If your getting no lights at all and no activity then that means the power board is bad. If the power light is turning on but no video then that means the screen is bad and you would be better buying a new lcd then replacing the old one cause it can get expensive.

Power off ac adopter is ok


remove the rear cover then tried to make a voltage checking since as you said the power adapter is good so what you need is a voltage checking going inside. you need a digital tester then make a voltage checking at the lcd control board if the dc supply goes through or not present. you can check also a bulged capacitor or burnt parts at the lcd control board.

I have lost the original power supply for my dell 1701fp monitor. I have a power supply that I think may work as a substitute until I can replace the original. I need to know, what the acceptable voltage...


What ever you use, it must be REGULATED power supply that will maintain 14vdc output, rating at 3A. These regulated power supply can easily maintain the output voltage within +/- 5% with input AC voltage range from 100~240vac.
Linear regulator power supply may not work since it has slow response time to regulate the voltage.

Flashing green light and no picture. Resetting the power source and the connections won't work.


Open the monitor and find the power PCB. Look for blown capacitors. Replace all low voltage capacitors even if they look OK.
The power PCB is overloaded by shortage in these old capacitors.
If the monitor is not fixed now, replace two more capacitors - the big one, on 400V and a very small one on 50V in the high voltage circuit.

Monitor flickering


Monitor flickering can be one or several problems.
Depending upon the age of the unit and value, you should decide weather to repair it or replace it.!
More than likely, it is a problem in your power supply.
The capacitors in the supply will leak and most often crown.
If when you start unit after sitting for a while, it shows good and then after a few minutes it starts flickering, you can bet it is one or several capacitors in the supply.
This monitor is a 17 inch and not really worth the time and investment to repair, unless you have the technical skills to remove and replace electronic components.

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.

The dell monitors are bad with capacitors going out, check caps in power supply and video board. You can use a can of freeze, it would be easier that way. Just be careful not to touch anything, because these monitors can shock easy.
