Yesterday, channels 7.1, 7.2 and 7.3 played normally, along with the rest of about 100 OTA channels on WMC. Today (23 July 2015), channels 7.1, 7.2 and 7.3 display the no signal screen, but the rest of the channels play normally. Oddly enough, channels 7.1, 7.2 and 7.3 continue to display all green bars in WMC's Digital TV Antenna Signal Strength tool. Guide data remained current for those channels, too. Those 3 channels continue to play fine using the TV tuner, just not on WMC and they won't record.
Suggestions on how to rectify this problem? Ran Set Up TV Signal; Scan for More Channels and PC reboot, but no change. FYI, I'm not aware of any changes made to WMC since yesterday, except Guide updates.
3 OTA digital channels quit on WMC

Had to uninstall, then, reinstall WMC to recover the 3 missing OTA channels. Used the following procedure:
Here are the steps:
Keep in mind that you will lose your recording schedule. You will just need to set it up again once you are finished with this process.
1. Uninstall Windows Media center from the Programs and Features section of Control Panel. Under the Media Features section, unselect Windows Media Center and Windows Media Player. Click OK. Let Windows reboot.
2. You need to delete 2 directories that hold Media Center databases and other info. These directories remain after uninstalling WMC and need to be removed so that WMC does not pick up old settings when reinstalled. First, verify that you can view hidden files and folders. You will not be able to find the folders listed below if Windows is using hidden folders. To do this, open Control Panel and select Folder Options. Click the View tab. Under the Hidden files and Folders section, select "Show hidden files,folders, or drives" Click OK. Open File Explorer and select your C: drive (or whatever drive Windows is installed on). Open this directory: Users->(Name of current user)->AppData->Local->Microsoft. Delete the eHome directory. Next, Go back to your C: drive. Open ProgramData->Microsoft. Delete the eHome directory.
3. Reinstall Windows Media center from the Programs and Features section of Control Panel. Under the Media Features section, select Windows Media Center and Windows Media Player. Click OK. Let Windows reboot.
4. Open Media Center and choose Custom Setup. Run through the setup process. In the TV section of the setup, the guide data should come down properly and the channels will be scanned and listed like they should.
Hope this helps!

Turned out the problem was not caused by WMC, but by the broadcaster:
Hope their transmitter repair doesn't trigger another need to reinstall WMC.That is quite interesting. Glad you found a workaround. In the meantime, I have found the problem on our end to be transmitter related and we will have the replacement components installed Tuesday in the early morning hours.
Thanks!
