Plug the power cord directly into a wall power outlet, and make sure that the standby light is lit (turn it on/off manually to see if anything changes). If there isn't any light, then it's most likely broken.
If the TV works again, being plugged into the power outlet in the wall, then the problem is with the cable box (i bet you figured that out too).
The most common reason is because of temperature. Make sure your power box is out of an are where it can heat up too much. If it does, it won't turn on till it is cooled off. Another reason is because of too much voltage or current. To solve that, simply try other plug ins, that always seemed to work ^_^ I bet it really is temperature, just put it in a more open are where it doesn't get too much heat, let it rest, and play on!!!!
Hope this helps ^_^
Check your outlets first. If using a uniterruptable power supply (ups) check circuit breaker on the UPS. If no worky, unplug the computer, then plug in a lamp or something that you can identify as truly ON.
Assuming it lights up, plug the computer directly to the working wall outlet. If the wall outlet doesn't work, go find the circuit breaker box, and reset as needed.
If wall/power strip/UPS, circuit breakers are in/closed and all work and the computer still won't power up. You most likely need to replace the power supply. Pretty straight forward. Unplug from electricity source. Ground yourself before you start jackin' around inside. Then look at the plugs going to the motherboard and drives, note orientation, color and pin placement. Yank it, toss it, replace with new http://r.ebay.com/BYvShq.
Hello. Hope you got working already. But if you're still having the problem, unplug the power supply (the small black box behind the printer where the power cord is attached) with the other end still plugged in to a known working power outlet. Look around the black box, it should have a green LED on around the silver contacts. If not, properly secure the power cord by unplugging and plugging it back in. Otherwise, you got a defective power supply. Try not to use extensions or power strips, plug printer straight to the wall power outlet or plug it to a different known working power outlet. If the power supply is working fine, plug it back in the printer in a correct position. Properly insert it and make sure it pushed all the way in the printer. If you're still getting all blinking lights once plugged in, your printer might be damaged by the the lightning strike. If that's the case, you can call Lexmark and ask for assistance with that. Well, these are the troubleshooting steps you can do to determine where the problem is. Good luck!
you can try plugging the printer to a different known working power outlet in the wall. If still not turning on, try to unplug the power supply (black box) behind the printer where the power cord is plugged in but the other end still plugged in the power outlet in the wall. The power supply should have a green indicator light on. If not, check any physical defects on the cord or the power supply itself. If on, plug it back in and make sure to plug it in correct position in the slot. Note that it can be plugged in incorrectly so just double-check the position of the power supply itself. Hope this helps.
Hi, Yes I had the same problem. One of the solder joints on the relay was cracked but hardly visable. Resoldered it and no problems. How to do it: Make sure you turn off the power at the wall and pull out the plug. To get to the circuit board remove the screws on the inside top of the door and pull out the front panel (where the buttons are). Press the little clips and the white box containing the circuit board comes free. Remove all the plugs and lever open the small clips holding the box shut. After you open the box pull the circuit board up and have a look at the contacts under the black little box (relay). Use a soldering iron and some flux cored solder and redo the joints. Put it all back together and turn on to see how it goes. Worked for me. All the best......
Make sure you have power at the outlet. Take power cord off and remove battery. Hold power button down for 10 seconds, plug just power cord. Try to turn on. If dose not work , you have a hardware issue.
Check the power source to the computer (both ends of the cord), if a surge protector is in line with the power , remove it and plug the computer straight into the wall. also check the wall plug with a lamp or something to ensure power there. make sure the switch on the power supply hasnt been changed to the 220v side.
If no power at the wall- check your breaker box in the house
If it works plugged straight into the wall- check the surge protector
If power at the wall and plugged straight into the computer (no surge protector) and nothing lights up when you turn it on- have your power supply checked.
I too have the same problem. We've had the ilo27 for almost 2 years and
it suddenly decided to not turn on anymore. Red light-itus.
I did find a little trick if you are not so mechanical like me and don't want to risk opening the back. I know this isn't a cure, but you CAN get around this by simply pulling the plug from the wall and plugging it back in. It comes on with remote or manually every time!!! A little inconvenient, but a way around it temporarily!
