Insignia TV hangs while scanning channels
I have a 24-inch Insignia TV that will take a 12V input, so I use it in my trailer. Tonight when setting up at my campsite I raised and connected the antenna then scanned for channels. The little visual bar on the screen slowly made its way across and added "3" then "7" channels, then it stopped. It hung-- the remote control would not work and I had to reinsert the power cord to power cycle the TV. I've tried three times and I get the same result. It doesn't stop at the same place during the scan, but it's always after adding seven digital channels. Does anyone know what's going on here?
