Dim Screen and dark image problems

Has the light gone out on your laptop? . One of the most common calls we receive is for backlight problems. You may look at your screen and it looks as if the light has gone out, but you can still see the image. Sometimes you have to look very carefully at the screen, you may just detect a faint image. Backlight problem? What causes an inverter to fail? Inverters get very hot inverters often die in hot countries so there are few problems over here !!. Some feel their screen needs to be changed but its not your screen don't worry its not your screen its just your inverter. When you plug an external monitor to the back of your laptop you will see a perfect screen displayed externally. The dim screen problem is the result of inverter problems. Also dim screen backlight problems are caused by failing backlights. ( hopefully your onboard graphics card is not broken or damaged.) On an inverter is a small fuse always check this first because sometimes this blows and you need to replace it. Has your backlight suddenly gone out ? Has the tube just died?. The chances are the backlight is working perfectly but your inverter is not working correctly. Backlights rarely have problems, Inverters just die quite often. In some cases your tube may need replacing. So thats how dim screen problems are resolved.

On some occasions the power manager chip on the motherboard has got a problem.

Engineers some times try to change parts on the inverter and if they replace the wrong power manager chip they can blow the motherboard. **Inverters convert 19 volts to over 600 volts so they are dangerous to mess around with if you are not sure what you are doing.
