Digital OTA Channels lose color

[intrepid]

I have a tv which receives analog channels and digital ota channels for about 2 months. I can pick up my PBS ota digital channels from about 50 miles away from the tower, as well as a couple of ota digital channels from a local NBC affliliate. I get good signal strength and receive a crisp clear picture on the digital channels. However yesterday my digital ota channels are in black and white, while my analog channels are still in color. My signal strength has not changed on my ota channels and I haven't made any changes to my system. Any suggestions as to what may be happening would be greatly appreciated. Thanks

Try to reboot the receiver (Unplug, wait 30 secs, plug it back in)

It sounds like your Cb and Cr cables are unplugged.
