Where can i get a replacement board for my tv

Yes, it's possible that the T-Con board in your Sony LCD TV may need to be repaired or replaced if it's causing vertical and horizontal white lines on the screen. The T-Con board is responsible for translating the digital signal from the TV's main board into a format that the LCD panel can display.
Before replacing the T-Con board, you may want to try some additional troubleshooting steps, such as checking all the cables and connections, performing a factory reset of the TV, and updating the firmware. However, if none of these steps resolve the issue, then the T-Con board may need to be replaced.
You can purchase a replacement T-Con board online or from a TV repair shop. If you're comfortable with electronics repair, you may be able to replace the board yourself by following instructions provided with the new T-Con board. Alternatively, you can hire a professional TV repair technician to replace the board for you.
