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

Dell E173FP 17 monitor went dark and not working. I restart the pc it shows for only few second and went out again. I plug in one other monitor in my pc and it work fairly well. So something not right with...


Hi!

There are three possible cause why your monitor went black and start working..

1. If your monitor is dead set.. no reaction or lights turn on after power on.. then it needs to check if there is blown capacitor in its power supply section..

2. The high voltage ballast transformer of the backlight inverter is burned - it needs to be replaced so that it will not have a direct effect on the power supply section of the monitor.

3. The backlight inverters are all busted - the backlight was located at the upper and lower back edge of the monitor.. If these lights are busted then all that will be seen in your monitor is black screen.. It will need to be replaced so that image display will come out from your screen..

These 3 reason and its solutions can only be done by yourself if you have the knowledge, proper skills and the right tools to open the back cover of the monitor and replace the problem parts....

Otherwise, bring your monitor to a credible technician and if there is warranty,, avail of this...

Hope that answer your question..

Much appreciated if you rate this help..thanks..

Video cards that can handle two monitors at the same time have cables with two plugs on the monitor end.

If your video cable has two plugs on the monitor end, try the other plug.

Display goes black after 5 minutes


Repairing the DELL E171Fpc LCD Monitor with the complaint of display shutdown after few seconds (power LED still on) was not difficult. Normally when this type of problem happens, we would first suspect the inverter board, then the filter capacitors and lastly the main board. A defective in one of the lamps and a faulty TL1451AC PWM IC or inverter ic may caused the display to shutdown as well. If the lamp is defective, it will send a feedback to pin 3 or 14 of TL1451AC IC and caused it to stop producing output signal thus the display just shut off once you switch it on.
