I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.
alastairhaig, Is unit 4 years old? Could be problem with units switch-mode-power-supply if same thing occurs when connected to fully functioning different pc that has all screen saver and power save features disabled. After screen goes "black" do you still see the WIN-desktop screen and icon's if you hold a bright flashlight at different angles about 1 inch from the screen? SEE = power supply in "partial shutdown" mode. NO SEE = smps in "full shutdown" mode. Do some reading in my fixya profile about "black screen of death" repairs. also read FIXYA profiles of "budmrtn" "buddymc" and other fine profiles of technicians here on fixya. You will truly be amazed when you visit YOUTUBE for video clips of owners/technicians who save their cold cathode fluorescent lamp, back-lit lcd monitors from the "trash-heap"!!! After you do your research please return here and rate this response and possibly do additional comment. 12fixlouie
magazine991, Use your warranty first! It's free! The internal "switch-mode-power-supply" has gone into partial shutdown mode. If you couldn't see the faint image on the screen using flashlight 1 inch from screen then it would be in FULL shutdown mode. You must have very good vision!!! Now all you need to do is get into my fixya profile and read, read, read!! Your monitor's basic design and operating principles are NO DIFFERENT than any other brand of CCFL back-lit LCD unit! Find out all your options on what you can do with your now BLACK but not BLANK monitor. Do not rate this response till you want to break this link. Do make a comment for more info if you still don't know what to do. I'm 12fixlouie Bye for now
nyounger4242, Very common problem!! learn to do flashlight test to evaluate "switch-mode-power-supply" status. Read my FIXYA profile to find out all you need to know about Black, or Black and Blank lcd screen fixes and the options you have. Your monitor NO DIFFERENT than any other CCFL Back-lit LCD monitor in it's basic design and operation!! Good luck with repair. Use warranty if possible. Read, Read, Read, before you do anything!!!! 12fixlouie
autotech_2, Your monitor if it is an LCD "cold-cathode-fluorescent-tube" backlight type of display your "switch-mode-power-supply" has partially or totally gone into SHUT DOWN mode to save itself from "catastrophic failure"!!! Please go and visit YOUTUBE and search for "LCD disassembly", and "LCD REPAIR" video clips. It will be very helpful to you in making a decision about what steps you should take in getting it repaired and or replaced. Some lcd displays can be fixed by their handy and crafty resourceful owners for $10-$15 dollars. Your problem of a DARK and or BLACK display is quite common complaint. Although you didn't give any history (did monitor have nice,bright, screen prior to the failure? or the AGE of your unit?, approx total "ON" hours of unit?) I still suspect that it is a SMPS/INVERTER probllem. Find out all you can about Swollen electrolytic Capacitors and other common SMPS/INVERTER failure modes of LCD monitors. I hope this info was of some help to you. l'm louie12fix on fixya or lmistyrel @ aol.com please rate this response on fixya. Bye for now.
