Dell E173FP 17" LCD Monitor Logo
Anonymous Posted on Sep 17, 2010

I have a similar problem to one posted a few months ago - flashing LED on the power button, except the monitor does come on after a couple of minutes and the LED stops flashing. bdmrtn said to the other poster: "You may have shorted out transistors in the inverter circuits, common problem. Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). " Would mine be the same possible problems, just less far along? The problem just developed last night.

    mmckitri, May very well be your Dell e173FP has same failed components as stated by "budmrtn". Just tell us the "brand names" of the capacitors (electrolytic filter caps) you find populating your monitors "switch-mode-power-supply / cold-cathode-fluorescent-lamp-ballast circuit board" !!!! Are any of them named "CapXon" or "ELITE" or "Jun Fu" ??? If you find any of them I suggest you make sticky lable and place it over the Dell logo of unit with new name of : CrapXoff!!! Good luck with the repair. 12fixlouie

    We replaced the 2 leaky capacitors, crossed our fingers, and w00t! The monitor is back in business. The old capacitors were rated at 10V, and we replaced them with 16V ones.

    Thanks so much for your help budmrtn!

Look real close at the solder joints on the inverter transformer pins, and the transitors. What usually happen is that the cold solder joints will mess up the bias on the transistors or causes arcing and that will take out the transistors, you need good magnifier glass to see, you will see ring/cracking around the component's leads.

It will get to the point that the transistors 2sc5707/5706, and also still should look for bad caps.

Lcd monitor power light flashing with no img. seems 2 be frozen

The display is in safe mode and you will need to reset the display to get the display out of the safe mode. There are 2 different model revisions. Please choose the method that will match your revision. Depending on the revision of the monitor, one of the following 2 methods should reset it to a normal state. This reset generally requires both hands and it is sometimes easier with another person.

If the serial number begins with an A and/or your power button on the far right (5th button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.
Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.


If the serial number begins with a B and/or your power button is in the middle (3rd button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see attached picture) and while continuing to hold the buttons, plug the power cable back in.4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

If you have tried the reset a few times and it does not solve your issue, please Ask a Question to submit a request through the system or call 1-866-752-6271 Option 1 to contact technical support.

Sony GDM-F500R (G1 Chassis) has trouble turning on

sometimes relay contacts get "sticky" from arc oxide corrosion whenever enough electricity is passed from metal to metal...in a perfect mechanical relay, the relay would be sealed in a vacuum. Try swapping relays to transfer the problem. If you can transfer it, you found the bad relay. I actually have disassembled relays and polished their contacts with great success.
