Is the automatic shutdown of the TV set top box after turning on a hardware failure or a software fa

Hello landlord, according to your description, the phenomenon of automatic shutdown of the TV set-top box generally has the following possibilities:

1. Shutdown caused by system problems, it is recommended to try to restore the factory settings first, if it cannot be restored, you need to flash the phone.

Second, if you have not flashed the phone, the standby function of the set-top box is turned on. How to turn off the standby function: Turn on the switch of the set-top box and the TV, and wait for the set-top box to start; After the set-top box starts, press the "Menu" button of the set-top box remote control; Enter the "Menu", then use the arrow keys of the remote control, find the "System Settings", and click the "Confirm" button of the remote control to enter; Find "Set-top box sleep" and change the option to "Off"; When you're done, press the "OK" button to save and exit.

3. The power adapter of the set-top box is abnormal.

Summary. 4. The failure of TV parts leads to automatic restart, such as poor contact of the motherboard circuit, moisture leakage of the high-voltage package, and unstable power supply of the motherboard.

What is the reason why the TV set-top box keeps restarting.

Hello,The set-top box of the TV keeps restarting Well,There may be several reasons:

1. The TV has poor heat dissipation, the room temperature is too high, and the working time is long, resulting in automatic restart caused by high temperature.

2. The power supply of the TV is abnormal, aging, and the socket causes the TV to restart automatically.

3. Automatic restart caused by poor hardware compatibility inside the TV.

4. The failure of TV parts leads to automatic restart, such as poor contact of the motherboard circuit, moisture leakage of the high-voltage package, and unstable power supply of the motherboard.

Extended Information: Here's the solution

1.Turn off the TV for a while and then turn it on.

2.If the software is incompatible with the system and causes a system crash, resulting in an automatic restart, it is recommended to check the recently installed software and delete it to solve the problem.

3.Automatic restart caused by failure of TV parts,For example, poor circuit contact of the motherboard、High-voltage package moisture leakage、Unstable power supply of the motherboard causes the TV to restart,In this case, we can only contact Skyworth's after-sales service for comprehensive testing and warranty of the TV。

4.Replace with a matching power adapter.

It's best to let him stop for a while, relieve it, and then see if it can be turned on, because the weather has been too hot recently, and it is very likely that it is overloaded, so it leads to repeated restarts.

Summary. 1. Over-voltage protectionIf the output voltage of the TV switching power supply is higher than the normal value, the over-voltage protection circuit will work and will automatically turn off the power supply. When the output voltage of the switching power supply rises and the overvoltage protection is generated, the high-voltage sizzling sound can generally be heard at the moment of start-up, and then the work will be stopped.

The output voltage increases due to the change of performance parameters of some components after power-on, so it automatically shuts down halfway. 2. Overcurrent protection If the current exceeds the normal value, the overcurrent protection circuit will also play a role to make the power supply circuit stop working. If there is a slight load, it may be turned on for a period of time before it will automatically shut down.

3. Automatic shutdown caused by virtual welding If it is an automatic shutdown caused by virtual welding, the shutdown time is irregular. It may turn on automatically after a shutdown, or it may require a pat to turn it on. After turning on the machine, it was normal again.

When there is a virtual soldering fault, disassemble the TV cover and carefully check the solder joints of the switching power supply and line scan output circuits, especially the components with large volume and high temperature.

TVs and set-top boxes turn off automatically.

Fourth, the X-ray protection circuit caused by automatic shutdown may also be the X-ray protection circuit caused by automatic shutdown, that is, soon after the start-up shutdown or irregular shutdown, at this time the voltage of the X-ray protection foot is higher than 3V, mostly for the external large resistance value deterioration, the foot can be directly short-circuited to the ground during maintenance.

The energy of the studio can be caused by a problem with the power module of the TV set-top box, or a failure of the movement. 2.There is a problem with the TV set-top box software:

For example, if there is abnormal operation or stuck, it may be that there is a problem with the TV set-top box software. 3.TV set-top box resource consumption is too large:

It may be that the TV set-top box has insufficient memory, or not enough storage space, or that the TV set-top box consumes too many resources during operation. 4.The temperature of the TV set-top box is too high:

It may be that the internal temperature of the TV set-top box is too high, causing the device to automatically shut down and restart. 5.The TV set-top box has poor reception:

Due to poor reception, the set-top box of the TV is frequently automatically shut down and restarted.

Summary. Hello! This can happen for the following reasons:

1. The setting of the set-top box.

2. There may be a problem with the audio receiving system of the TV.

Solution: 1. For the failure of the set-top box, the only way to ask the local cable TV network after-sales service to come to inspect it, or to get it and replace it with a new hall box in the business hall.

2、If there is no problem with the set-top box,It may be that there is a problem with the TV's audio ** receiving system,That is to say, the signal is not received directly after powering on,You must restart the search to receive the signal,This can only be detected and repaired by professional TV maintenance personnel。

After the TV is turned off, the set-top box will automatically turn off the signal, and the next time it is turned on, it will restart, how can I prevent the set-top box from automatically turning off?

Hello! Glad to be able to answer this question for you, please later! I'm speeding up the process of compiling answers that will help you and will get back to you in 5 minutes. I hope my suggestions and ideas can help you. Thank you!

Possible reasons why the set-top box will collapse and shut down after it is turned on:

1. The standby function of the set-top box has been turned on.

Standby off function method:

1. Turn on the switch of the set-top box and the TV, and wait for the set-top box to start;

2. After the set-top box is started, press the "Menu" button of the remote control of the set-top box;

3. Enter the "Menu", then use the arrow keys of the remote control, find "System Settings", and click the "Confirm" button of the remote control to enter;

4. Find "Set-top Box Sleep" and change the option to "Off";

5. After the change is completed, press the "OK" button to save and exit.

2. The power adapter of the set-top box is abnormal.
