Surge protectors either have a switch that trips or a fuse that blows when high current passes through. This is a safety mechanism that protects your appliances from an "electrical surge".

The fuse is most likely blown. you can easily check if the fuse still works with a multimeter. If it isnt, change it and the strip should start working again. ( if u have a reset button on the spike, try hittin that. Im not sure if this model has a fuse or the breaker switch that trips.)

Solid green or solid orange light: Your power supply is working.

Flashing orange, solid red, or no light: Your power supply may need to be replaced. Try the following solutions:

1. Try plugging your console's power supply into a different electrical outlet. Do not use a surge protector.
2. If the power supply light is solid red or flashing orange, unplug the power supply and let it cool for 30 minutes. Then, plug the power supply back into the outlet.

There is no crack or damage done to it right?
Also try plugging it into the wall dirteclty no surge or power strip and let it lay flat

Check the fuses on the power supply board first. They usually blow when you get a power surge. You may be able to replace them and get the TV running for a few dollars. If the fuses are good then the power supply board will be the issue. The main board should not be damaged because the surge has to go through the power supply board first.

Please make sure that the printer is connected to a wall outlet and not to a surge protector because surge protector distributes the total electric supply equally to each and every device connected to that surge protector. Printer might work and might not with a surge protector but it will always work fine with a wall outlet till the hardware of the printer and power chord, adapter are working fine.

some times scanner failure error comes if it is not getting enough power supply.So if it is connected to a surge protector then I will suggest you to disconnect it and connect it directly to a wall outlet.
Now scan or copy any document and see if something happens.

If not the do check while you press scan or copy button the scanner light is moving or not?
If scanner light is not moving then do a hard re-set.

Hard Re-Set :
- disconnect power chord from the back of the printer and then from wall outlet or surge protector.
- wait for 40 secondsand then connect the power adapter to wall outlet and then to the back of the printer. The try to scan or copy....still not working then check if the scanner bulb is glowing or not?

If scanner bulb is not glowing and if you dont hear any noise while you press scan or copy...then printer hardware has gone bad and you need to replace the printer

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Most likely your DC power supply input jack on the NS has cracked loose from where it's soldered onto the circuit board inside.

something burned out, has there been a thunderstorm lately?
if you get a new one, plug it into a surge protector.

Let's rule out the obvious first. It may be that a power surge has blown out the power supply on the monitor but let's check the outlet as well. Plug a lamp into the same outlet that the monitor is plugged into. If the lamp works, the monitor may have gotten zapped. If it doesn't work, plug the monitor into a known working outlet. If it turns on, the outlet is the problem. If it doesn't, your power supply may have gotten zapped in a power surge. This is assuming you don't have it all plugged into a power strip. Perchance would you be using a UPS (uninterruptable power supply)? If not, it's a good idea to purchase one for the next such occurence. You really don't need a heavy duty one. Just one that will give you about 5 minutes or so to power down after you have saved your work so nothing is lost. They also protect against such spikes and surges. Let me know what you find out.

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
