What does it mean when the power button blinks rapidly on my Dell E178FPb monitor?

The monitor will not turn on, and the power button light blinks rapidly but will do nothing else. I cannot turn the monitor off or on and it gives no response to moving the mouse.

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.

SOURCE: blinking monitor power button and flashing image

I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

SOURCE: Dell E173FP stuck in power save mode

Just had the same problem... what worked for me was simple. Unplug the cable from the monitor, hit the power button a few times until Dell screen poped up with a few color bars because it knew it was no longer connected to a PC. Then plugged the cable back in and all was fixed.

SOURCE: Dell 1704 FPt lcd monitor power button blinking green, no screen.

the only thing you can do, is to get a qualified service technician if you are not an electronic expert. because the problem is in your power supply and inverter board. due to heat pressure inside can damage components specially capacitors.

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

What does theblue light mean when its blinking


the steady, blinking blue light means it is working. If the light blinks quickly, ususally 3 times, then it is either turning itself off or turning itself on. if you're getting a steady blink, try holding the button down long enough for it to flash rapidly 3 times in succession. after that, it should blink no more, because you have just turned it off. Want to turn it back on? hold the same button down until it flashes rapidly 3 times again, and you have just turned it back on.
