Wondering if anyone else is seeing issues on optic tv in Alberta with PBS channel 140 it as if the signal is having issues were the color brightness is coming in and out. I figured this was my tv at first but only this channel has the problem.

I haven't noticed this myself. We don't watch live TV but record a fair bit off of PBS and the recording seem fine.
