Default Re: Why did folk always unplug the telly at night?

What definitely caused cathode poisoning was the system switch in Thorn and other receivers.

When the customer finally got a "BBC2" aerial, and you switched over to UHF, the PC86 and PC88, which had never been used in anger, were invariably shot.

With TV rental of course, as long as the customer paid each month they could call us out as often as they liked, so the incentive for us was to reduce repeat calls, the most important statistic in the branch was to have a low CSA - average Calls/Subscriber/Annum.
