I have a 20" Dell wide screen LCD model 2007WFP. It won't power up and it died after I plugged in a 6v class 2 transformer to the speaker power jack on the back of the monitor. I didn't realize at the time that the monitor was outputing 12vdc to the class 2 transformer that was NOT yet plugged into the wall. I saw the green power light on the monitor flickering and after a few seconds it went completely off and the screen went black. I then realized that I shouldn't have sourced voltage to the monitor that it was outputing the source for the speakers. I unplugged the transformer dc portion from the monitor and noticed it was warm.
What can I do and how can i find the problem with the circuit board. I don't have any warranty. Will a place like Best Buy be able to fix this?
I suspect Best Buy will most likely replace the monitor's entire power circuit. It's possible that you shorted out a fuse, the input transformer, or some other component in the monitor's power supply. The only way to tell for sure is to disassemble the monitor and check the circuitry visually and with a meter. This job is best left to a qualified technician.

rtillett, May not be "power save" problem! Possible internal component failure causing "black screen of death" symptom. What is "date of manufacture" from rear of unit? Unit could be 4-5 years old. retrevo .com lists as time to retire and buy new. You should see some video clips at YOUTUBE that show DIY owners/technicians that successfully refurbish these e172, e173 displays to help you decide to spend $20 or trade for new $200 (new unit) wide screen display. Also spand some time reading and following links you find in the fixya profiles of "budmrtn" "buddymc" "12fixlouie" that will help you decide fate of your e173fp unit. Please rate this response AFTER you do your research here and at YOUTUBE. After you discover the common power supply capacitor failure problem that plagues the entire lcd monitor / tv industry you will then be in a much better position to make decision. 12fixlouie
Hello, First check on the fuses in the panel, if bad replace with the same current rating, but if ptherwise Power supply board just die.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
There are no "user-serviceable" parts inside a LCD monitor.
So, all you can do is to take it to a qualified TV/video technician, for trouble-shooting. Or, just responsibly recycle it, and buy a new one. Some stores may give you a "trade-in" on the old one, because the LCD screen itself may be OK, i.e., the problem is in the "electronics".
Yes, If you have it sent in for repair they may be able to do it. Geek Squad would not be able to do it in the store. Although in most cases it is more costly then a new monitor. If it is still under warranty I would try and do it that way. Good luck, Lee
You may want to try and unplugging the power and video connectors of the Dell monitor. Check for anything out of the ordinary with the AC plug and the video connector. If none, plug them back in making sure that they are snug and fitted properly. If problem persist, see if it is possible to rotate the way the AC plug is connected to the mains (sometimes this works and can be done if you are not using 3-prong or the uneven 2-prong AC plug. Sometimes, this can also be done on the other end of the AC plug).
Check your docking station (though unlikely but possibly).
If still a no go and your laptop works ok, then your external monitor needs some looking at. This would involve circuit analysis and component level repair. Perhaps your best bet is to have a qualified professional take a look at it. Good luck and pls post back how things turn up or if you need further information. Kind regards.
