Read it is a part fix on the board with $30 and some soldering, where do you get the parts? The selection for Panasonic was not available but I still need an answer please.
@shoeppn 7 Blinks indicates: Driver SOS2 (SU/SD Connector DET) (SU/SD Scan and Logic IC) Boards to check are the SU-Board SD-Board Check for possibly a loose board connector, or an unalligned connector leading to the panel. There was an issue with loose boards causing some arching and shortening the SD board. Check for this on both side of the board. Post some images of your boards with your question. That will allow us to see what you see. Use this guide Adding images to an existing question for that.
