Thanks for Stopping By This board (part) was pulled from a fully functional set with a cracked display panel. Please be sure to match the part numbers in this listing to the ones on your board(s). The same model sets may use different parts which may not be compatible. Could simply be a plug direction? Feel free to contact me if you have any questions. Sets are turned on before parts are removed. 100% refund for non-working parts. No refunds for parts that have been tempered with.
