What s going on with Hisense TV automatically shutting down?

Dear Hisense users, hello!

Don't know the exact model of your TV? Is it a smart TV? In what state does this issue occur?

If it's a smart application state,It may be a problem with the application,It is recommended to change to another application to try,Or go to the TV state to see,If it no longer appears,That's the problem of that application; If other apps also appear, it is recommended that you perform a factory reset function on your TV to try it; If there is a problem in the state of non-smart application,Please check whether the power supply is normal,If it still can't be solved,Please call Hisense national service**,Arrange a technician to serve you。

1. If there is only an occasional automatic shutdown, it may be caused by a power failure, a loose power plug, or a mispressed shutdown button of the remote control; Check them one by one and deal with them accordingly. 2. If there is frequent automatic shutdown, it is generally caused by hardware failures, including: (1) The switch circuit of the TV is soldered and damp and causes poor contact resulting in frequent automatic shutdown.

2) The power supply of the TV is abnormal, causing the TV to shut down automatically. (3) The short circuit of the internal circuit triggers the TV to start automatic protection, so it will automatically shut down. (4) The high-voltage instability of the motherboard circuit of the TV leads to automatic shutdown.

5) Most of the automatic shutdown of the TV is related to hardware failure, it is recommended to contact the after-sales service of the TV in time after the fault is found, and comprehensively overhaul and solve the problem of the TV's key burning.

There are several reasons for this problem: it may be that the power supply line is faulty, and it is recommended to contact professional maintenance personnel as soon as possible for the situation; It may be that the protection circuit action causes automatic standby, and this situation can be solved by checking whether there is a short circuit; It may be that the power supply is in poor contact, and it can be solved by replacing the power plug or power strip.

It is possible that the power supply line is faulty. It may be that the TV has been used for a long time, the power supply line is aging, or it is not properly maintained, and it has been bitten by Lubi mice, resulting in a poor power connection, and the TV will continue to automatically shut down. In this case, the problem can be solved by replacing the power supply line or repairing the power line.

It is possible that the protection circuit is operating and the automatic standby is caused. It may be that there is a short circuit in one of the parts of the internal circuit of the power supply, which causes the internal circuit of the power supply to start the action of the protection circuit, and there is a situation of automatic shutdown without congruent reading.

It is possible that the power supply is in poor contact. For this situation, it is generally a problem with the power plug or the power strip, for which you need to replace a power plug or replace the power strip.

Hisense TV calendar burns the cause of automatic shutdown after turning on the cause analysis and solution steps are as follows:1、It may be that the TV is set up with an automatic shutdown option,The TV will automatically shut down when it reaches the set shutdown time after turning it on,The solution to this situation is also relatively simple,You only need to use the remote control to enter the automatic switch off setting option,Eliminate the set automatic shutdown time or turn off the automatic shutdown function to solve the problem。 2、It is also possible that the circuit inside the TV has a phenomenon of virtual welding,Resulting in the automatic shutdown of the TV,In this case, you need to find the solder joint where the virtual welding occurs first,Then re-soldering it firmly。

3、It is also possible that when the input voltage of the TV exceeds the protection value of the set value,Or the instantaneous current of the TV is too large,It will cause the TV to turn off automatically。 In this case, it is recommended to temporarily turn off the TV, and wait until the voltage is stable**, so as not to cause greater damage to the TV.

The causes and solutions are as follows:

1. There is virtual soldering in the internal circuit.

Find the virtual solder joint and re-solder it with an electric soldering iron.

2. The X-ray protection electric lift circuit fails. He Dou.

The circuit is inspected and replaced if there is any abnormality.

3. The TV has over-voltage protection or over-current protection.

If the TV has over-voltage protection or over-current protection, you can turn off other electrical appliances and try to turn it on.

Maintenance method of Hisense TV

1. Turn off TV in time if you don't watch it.

Many people like to do other things while watching TV, or put on the TV at night, and turn it on all night when they fall asleep, which not only consumes electricity but does not save energy, but also easily burns out the inside of the screen.

In the past, CRT TVs were easy to burn out when they worked for a long time, and if LCD TVs operated for a long time, they were actually harmful to the screen. Hence in. When you're not watching TV, it's best to turn off the TV or reduce the brightness of the screen.

This can effectively prevent the TV from generating more heat when it is running, and the temperature rises, causing damage to the devices inside.

2. Pay attention to indoor humidity.

Generally speaking, the TV can operate normally at 30% to 80% humidity, but if the humidity is higher than 80%, it will cause excessive moisture inside the TV. If it is not treated for a long time, it is very likely to cause leakage and rust. Therefore, it is necessary to pay attention to it and do a good job of moisture-proof in the humid season.

If the machine has not been turned on for a long time, it can be used regularly for a period of time to promote the evaporation of water vapor through the heat generated by the operation of the TV.

3. TVs and refrigerators should not share a socket.

The starting current of the TV and refrigerator is very large, and the refrigerator is 5 times the rated current. The TV reaches 7-10 times the rated current, if it is started at the same time, the socket contacts and leads are difficult to bear, affect each other, and are prone to unexpected hazards.
