How do I get my monitor to turn on? While using, the LCD screen went black and the LED light will not power on

No LED No Display If Customer says there is no display on the screen, confirm whether he is able to see the Black & White Compaq Logo (No more Red Compaq Logo in latest Models) while booting. If he says no, check whether the Led is blinking or not. If it blinks, perform power drain steps. Because, this issue could be due to any charge that is left in the notebook capacitors. To check this, please try performing Power drain process. Here are the steps to perform a Power Drain Procedure: 1. Disconnect the AC Adapter. 2. Remove the Battery. 3. Hold the Power button down for 30 seconds to 1 minute. 4. Reconnect the AC adapter; do not connect the battery now. 5. Turn on the Notebook power. The above process will discharge the charge that is left in the Notebook which could cause this issue. If that too fails to work, then you may check with an external monitor. This is to confirm whether the issue is with the Display Panel or the Mother Board or Other Components. If the Notebook is completely dead and neither there is display nor the led blinks, then it might be a hardware failure. In this case, you may suggest the customer to contact ASP, if the NB is under warranty; arrange a mail-in repair service Regards, Prasad.

If the monitor connects to the computer with a separate cable, check to make certain that the monitor cable is firmly attached.

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software. Detailed instructions at http://tinyurl.com/yk5zpr
