2 Channels ABC 6 & Fox 28 on my spectrum app will be playing then system unavailable will come up. I can do a system restart and they will work but it happens again. Spectrum came out, checked everything, put a new modem in, had me install the spectrum app on my phone and watched those 2 channels and it didn't happen. He says it was my TV. Updates are current & I periodically clear the cache. The TV is a year old this month. Any ideas? This just started within the last 2 months.
