I have two roku tv's. I lost about 15 channels approx 4 months ago. I have done infinite Factory resets and channel scans. One tv got the channels back. The other has not after Tons of channel scans and factory resets...It did have them all at one time. Roku says its my cable company. Now I know that's not a true statement because one of the two tv's has the lost channels back. Anyone experience this? Ideas. They are cable channels.
