Michael Sampino The corroded capacitor is reference designator C7797. It is a 10uF 50V 10% capacitor in a 1210 case. It is part of your backlight driver circuitry. You could check it for short to ground, ubt I'd replace it anyway. As for your backlight, just test it on the LCD connector. Place your multimeter in diode mode. Red probe on ground and black probe on either 3 or 4. Let us know what you get. As for voltages , Black to ground red to pins 3 or 4 and meter in volt mode, you should get around 27V or higher on a good working system, Again , let us know what you get.

You could check it for short to ground. I'd replace it anyway since it does show corrosion on it. As for your backlight, just test it on the LCD connector. Place your multimeter in diode mode. Red probe on ground and black probe on either 3 or 4. Pin 1 starts closest to the particular capacitor. Let us know what you get. As for voltages , Black to ground red to pins 3 or 4 and meter in volt mode, you should get around 27V or higher on a good working system, Again , let us know what you get.
