Question about Dell E193FP 19" LCD Monitor
Turn off pc or monitor and screen stays bright white. Must unplug to turn black.
The first thing you always investigate is what changed when the behavior began showing symptoms. Maybe something was jostled or moved or the humidity was particularly high or something but that should give you some indicators. If nothing comes to mind then try moving all electronic interference from the equation. Speakers, fluorescent lights, cable modems, etc. can all have an impact so move your monitor and monitor cables away from these things.
No luck yet? Chances are high that there is an issue with a solder joint on the power input circuit board of the monitor. First though, try a confirmed working plug since sometimes the video input plug is simply going bad. If that tells you the plug is okay then try a different monitor and see if the display problems still exist or not. If not then it's got to be the monitor and the solder connection is likely the culprit. Check your warranty and/or see a service technician to have it fixed.
If the problem persists then it could still be the connections on the video cord. There's some sort of filter/booster that people use but I don't know much about that, it might be worth looking into though.
Otherwise you need to open up the case and try a different graphics board. If you don't have an extra PCI graphics card then I would at least inspect the graphics card for damage like erupted capacitors or corroded/cracked solder spots. You'll have to look directly on the motherboard if you have onboard graphics.
I don't recommend soldering any broken solder points yourself unless you have the equipment and expertise to do so. You run a risk of damaging the components on the board from the heat generated if you don't.
