A couple of my neighbours and my sister all have Centrex TVs, all are happy with them. They are cheap but there are worse.
The name isn't new, Centrex was an alternative brand name for Pioneer audio equipment. In fact I still have and use a Centrex 3-in-1 stereo, I keep it because the radio in it gets particularly clear reception, more modern radios with ICs instead of individual transistors generally have crummy tuners and we are in a weak signal area. Old radios work best here, I also have two old GE Superadios and nothing beats them.
My stereo is branded "Centrex by Pioneer."
Of course there is probably no connection with the new stuff, old brands are reappearing in cheap junk, I have seen "Pye" electronic stuff again recently, and Harvey Norman stores have resurrected the "Celestial" brand name on their cheap Chinese junk, not a good omen I'd have thought as that used to be the store brand for Waltons stores before they went broke.
