Replacement main board for the Sharp LC-37D40U.
The main board handles signal processing and control for the set.
Cross references include KD640 and DUNTKD640FM06.
Please make sure there is #5 inside the triangle. This indicates the version. Having a TV Part Board that shares the same part number but whose version is different will not work or display artifacts when installed.
Confirm the model and board number on your original part before ordering.
