Inverter board provides high voltage power to fluorescent lamps which lights up the screen. Bad inverter board will cause the LCD panel lose backlight. The symptom is the screen will flicker a few seconds and then go black. In fact, if you look closely to the screen you will still see very dim image on it.
We have special equipment to verify faulty inverter boards before we repair or replace them. Our experienced technicians can repair bad inverter board by replacing damaged or defective components. Replacing inverter board is not difficult, but sometimes we can not get exactly same inverter as customers faulty one because the inverters come from different makes and models of laptops have different shapes and connectors. In this case, we will be able to modify universal inverter board to make it to work in any laptop screen.
