Know before you buy
You should match the part number printed directly on your original circuit board—in this case, TXNSC1PAUU or TNPA5351—rather than relying solely on the TV model number. Manufacturers often use different board versions for the same model, so verifying the part number is the most reliable way to ensure compatibility.
Yes, this unit comes as a complete set, including both the Y-Main board and the necessary buffer boards required for proper operation.
The 180-day warranty covers defects in the board's functionality under normal use. It provides protection against premature failure, giving you peace of mind that the component will perform as expected after installation.
This item is in used condition. Each board is sourced and inspected to ensure it meets the functional requirements for your Panasonic TC-P55ST30 television.
While the board is a direct replacement, television repair involves working with high-voltage components that can be dangerous. If you are not comfortable or experienced with internal electronics repair, it is highly recommended to have a professional technician install the board.
