I cannot get my HP L1706 monitor to switch on. The screen remains blank though the computer seems to be working and I can hear the welcome sound on windows. The power button of the monitor will also not stay on, but wll light up green only when I press it. Earlier it would blink for a long time and then the screen would light up. Now it's not even blinking and absolutely nothing in showing on the screen. Help!

Re: HP L1706- screen is blank when I switch on
First if you have a extra monitor try to plug it in and see if it works. If not then check your video card. or get into the computer and try and remove and reseat the memory. Sometimes by just doing that can solve the problems

With the price of monitors these days, you can pick up a 19" new for less than 100. Or you can find them used for 50. I would replace it, but if you want to keep it, the go to HP web site and get an user manuel and try to adjust the settings.
huntpercell, You won't !! The unit's "switch-mode-power-supply" is in what is known as "SHUTDOWN" mode because it has detected a FAULT with itself or the "cold-cathode-fluorescent-lamp's" electronic ballast circuit which is called the INVERTER circuit which changes 12-15volts DC to 800-1200volts AC to light-up it's CCFL's to produce WHITE LIGHT so you can see all the pretty colors on the LCD panel!!! Do this test!! With KNOWN GOOD pc fully booted to WIN-desktop, reconnect l1706 to pc and wall outlet. Then and only then turn on the l1706. Make note of how long it takes to go to BLACK or BLANK screen. After screen shuts down then hold a bright flashlight 1" from the screen at different angles, looking very closely to see if the desktop is still being displayed very faintly even though the screen appears to be BLACK! Tell me what you see or don't see! If you don't see the desktop then SMPS is in total shutdown. If you see the desktop the SMPS is in partial shutdown but is still able to source +5 or +3.3v dc to the VGA/LCD interface board to send information to the LCD panel. You have just performed THE FLASHLIGHT TEST that every owner of a CCFL backlit LCD display should know how to do! Now here are your options as a CONSUMER / USER of a LCD display whoose screen is now dark and lifeless. 1. Trade it in for a NEW one. $$$$ 2. Swap-out unit for manufacturer refurbished unit. Cash +old unit. $$$ 3. Repair/refurb unit locally at TV/monitor shop. $$$ 4. Effect a repair on your own with info acquired via web. $ or poss $$ If 4 is of interest then get back to me. I will tell you of some good sites to visit. If you found this information helpful, please rate this on fixya. I'm louie12fix on fixya or firstname.lastname@example.org Bye.
Your video cable has a broken pin inside. Check the cable at the videocard end (bend it in different directions) and do the same at the monitor end. It should become normal, then it's just a case of keeping it in the right position or replacing the video cable.
