Having problems with your Samsung SyncMaster 940BE 19" LCD Monitor ?

No Video on Monito - Blue Power lite is on

\015 We have a Samsung 940B monitor that just quit working one day.\302\240 We've checked connections (even swapped them).\302\240 We have the front panel power on light (blue).\302\240 But the bottom line is there is nothing displayed on the screen, even on power up.\015\012\015\012Should I tear in to it, or just junk it?\015

Answers :

Hello.
\015\012Sounds like the backlight inverters or CCFL tubes are at fault.
\015\012Turn the monitor on with it connected to a known good SVGA signal source that is sure to have video. (Like the computer when it is operating.)
\015\012Hold a flashlight to the screen of the monitor and see if the faint video can be seen through the screen.
\015\012If the video is faintly present on the monitor screen using this method of illumination, then either the CCFL inverters / Inverter board has failed, or the CCFL tubes themselves have gone bad. (CCFL = Cold Cathode Fluorescent Lamp)
\015\012This should give you a better idea of how to proceed, repair or replace.
\015\012If it is the inverters or CCFL, Repair costs for a DYI project could range from $70 to $120 depending on the level of your expertise and parts availability.
\015\012Good luck with your quest.
