Take the computer into a darkened room.
Can you read the screen? Does the text/icon on the screen look "normal"?
If so, then the "back-light" on your LCD has failed.
It's about $20 to replace the part, and about $60 for the technician's time to replace the part.

Compaq Presario CQ50-110US...blank screen, no display


Can you see what's on the screen if you hold it under a light? Did the screen die suddenly or were there more symptoms?

GE Profile Artica - Water & ice dispensor not working.


This could be as simple as the door switch or as complex as the dispenser control board. I would try the door switch first. When the door is close it turns on the dispenser controls. If the contact is defective in the door/light switch then this happens. Unplug remove the door switch and mark wire locations. 1 Powers the lights and the other powers the dispenser. and one is the power itself. Sea Breeze

My HP Pavilion dv5000;s monitor is blinking!


This is a possible problem with the inverter that powers the back lighting panel or it could be the power adapter connector on the latop.
Wriggle the power connector which plugs into the laptop, if the LCD screen flickers then the power connector is faulty or needs resolderng (repairing).

When mine goes time I squeeze the radio downward into the cradle and it lights back up.
Might be a weak connection. I'll have to hit it with contact cleaner sometime to see if it helps.

Screen is on but picture dose not show... cables connected


Solution, replace monitor with a new one.
I have found, at my shop, that getting parts for these things can be pricey and by the time I charge labor as well, could just buy a new one.
Probably a bad internal power supply or the inverter that powers the bulb(s) went out, which is sometimes built in with the power supply itself. If, and I stress IF, the parts are available, be prepared to pay more than its worth.
Pick up a new one, shop around on different brands. Some manufacturers offer 3 year warranties. ;)
