A complete G8018 module that is not as clean as the previous one that was sold for $50 two weeks ago. This unit has the same issues that the red LED indicator light remains off when powered up, that indicates that one of the DC voltages is either missing or out of the range. Nothing appears damaged or overheated. If you are handy with the repair of this type of circuit board, this will be a great buy. If you find one or two components defective, I will replace it for just shipping cost. I have several working units that will be listed in the future.
