Where can I find replacement power cord and adpater?


what country you need to state voltage that come out of power point - is it 120 volt or 240 volt because it has to match with power supply check with seller before buying anything and definately before plugging it into a power point .
. Try amazon see http://www.amazon.com/Adapter-Supply-Charger-Dell-Printer/dp/B00L1WTFCA/ref=sr_1_fkmr3_2?ie=UTF8&qid=1404525964&sr=8-2-fkmr3&keywords=DELL+AIO+V313+ac+power+supply or search in google with Dell AIO V313 ac power supply

No power - lights no fan


  1. Verify that the power supply voltage switch is set correctly. If the input voltage for the power supply does not match the correct setting for your country, your computer may not power on at all.

  2. Check for disconnected computer power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.

  3. Perform a "lamp test" to verify power is being provided from the wall. Your computer isn't going to turn on if it's not getting power so you need to make sure that the power source is working properly.



  4. Test your power supply. At this point in your troubleshooting, it's very likely that thepower supply unit in your computer is no longer working and should be replaced. You should however test it just to be sure. There's no reason to replace a working piece of hardware when testing it is fairly easy.

    Replace your power supply if it fails your testing.

The fan turns on and off for the SL350


you might have a faulty PSU power supply unit or a faulty power point or lead
test the power point first by trying another electrical device then test the lead if these fail you will have to test the PSU using a multimeter making sure your psu is getting the correct amount of voltage and wattage
hope this helps

No power


Try these simple steps that I have below:

  1. Believe it or not, the number one reason why a computer won't turn on is because it wasn't turned on!
  2. Before starting a sometimes time consuming troubleshooting process, make sure you've turned on every power switch and power button on your computer:
  3. Verify that the power supply voltage switch is set correctly. If the input voltage for the power supply does not match the correct setting for your country, your computer may not power on at all.
  4. Check for disconnected computer power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.
  5. Perform a "lamp test" to verify power is being provided from the wall. Your computer isn't going to turn on if it's not getting power so you need to make sure that the power source is working properly.
  6. Test your power supply. At this point in your troubleshooting, it's very likely that the power supply unit in your computer is no longer working and should be replaced. You should however test it just to be sure. There's no reason to replace a working piece of hardware when testing it is fairly easy.

When i turn on my pc only the motherbroad green light comes on nothing else no fan are anything what could be the problem


1. You possibly will need to replace the power supply.
Hard to determine here with out physically seeing the PC but I 'm 90% sure it is the power supply not supplying proper voltage to the system board and hard drive. You will need a tech to check the voltage at the mother board inputs. You should have -12,+12,-5,+5 at key socket points

I have a daewoo plasma tv model dp-42sm with no video after taking back cover off found the x- sustain pcb with a burnt ic chip labeled iu4. after removing defective pcb and powering up tv set power stays...


I have the Daewoo Plasma Digital Dream model dp-42sm and it had power but no picture and my dads tv expert friend looked at it said the ysus board was out. I got the part on ebay for 125 dollars with 12 dollar shipping and put it in myself very simple and the problem is fixed. Is this the same issue your having?

DP-01FX/CD Problem


nslo, tell him to try replacing the power supply first, power supplys burn up ALL the time, as long as the plug fits and it has a rating of equal or greater amperage, same voltage, equal to or greater watts then it will work. Those variable voltage multi plug ones they sell at k-mart work but I've never had one that lasted long.

Tv Is not respondind


This denotes a problem with the power supply either the low voltage power supply of the high voltage power supply. You will need the following documents and equipment if you plan on doing this yourself: 1) a schematic diagram 2) a Multimeter 3) an oscilloscope 4) a signal generator (color bar, cross hatch, and purity) The schematic will let you know where the test points are and the level of voltage and signal are supposed o be at the test point. The multimeter will allow you to trace and measure DC and AC voltages throughout the set. The oscilloscope will allow you to view the waveforms generated by the signal generator, this is needed to tell if a component is not processing the signal in the proper fashion. The signal generator creates a standard reference to measure by. Since this prolem is in the power supply section you should determine if the problem is a blown fuse by visually inspecting the fuse. Than you will need to determine if the problem is in the high voltage power supply. You do this by checking the transistors in the horizontal section of the TV. you will find the problem either in the low or high voltage power supplies.
