Panasonic Model TC-P50U50 I’ve tried everything and even had the cable guy tell me to get an HDMI splitter which didn’t work. Do I need to swap out the board?
@ststephen if everything is properly connected and if you tried different HDMI cables and tried a factory reset, then yes it sounds like a bad HDMI board. You’d be looking for the Panasonic TXN/A1SRUUS A-board available at places like this as well as many others.
