Organized the knowledge and experience of electrical appliances provided by netizens: it helps to prolong the service life of electrical appliances
(The more expensive TV does not mean the more durable)

1. Take good care of the heat dissipation of the TV: Blow electric wind or air conditioner
~Now they are ultrathin and bright (HDR10 up)
~ Pay attention to the place where the heat dissipation is good

2. Stable TV power supply: voltage regulator
~ The voltage in Taiwan is unstable (depending on the region), which may cause small parts to break.
(If one component is broken, it will not work properly)

3. To prevent electric leakage from being passed back to the TV: *The settop box should be turned off
~ Turn off the power of the upper box of the TV when it is not in use. If it is not turned off,
It may pass through the wire and indirectly affect the life of TV parts

***It is recommended that all HDMI devices that do not support cec linkage be plugged into an HDMI blocker, or use a UPS independent TV loop
It can avoid the 13 and 18 pin electric backflow; of course, it is better to have an independent circuit for the TV, or find a large wattage (similar to UPS) for the TV to connect, which is indeed the same as other electrical equipment and the TV current.
