Telus TV +

I'm in a brand new house, brand new subdivision, with 2 brand new TVs. Had a Telus technician come and install new NAH, wifi mini boost etc. He gave me his personal cell for support issues and  did come back once to replace the TV mini to correct a blurry guide. Now he tells me to just turn it off and on. I've had  to unplug  both TVs at least once a week to restore  lost audio or correct blurry display. Tough for a 79 year old woman to climb on a chair and pull out a 65" TV for a reset. Sometimes I get the green "loading" circle for quite awhile before the system starts. The built in TV Apps are fine - always have good sound & sharp display. I've had Telus optic for years and never had an issue with the older PVR's etc. It's not a big house & I pay for 500 mbps internet but  Technician installed everything close together and in the basement which I realize is not ideal.  Appreciate any suggestions before phoning support
