But most of them are easily fixable. By supplying intermediate voltages the computer adjusts the pixel's transmittance levels for its three color components, to display various combined colors and intensities. However, for this LCD Monitor, replacing only the fuse didn't work at all and the fuse open circuit again. The physical burn-in of displays is no longer an issue now that LCD displays have taken over, but while transient image persistence is not a physical burn of the device, it is an alteration of the pixel response to voltage changes (usually temporary) that prevents pixels from getting as bright as others on the screen. Symptoms. This can happen if the pixel is acting like a capacitor and is retaining a residual charge, or if it is not able to reach the level of luminance that is desired when given a specific voltage.  This is simply when pixels have lost their ability to respond to their full voltage range. You have only two choices to solve this kind of problem. When there is no voltage, no light is let through (darker), and when the voltage is at its maximum level then 100 percent of the light is allowed to pass through (brighter). Sometimes this can happen for individual pixels, suggesting a problem with the pixel itself, or it can happen to groups of pixels, suggesting the possibility of problems with the display's controller or a defect in a portion of the pixel grid. LCD screens have this problem sometimes, although it can be temporary, depending on the model and its technology. If only the backlight is malfunctioning, then the LCD panel itself should still be working just fine and should be rendering the text and images of your computer's output.

If shining an alternative light source on the display causes graphical content to show up, then either the backlight or some component involved in controlling it (such as the power inverter for it) have failed and will likely need to be replaced, especially if you cannot rectify the problem by restarting the system, resetting PRAM and SMC, or otherwise toggling different hardware and software settings on your system.

This will turn the pixels completely off and allow residual voltage in them to drain slowly over time. The LCD’s are further categorized into Light Emitting Diodes (LED), Thin Film Transistors (TFT), etc. Notice that reflected light on the right of the display reveals some graphical elements as well (click for larger view). Dell has already sent out several software updates to help address this issue, which has worked for some users. Unlike older cathode ray tube (CRT) displays that scan an electron beam over a phosphor screen to create light, LCD displays are composed of a fixed grid of tricolor pixels that change transparency based on a range of voltage levels provided by the monitor's controller.
