Roberts ecologic 4: Solving the Mystery of the Non-Responsive Digital Control Board

This Roberts ecologic 4 looks brand new. The lights come on, but otherwise it’s completely dead. Why would a pristine digital control board suddenly refuse to wake up? We’re stripping it down,tracing power rails and testing for shorts. Let's find exactly where this logic circuit failed. We also encounter something unexpected in the middle of the video! I'm not an expert, but I do enjoy trying to fix things. If you enjoyed this video, or found it useful or helpful, please consider subscribing.
