Question about Dell Computers & Internet
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.

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.

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.

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.

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

Tips for a great answer:
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
