No power- no lights - Lexmark E234 Laser Printer

Have you tried turning it on using your adapter? If there is still no power light, try removing the power jack in the laptop and the power cable in the adapter and re-insert it both then plug it then test it again. If there is still no power light, try bending slowly the power jack cable in the laptop while inserted and slowly bend and move until you reach the power adapter. Observe the power light while bending the cable. If the light turns on while bending, the wire/s on the cable might be cut where you bend and see the power light turning on. If there's still no power light, your power adapter or the laptops power supply might be defective.

Ok This is how to troubleshoot the TV, there are lights on the front and you are mainly concerned with two of these lights (the power light and the OPC light). I) If non of the lights come on then this is a AC Power failure (There is a loose connection or you need to check the Power/Inverter unit or the Main unit) II) If the power light is blinking at a rate of one blink per min and the OPC light is off (then there is a CCFL backlight problem) III) If the power light is blinking at a rate of two times per min and the OPC light blinks at a rate of one time per min (13V/UR10V failure you need to check the Power/inverter board or the main board). IV) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of two times per min (3.3V Main Failure check power/inverter board or Main board). V) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of three times per min (UR6V failure check power/inverter board or Main board). VI) If the power light is blinking at a rate or two times per min and the OPC light blinks at a rate of Five times per min (Panel 5V failure check LCD control unit or control panel).

The power red led indicates that your device is "power on" , but the status led still red and turn to green if the device ( video input )received video signal ( from DVD player, Laptop etc. ) .

Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.

the light on the motherboard indicates power to the board, so it's completely normal. that might be the same for the power button light.

disconnect power supply from the router, wait for 30 seconds , and reconnet it back then check you get the power light.. if not try in a different power outlet..check the physical connection, the modem should be connected to internet slot in the router ,so that you would find the internet light lit up.., if still you do ont see the power light or the wlan light, reset your router, if you look at the back of your router, you would find a reset button, press and hold the reset button , with a pen on paper clip for 30 seconds with the power cable connected and disconnectc power and reconnect and then check..if still not the problem is with your router
