EL/CCFL LCD inverter for tablet displays

The Ruth's sister INVC378 is an internal power cable designed to drive EL or CCFL backlights in tablet LCD panels. It converts the device's internal supply voltage into the high-frequency AC required by cold-cathode fluorescent or electroluminescent lamps. This component suits repair technicians and integrators working on legacy tablet hardware that relies on inverter-driven backlighting.

Replaces a failed or ageing INVC378 inverter module

Install this unit when the original inverter no longer strikes the backlight, produces flicker, or emits audible whine. The swap is worthwhile if the LCD panel itself remains functional and the connector pin-out matches the host device. It is not for LED-backlit tablets that lack a separate high-voltage inverter stage.

Questions about this item

Does the INVC378 cable connect directly to the tablet LCD panel?

The INVC378 is an EL/CCFL LCD inverter cable designed for tablet LCD integration, providing the necessary power connection for the display backlight.

What is the correct orientation when plugging the INVC378 into the inverter board?

Align the connector keying on the INVC378 with the inverter header notch; forcing it reversed can bend pins and prevent the backlight from powering on.
