Re: dell e173fpf lcd monitor is grey

Sounds like the AD section of the board may be junk. I did the same thing - bought the board from

I submitted an RMA request to get a replacement. The process was difficult due to the pdf form they make you fill out. Lots of errors and no good way to submit it, since it wants to use outlook, but the pdf isn't configured properly to do so. Seems fishy, but I'm giving them the benefit of the doubt for now. We'll see.

In a dell e177fpf lcd monitor all the capasitors fuses diodes in power supply and inverter board are ok.but the back lights remains 2 seconds.

Hello...I recently opened up my Dell E173Fpf monitor because the screen went black, yet the power button was green. I thought it was a capacitor problem. But before doing anything I gave the board a thorough inspection, looking for anomalies. I observed a substance, (later identified as silicon) puddled around the power connections. I gently removed the semi rigid stuff and didn't touch the capacitors as I had originally planned. I partially reassembled the monitor for a test run and it worked again. (Being 9 years old, I don't know for how long...) Only thing I can think of is that a spill happened at the factory and over the years it gradually "melted" to puddle around the wires behind the power input. (Weird, but that seems to be what happened.)

Have a dell E152FPb flat screen monitor which doesnt stays black even when on light is green. have taken back off but no obvious bulging etc. what can i try to get some life back imto it please

The backlight controler board is faulty. You can try replacing any capacitors in this board even if they look OK. If this does not work then you need to replace the inverter board with a universal inverter board - you will need to work out the wiring details though.

I have a Dell e173pfb monitor. i push the power button and green light comes on screen comes on for a second with no problem then the backlight goes off. I can still see an image with a flashlight though....

You need a new backlight inverter board. If you dissasemble the monitor you will see a circuit board with 4 2-wire connectors connected to it. This is the board you need to replace. Typically they run from $15 to $40. Usually just easier to replace the monitor. Another idea is to reduce brightness levels on the monitor in the menu while looking at it with your flashlight. Then power off then power on the monitor and it might stay on longer.

Dell E173FPf lcd- no picture,steady green light

E173FPf Mfg December 2004
This E173FPF has changed much inside from the November 2003 E172fpb which had the famous 4 identical transistors 5707 that would tend to fail in pairs. If your newer E173FPF displays a green power light and fails to display a picture try replacing the 220uf25v capacitors at C6 and C26. Test them with a volt ohm meter and they will test Ok, replace them anyway. Radio Shack did not have the 25v so I used the 35v, display works fine now. There is an E173FPF repair kit with directions available on Ebay if you don't have a parts store in your area and would prefer delivery.

i'm not an expert at anything...x'cept maybe dumpster diving. God Bless
