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.
• 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.
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).
A T-con board — short for “timing control board” or “timing controller” — is found in LED and LCD TVs. This board converts the video signal from the main board and sends it directly to the screen to display the signal in the correct order and at the correct spot on the screen.
• If your TV has no video, then the T-con board could be bad.
• If your TV only has video on a fourth or half of the screen, then the T-con board could be bad.
