[Introduction] Automatically shutting down the TV may seem to many people to be a normal thing, but If the TV automatically shuts down frequently, would you still think it is normal?
Therefore, it must be dealt with in time. Let’s find out why the TV automatically shuts down?
Why does the TV automatically shut down?
Reason 1. Welding failure on the TV
Welding failure on the TV will cause the TV to shut down. The phenomenon caused by welding on the TV is that the TV shuts down irregularly. At the same time, it will automatically turn on after shutting down. After the TV is turned off, the user pats the case with his hand and the TV turns on again.
Reason 2. Radiation protection circuit
The radiation protection circuit of the TV causes the TV to automatically shut down. The phenomenon that occurs at this time is that the TV will shut down quickly again after being turned on, and it is also prone to inaccuracies. Scheduled shutdown.
What is the reason why the TV automatically shuts down
Reason 3. Overvoltage protection
When the TV power supply output voltage is higher than the set value, the overvoltage protection circuit will take effect. The TV's switching power supply will stop working. When the TV's switching power supply outputs voltage, it generates overvoltage protection due to the voltage increase. We can hear a sizzling sound when the power is turned on, and then the TV stops working.
Reason 4. Overcurrent protection
When the current load circuit of the TV causes excessive current for some reason, the TV's overcurrent protection will work and stop the TV power circuit from working. If the TV is under a slight load, the TV will automatically shut down after being turned on for a period of time.
