Laptop Inverter Repair

The problems related to the inverter is dimness or darkness to the screen in most cases or flickering of the backlight. Sometimes it can stop the screen form working at all but not usually. A common fault with laptop screens is a dark or dim screen, generally it is assumed that it is the backlight that is at fault, sometimes this may be correct, however more often or not it is simply the inverter not working, or not giving the backlight the power it needs. The inverter is usually cheaper to replace than the backlight, as the backlight is very fragile and can be easily broken. On some occasions a repair of the inverter is possible, although usually labour charges on fixing the inverter can sometimes lead up to being more expensive than simply replacing it. Inverters can come in all kinds of shapes and size, but the more common one’s are like the one shown in the picture above.

The main purpose of the inverter is basically to give power to the backlight. The way it works is simple, it takes power from the laptop itself by a small inverter lead that runs from the motherboard of the laptop, sometimes it is a direct lead on it’s own, other times this lead can be connected into the inverter through the LCD cable (the lead that runs from the motherboard to the back of the screen itself), giving the screen its visual display.

At one end of the inverter, usually the left end, the lead that gives it power is plugged into a small white socket and from the other end, usually the right side, the backlight lead from the screen is plugged into another white socket. The backlight is a very small, thin, long, very delicate light bulb that runs along the very bottom or sometimes the side of the screen.
