LG 43 or 49-inch 4K TV showing vertical lines, half-screen black, or distorted colours? The T-Con board 6870C-0738A is the timing control board for LG's 43 and 49-inch 4K LED panels — one of the most common LG TV repair parts.
What Does the T-Con Board Do?
The T-Con (Timing Control) board drives the LCD/LED panel's row and column signals — it converts the digital video signal from the main board into the precise timing patterns needed to activate each pixel row and column in sequence. When the T-Con fails, the result is typically: vertical lines, bands of missing colour, half-screen image, or complete black screen (with backlight still working).

FAQ
Q: How do I find the T-Con board number in my LG TV?
Open back panel — T-Con is typically mounted at the top of the panel. Board number printed on the board. WhatsApp photo for free confirmation.
Q: My LG 4K TV has vertical lines only in one area — is this T-Con?
Yes — partial vertical lines in a band are classic T-Con fault. Full-width lines could also be panel damage. WhatsApp your TV model for diagnosis before ordering.
