Precautions for the use of televisions.

Television sets are most afraid of uncontrolled switching. Each time the machine is turned on, the CRT filament is preheated to accelerate its aging.

Televisions are most afraid of strong magnetic field interference. If a magnetic object is moved in front of a phosphor screen, it will cause color discrepancy.

Do not use the fan and the TV on the same table, as the fan will vibrate and affect the life of the TV picture tube after it is activated. When the TV is working, do not wipe the screen with wet hands or a damp cloth, let alone splash cold water on the TV screen, so as not to explode and hurt people.

There is no sound on the TV, first check whether you have pressed the mute button on the remote control, increase the volume again to check whether the volume is too low at the 0 position.
