0 td47 Posted January 21, 2021 Share Posted January 21, 2021 @Pawpaw If you have nothing plugged into the AV3 ports, then it is likely a hardware issue. Some older models had to have the main board replaced (possibly a "dry soldered joint" or galvanic corrosion issue), so that false signal were seen by the WebOS on some ports, hence causing a false pop-up.
