Do a double rescan , disconnect the antenna coax from the Tv and do a scan , this clears out and resets the tuner for a fresh start/scan , now connect the antenna coax and scan for broadcast tv channels.
Digital transmitting equipment and digital receiver tuners can develop , digital glitches , if rescanning with out clearing out the tuner , the channel with the glitch is already there so channel with the glitch is just confirmed but not rescanned completly , so the glitch is still there.
And it is a good idea to scan for channels from time to time because new Tv stations/channels can begin transmitting with no notice.
What is the make and model number of the antenna and amplifier??
Please the Exact address to make a tvfool radar plot report.
Make the antenna height 25 feet or how high the antenna is.
