Re: Dell E172FP 17 monitor keeps blinking

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

The power button is not working it blinks a green light

Disconnect the display from the Computer and remove its power plug. While the display is turned off, press and hold the power button for 30 seconds. After two minutes connect the power cord and the display cord to the Computer and the power source and turn it ON.

If the power indicator on the display keeps blinking, then it's required to open it up to repair it.

My Dell Monitor on/off switch blinks green all of the time.

You need to open the monitor and check to se eif any of the capacitors on the power board are bad. Common problem for LCD monitors. The bad caps usually vent at the top (they will look bad compaired to a good capacitor).

If they look bad then they will need to be replaced. I've seen this in Dell monitors, so there's a good chance this will fix the monitor.
Take it apart, get the values on the sides of the bad caps in the power supply pcb. Buy new caps, and de-solder the old ones and replace them with the new ones. Don't forget to trim the leads afterwords.

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.
