Re: Monitor comes on and says no input signal, then goes...
Get another known good cable and plug that in. If that fails, then plug into another known good computer. If that fails, then either your monitor is bad, or your video card is bad.

Unfortunately, this is a standard problem, as when your laptop goes into sleep mode, it shuts off power to the secondary monitor, without giving it the signal to go into sleep mode. You could try digging around your settings, but most likely you'll just need to turn off the monitor when you're not using it.
If it goes in to sleep mode, that means that the monitor is not getting a signal from the computer. The things to try (from simplest to most complex) are:
Make sure the computer is on and not in "sleep" mode --
press the "Caps Lock" key and see if it lights up the caps-lock light
on the keyboard.
Make sure the video cable is connected from the computer to the monitor (that the cable hasn't come loose on either end)
If your monitor has multiple inputs, make sure it's set to the right (probably analog VGA or DVI) input
If your computer has more than one video output (like a
laptop with it's internal screen plus the external monitor) then make
sure the external monitor is enabled
If none of those solve it, post a comment back here and we can dive in to the more complex tests
kkjsr00, You must narrow down the faulty component!!! You must prove what is working and what is not working!! Beg, borrow, steal a "known-good" monitor to prove your pc is operating perfectly and will display the WIN-desktop screen on it. If your pc is A-ok then visit this web blog: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ kkjsr00, when strange and weird stuff starts to appear on the screen of "cold-cathode-fluorescent-lamp" back-lit lcd displays the first place I would look at would be the units internal "switch-mode-power-supply/ccfl inverter supply".. No, No, No, unit not going to sleep!!! SMPS/inverter going into SHUTDOWN mode having detected a fault condition with itself or other circuit and is trying to save itself from catastrophic, nonrecoverable failure. e.g. smoke, fire, burn down house, etc. Do some reading in my profile and those of other fixya tech's and you will find more than enough info to help with your problem. Good luck with repair of "flakey" solder joint or bad electrolytic filter capacitor PLAGUE problem. Yes, you sure have a lot of reading to do!! 12fixlouie or old file is louie12fix also try "buddymc" , "budmrtn" profiles for more info.
TRY UNPLUGGING COMPUTER AND MONITOR AND DISCONNECTING MONITOR FROM THE BACK OF THE COMPUTER. BE SURE TO UNPLUG AND NOT TURN OFF. WAIT ONE MINUTE THEN PLUG COMPUTER BACK IN . RECONNECT MONITOR TO THE BACK OF THE COMPUTER AND PLUG IN. IF THIS WORKS, WAIT FOR NEW HARDWARE RECOGNIZED TO COME ON. FOLLOW INSTRUCTIONS, IF ANY. RESTART COMPUTER.
I have an LG Flatron 19" black w1952TQ that I bought on 2 Apr 2008; when it goes into sleep mode, will not recover. Did the online troubleshooting, reseting things, unplugging/replugging all cables, nothing works except restarting the computer, and that only works until it sleeps... Read more
