If the picture disappears from the screen and the
1 (power) indicator is green
Turn off the 1 (power) switch and disconnect the
video signal cables from the monitor.
Turn the monitor on by pressing the 1 (power)
If all four color bars appear (white, red, green, blue), the monitor
is working properly. Reconnect the video signal cables and check
the condition of your computer(s).
If the color bars do not appear, there is a potential monitor failure.
Inform your authorized Sony dealer of the monitor's condition.
Be sure to note the model name and serial number of your

jlallen54, When lcd panel goes to a dark condition please shine a bright flashlight 1 inch from screen an tell me if screen data is still displayed during this "blackout" condition. It might be just a single (1) poor and now thermally intermittant solder connection on the printed circuit board inside the monitor. Do some reading first and then you will understand the problem that your monitor has. 12fixlouie
When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself.
