Samsung TV IR Remote Sensor Fault Identification Jan 16 2023 11 45 PM
My dad gave me an old Samsung smart TV that had some issues. Although the display was fine, there was no remote and the rear mounted manual control button was damaged. After purchasing a replacement IR remote I discovered the TV was failing to respond. By tracing the connections I was able to identify an open circuit caused by corrosion on the IR receiver data signal to the header pin.
