Common T-Con Board Issues and How to Fix Them
The T-Con board (Timing Controller) is one of the most critical hardware components in a TV, responsible for managing video signals and synchronizing them with the display panel. A faulty T-Con board can cause issues like black screen, color distortion, flickering, and horizontal or vertical lines. In this article, we’ll explore the functions of the T-Con board, its types, and how to replace it. For professional TV services, visit Lavahandyman.com.
Common T-Con Board Issues and How to Fix Them
What is a TV T-Con Board and How Does It Work?
The T-Con board converts the processed video signals from the mainboard into a format that the display panel can interpret. It regulates key parameters such as brightness, color, and refresh rate and transmits this data to the LCD, OLED, or QLED transistors.
💡 Without a functional T-Con board, your TV screen won’t display any image, even if the sound is working.
Types of T-Con Boards and Their Differences
🔹 T-Con in LCD and LED TVs
In LCD and LED TVs, the T-Con board manages video signals and frame rate (FPS). The key difference between models is the resolution and refresh rate compatibility.

🔹 T-Con in OLED and QLED TVs
In OLED and QLED TVs, the T-Con board is more advanced because it must control the brightness of individual pixels separately. This results in better contrast, deeper blacks, and more vivid colors.
🔹 Integrated T-Con in 4K and 8K TVs
Some smart TVs (4K & 8K models) have a built-in T-Con board, improving processing speed and reducing display latency.
Signs of a Faulty T-Con Board
❌ Black screen, but sound still works
🔹 If your TV is on but shows no picture, the T-Con board might be faulty.
❌ Color distortion or vertical/horizontal lines
🔹 A damaged T-Con board can cause color shifts, pixelation, or unwanted lines on the screen.
❌ Blurred image or screen flickering
🔹 A malfunctioning T-Con can lead to image blurriness, ghosting, or rapid flickering.
❌ Only half of the screen is displaying
🔹 If part of the screen is blank or darker, the T-Con ribbon cables or circuits may be defective.

How to Prevent T-Con Board Failure
✅ Use a surge protector to prevent voltage fluctuations
✅ Keep your TV clean to avoid dust accumulation on internal components
✅ Avoid applying pressure to the display panel to prevent damage to T-Con cables
✅ Turn off the TV when not in use for extended periods to reduce hardware wear
Repair or Replace T-Con Board – Which is Better?
The cost of repairing a T-Con board depends on the TV model and the type of damage. In many cases, T-Con board repairs are possible, but in newer TVs, replacing the board is often the better option.

Common T-CON Board Issues
- Blurry or Distorted Image: One of the most common problems with the T-CON board is image distortion or the display of blurry and unclear images. This issue could be caused by damage to the board circuitry or improper connections. Sometimes, the failure of components such as capacitors, transistors, or flex cables can lead to this problem.
- Black Screen or No Image: In this scenario, the TV turns on, but no image is displayed. This issue may be caused by a malfunctioning T-CON board or problems with the connections between the T-CON board and the display panel. In many cases, the T-CON board may completely fail, preventing it from transmitting signals properly.
- Vertical or Horizontal Lines on the Screen: Sometimes, you may notice vertical or horizontal lines appearing on the screen, indicating an issue with the T-CON board. These lines are typically caused by a failure in the image synchronization system or damage to internal components of the T-CON board.
How to Resolve T-CON Board Issues
Check and Replace Internal Components: If the problem is due to the failure of internal components on the T-CON board, it may be necessary to replace specific parts such as capacitors or resistors. This task requires technical skill and should be done by a professional technician.
Check Connections: The first step in diagnosing and fixing T-CON board issues is to check the connections of flex cables and wires. Sometimes, these connections become loose or disconnected due to pressure or exposure to moisture. A thorough inspection and tightening of these connections can resolve the issue.
Replace the T-CON Board: In cases of severe damage to the T-CON board, replacing the entire board is usually the best solution. In this case, make sure the new board is compatible with your TV model. Replacing the T-CON board requires precision and expertise, so it is recommended to have it done by a skilled technician.
Clean the Board: Sometimes dust or moisture can cause problems with the performance of the T-CON board. Using a soft brush and compressed air to clean the board can help fix issues like blurry images or similar errors.
