Monitor comes on and goes right to a black screen like the power was turned off but the power light is still green.


hi,
You have to check the back light of your lcd monitor. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

A menu keeps flashing on my monitor so fast I can not read it and it will not stop. Black box with grey edge. Compaq 5017M monitor


mrsrobins849, if monitor manufacturing date (on rear of unit) is anywhere close to 2003-2004 then trade unit for new wide screen only if problem of flashing "menu" goes away when you connect a borrowed substitute monitor to your pc. Will your monitor "act" same when connected to "known-good" "fully-booted" pc that will display the WIN-desktop?? Most problems with "cold-cathode-fluorescent-lamp" "back-lit" lcd monitors can be attributed to their internal or external "switch-mode-power-supply" DC voltages degrading over time with use.

My ViewSonic VG1930WM (Black) LCD Monitor wont turn on


You need to open it up and the first place to look will be the power supply, look for bad caps with bulging top, post back what you find so we can guide you further. See example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Screen turned black


your monitor got a hardware problem:
1) the LVDS controler board out of work, only change or repair it could be fixed.
2) if you can see some show like smaller signal detect windows in the centre of screen a very short time (bright flashing one time), this is inverter board damaged or worn lamps, thay all need repair or replace
hope give you some idea. please take a rating let me know how much helped you thanks!

Monitor flashes on then goes black.


I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

Two problems vx922 Black screen of Death and vx910 no power


You may want to tey another computer or another cable or update your video card drivers. Otherwise look very closely and see if you are able to see a very faint image of your background picture or icons if you have any.

Really im not kidding it might be a backlight issue.
