SOURCE: My TV Sharp 26 SB1 LCD PBS channel breaks up
Do any other OTA channels break up on this TV? Look through your setup options menu for a TV reset (memory or restore default or a similar command) . Do the reset and exit the menus (save the action on most TVs); then return and rescan the OTA channels.
On a different brand of TV this worked. The channel had broken up for several weeks; the reset was used when the channel finally became totally corrupted (no video on one sub-channel, no audio on the other).
Some tuners need a stronger signal to be stable; you may need an amplifier on your antenna.
I hope one of these ideas helps.
