If your TV is not functioning correctly after installing the new power supply board, consider the following common issues:

| TV powers on but no picture/sound. | Loose internal cable connections (e.g., to main board, T-con board), other faulty components. | Ensure all internal ribbon cables and power connectors are securely attached. This issue might indicate a problem with another component, not the power supply board. |
