge protector. I hope I am not insulting your intelligence.

Make sure the input and output are correct. If it still doesn't work then it's the power source. Try a different outlet.

Coby puts terrible power supply units in their sets, yours has probably gone bad. They need to recall this set as well I have a similar issue with it where if I let the unit fall asleep it will refuse to turn back on until I unplug it for ~30seconds, maybe try to unplug and let the capacitors drain (leave unplugged for 30-60 seconds). Good luck!

Unfortunately you have not provided enough info on your problem. In general, if it is a hardware problem, like it no longer turns on, it is not worth spending my on repairing these gadgets as it would be more money fixing them than buying a new one. If it is a configuration problem, then you can download user manual from the web or if you have backed up your unit, then reload your old configuration.

You might try unplugging the unit from the wall socket , wait a few minutes then plug it back up.

I had some problems too, until I connected the power cable to the adapter and it worked for me after that. It seemed that if you didn't use the adapter with the power cable and turned it on, it wouldn't work. Hope this would work for you.

It should be 'ok' to try. If you start getting random 'freezes' or the system just randomly 'reboots' on its own, that tells you the power supply is probably old and needs to be replaced.

I'm also in the same problem. Anyone have A home repair solution? Prior to this I had the power on problem which was solved by upgrading some blown capacitors.

I've had issues with the AC plug into the back of the unit. Try moving it around. I got it to eventually work. Happens time to time maybe a new AC adapter too?
