What is a backlight inverter?

Backlight inverters are found in older, CCFL style TVs only. These boards convert low voltage power from the power supply board and send out high voltage power to the fluorescent tubes behind the LCD screen. These tubes then light up the screen.

Which symptoms does a backlight inverter fix in a TV?

•  If you see very dim video or no video on the screen, but you know your TV has power and is on, then your backlight inverter(s) could be bad.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace a backlight inverter?

It's easy! Once you match the part number on your backlight inverter(s) with the part number listed on this page to confirm compatibility, you’ll just need a screwdriver and the ability to remove the back of your TV and replace the board(s).

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.
