Dell E176FPB Monitor turns off a few seconds after being turned on. Have to press the power button again. Then it turns on for a few seconds & off again. Press the power button yet again. Then it turns on again for a few seconds & off again. And so on..
My_secret_mb, Stop pressing the ON/OFF switch! It's broke!!! The unit's internal power supply will need some work done on it. Unit will need to be evaluated first!! This is a common problem for ALL LCD monitors. If unit out of warranty period, then you will need to do some intense speed reading of my higher page number responses in my fixya profile to understand the problem your cold-cathode-fluorescent-lamp back-lit lcd monitor has and the options that you have. You will also need to base your decision on the age and total number of "ON" hours unit has seen during it's lifetime. Do not dispair or feel sad about what has happened to your monitor. A low side guess would be 50 units/day fail world-wide. Your unit may have failed filter capacitors or possible failed solder joint on printed circuit board. (thermally intermittant) I hope this helps you. 12fixlouie north of "Windy City" USA
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Dell and other monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

has shut down. Instead, this allows your monitor to essentially turn
off until it's needed again. You can change how long it is before the
Dell monitor goes into power-save mode by changing your display
settings.
