In all modern laptops for the backlighting system, which is located inside the liquid crystal matrix, special lamps are used. These parts can only function under high voltage. To start them, an alternating current with a voltage of 1.5 kV is required, and it can be provided only from voltage from 600 V to 1000 V. Therefore, an inverter is used, which converts a low-voltage current into a high-voltage one.
How to determine the breakdown of a laptop inverter?
The consequences of the inverter are the same as the failure of the backlight indicator. Therefore, in both cases, if the element is out of order, then the brightness of the laptop will be minimal, and the image is barely noticeable.
There is a universal way to make sure that the inverter broke down. To test, replace the inverter with the one that is exactly working, or connect.
The most common cause of inverter failure is the failure of the transformer in the control circuit. The owner of the laptop can hear an unpleasant noise or a squeak, which will transform out the transformer.
Do not repair the laptop inverter yourself. In most service centers, the price of replacing a laptop inverter is fairly democratic. Undoubtedly, today on the Internet there is a huge amount of money that helps to make repairs yourself. But remember that there may be a situation where an inexperienced master closes any contacts, and this leads to damage to the laptop’s motherboard.
