Has power but no display

If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

Dell LCD Inverter

See some examples here, just remove the stand first and start cracking it open at the bottom edge first.

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..

Sounds like the monitor is cycling power.
Try plugging the monitor into a different power socket. Try not to use the same power bar as your computer

Nothing. Power supply faults in there. Open the monitor and replace all "popped" electrolytic capacitors - they're causing the power supply get overloaded.

It means the display is in power save mode. This status occurs when the display is on but not receiving any signal.

try to contact dell. Maybe the power supply inside the case is bad. Try without VGA input. It should say dell genious display

hi, check out the micro switches on the monitor.. let me know..

I just had the same problem as well - mine happened during a windows update, related? Also, for me the monitor doesn't come one even after disconnecting from computer, nothing, just blinking green light.
