Please consider this as a precursor to an ERR D failure. Once ERR D occurs, you won't even be able to power on, and the entire power supply board will need to be replaced and repaired. It seems that ERR D can sometimes be fixed. If this doesn't fix it, the power supply board may also be faulty; in that case, please leave a comment for consultation regarding the power supply board. Operation confirmed. The image is for illustrative purposes. These are always available as repair/replacement parts. There are about 3 available, and we will reassemble them into a working unit and re-confirm normal operation before shipping.
