To check if your LCD display has gone out: If you had a black screen you would connect your monitor to a computer (I use a laptop) and display a known pattern (I use the BIOS Setup screen) then connect the video cable to the bad monitor. Then take a powerful flashlight and touch it right up to the screen.(careful not to scratch it) If only the backlight has gone out you should see that the monitor is displaying the pattern but no light is shining through.
When the monitor turns "white screen" (and you have checked that the video board does not have bad caps) you have to replace the LCD display (which is seperate from the Backlight.) It is typically glued to the back of the glass. You can disassemble the monitor.
In the case of the White Screen problem keep the back light and replace the LCD display with one from a monitor which has gone black but still displays the pattern. (the backlight makes up most of the monitor, the LCD display is really just a thin film glued to the glass with an attached thin circuit board.
I had a white screen monitor and a monitor that had gone black so I disassembled them (not that hard about 1hr first time you do it) and swapped out the LCD displays. Now I have a working monitor and a dead monitor instead of two dead monitors.
