    Connecting to a computer and holding it at an angle with a bright light worked.  I saw the "Dell Red, Green, Blue, White" box floating around.


    So that means the lamp  is bad?  What can I do?

Unplug the monitor from the computer,
it should display the diagnostic screen on monitor in color.
if not reconnect it and boot computer or attach to a running computer with some stuff on the screen,
get a bright light and shine on the screen at an angle do you see the stuff/desktop.if you do the lamp or power supply is bad.
if the monitor is lit and the lamps work but no diagnostics then the video cpu on the monitor is bad.
post your findings here

    Normally that means the high voltage inverter that supplies power to the lamps is bad.
    its a plug in module in the screen.
    it requires taking the screen apart ,usually a easy job.
    the only real way to verify is to measure the voltages before and after that module, is it getting 12vots does it have high voltage output.
    or just order one on ebay or such.

The monitor screen blank / black and power on off switch flashes


You could check the VGA cable from the replicator to the monitor, but a problem with that will usually cause a "NO SIGNAL" message to appear. So your issue seems to lie within the monitor. It could be that the backlight has quit. That can be determined by booting the laptop and connecting it to the replicator, or perhaps to the monitor directly, and observe the screen using a good flashlight, place the flashlight flush on the screen in an area where you would expect to see an icon or some recognizable image. Look closely to see if the image can be seen. If the image is there, then the screen is ok but the backlight is out. The problem is usually the inverter. A reputable shop might be able to replace that.

Screen on Toshiba M35x S149 Laptop blank/flickers


Ok, from the beginning. Can you do a cold boot and get into the bios? (is there an image on the screen then)
Secondly, can you connect to an external monitor and see an image?
Did it do this only when it was heading in to hibernation? If so, it sounds like the power management needs some adjustment.
If there's no image on the external monitor, you may have a video/motherboard problem, or it still could be the operating system/power management.
It all depends on if you have video in bios.
Let me know.
Good luck
