What Is a T-Con Board in a Sony TV
The T-Con (Timing Control) board controls the timing, pixel output, refresh rate, contrast, and color accuracy of your Sony TV. It acts as a bridge between the main motherboard and the LED/LCD panel. If the T-Con board fails, the panel cannot display proper images, even if the rest of the TV is functioning normally. T-Con issues are often misunderstood as common LED TV problems, but the root cause is different and needs proper testing.

Lines appearing on the screen
Flickering display
Black screen with sound
Half-screen visible or distorted
White or washed-out screen
Double images or ghosting

These are strong indications that the T-Con board needs repair or replacement.
