We plugged our energy meter into a mains socket then plugged our 10″ CRT TV into it. We had already entered our electricity price into the meter so it could give us a direct readout of running cost. The TV was left in standby when not is use as it had no front-panel mains switch, only a standby switch. The TV was used normally, around 2 hours a day over a total test period of 180 hours and 32 minutes.

NB Over the test period the power wasted while the set was in standby was about the same as that used for watching programmes. We turn it off at the socket now!
