hottie_yankee this could be coming from the power supply board. It contains the high voltage inverters, and the biggest load is on the power supply. A faulty power supply can cause the screeching and shutting down. We would need to see what your boards look like and we could get you to try and measure some of the outputs, once we see what you got going on there. Post some good clear pictures with your QUESTION (edit it) Adding images to an existing question
