Please see my pictures here and look for bad caps as shown in my pictures.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor stays on for two seconds and cuts off.


First place to look is the caps in the power supply section, look for caps with bulging top, replace all will be best bet even you only find one bad cap. Here are the boards (there are two versions): http://www.lcdrepair.us/1704fptt-1905fp-inverter-power.html

Fist place to check will be the power supply, look for bad caps with bulging tops, check to see if you do have 12vdc feeding the back light inverter circuits, see example of failed monitors (90% are due to bad caps): http://s807.photobucket.com/home/budm/allalbums

POWER BUT NO ACTION


Push and hold your on power button for 2 seconds. Or just hit and hold a channel button for a few seconds.

I have had the same problem. I've just managed to get the monitor working again by VERY QUICKLY navigating through the monitor setup menu to the 'factory reset' option and hitting reset before the screen had a chance to blink off.

The problem I had is that the monitor suddenly goes black, but will come on for five seconds if I switch it off and on with the power button.

In that five seconds, I had to...
>Hit the menu button
>then hit the '+; button once
>then hit the menu button again
>then hit the '-' button
>then hit the menu button one last time

The above brings up the menu, scrolls up off the top of the list to the last item on the list (Factory Reset), selects Factory Reset, selects 'All settings' and resets the monitor.

I don't know if this is a permanent fix, but it just worked for me and mine has been doing this intermittently for the last week.

Give it a try, it's frustrating and will take a few tries, but it can't hurt.

Dell E173FP - After sometime the screen switches off


Sorry not a solution - but I have started experiencing the exact same problem over the last month although sometimes, on switching on again, it will run for 10-15 minutes before the problem re-emerges. Initially I put it down to the v. hot weather in July but it still continues. So I would also appreciate any solutions!
