Service Notes
TH-37PA20U TH-42PA20U (Service Hint SH-B19-04-06)
If the DG board is defective, order a complete tuner block
assembly (it contains DG board, H board, Tuners and wire
harnesses
Part #: TXAUX01QCSU), instead of just ordering the
DG board.
The new replacement DG board has a larger 6-pin connector at DG18 and is
incompatible with the original DG board, which had a small connector.
A running change to the DG board production was made. The size of the DG18
connector was changed and some software changes were made too. Because of
these, a new replacement DG board is not compatible with the existing G18 wire
harness and the interconnected H board software (To operate a new DG board
software, a new matched H board is necessary).

connector DG18.
