Summary. To confirm whether the TV is in the upgraded working state, wait for a period of time for the TV to turn back on; Second, it is also necessary to eliminate the digital signal failure of the TV to prevent the set-top box from crashing in the process of working.

To confirm whether the TV is in the upgraded working state, wait for a period of time, and the TV will turn on again; Second, it is also necessary to eliminate the digital fingerprint signal failure of the old TV to prevent the set-top box from crashing in the process of working.

1、In the actual opening process of the TV,If there is the latest TV working system after meeting certain requirements and standards,The TV will carry out automatic system upgrade,Most of the TV upgrade time is about 10 minutes,In the process of upgrading, there will be its own corresponding automatic restart function,If there is still no restart,You can try to shut down and restart,Electric sail TV machine re-select the upgrade operation。 2. It is also necessary to check the input and output of the TV signal to eliminate the problem of digital signal transmission. In the process of actual signal transmission,The set-top box of the TV must ensure the normal working state,To prevent the occurrence of a crash,When necessary, this is the problem of the internal system working and the worm,It is necessary to bury the set-top box in time to power off,At the same time, the power switch can be restored normally。

If it still can't be solved, it means that there is a corresponding problem with the internal system of the TV, and a special maintenance personnel is required to reinstall the corresponding system. Realize quick repairs to the internal systems of the TV.

Hope the answer is helpful to you this time.

Unplug everything.

Plug it back in.

It is possible that the remote control fails to start, or it may be that there is a problem with the settings, and the solution is as follows:

1、Click the number button on the TV directly,See if it can be turned on,If it can be turned on,It means that it is a problem with the remote control;

2. Turn off the TV and turn it back on.

3. When the above methods do not work, you can consider restoring factory settings.

There are two ways to recover: one is to press and hold the selection key and the screening key, and the other is to press and hold the selection key and the program key;

4. If the above methods do not work, it may be a problem with the Biwu section circuit board, and it is best to go to the after-sales service for maintenance.

The TV is in standby mode, the indicator light is on, and it cannot be turned on. After checking that the TV switch power supply is normal, but in a protective state, there is no output voltage, when cutting off the output transformer 110V input point, connected to the false load has 110V normal voltage output, if there is no voltage output, most of them are line pipe breakdown, or high-voltage packet, ground breakdown, not protection circuit action. You can measure the resistance of the line tube to the ground, or disconnect the collector of the open tube at this time, and then connect back to the high-voltage package power supply foot, and do not remove the bulb.

If the high-voltage packet is short-circuited to ground, the bulb will not light up. Also take a good look at the reverse capacitor.

The TV won't turn on after normal standby:

The first step,Think about whether the control keys of the TV panel worked before the TV had a problem,The keyboard will generally oxidize and fail after a long time on TV。

If the panel control key worked before the problem,Now you can't turn on the machine no matter how you press it,Then it must be a problem with the TV,If it's still under warranty,Contact the seller for warranty。 If the warranty period is over, you have to go to the professional maintenance department to repair, generally it is a problem with the power strip, and the user can not take care of himself.

If the panel buttons have failed before the problem, then there may be a line of collapse that may be due to a problem with the remote control, resulting in the inability to turn on.

Two tips to know if the remote control is out of order:

1. Turn on the photo function of the mobile phone, and aim at the ultraviolet emission head in front of the remote control (like a transparent LED bulb, but it is not visible to the naked eye) Then press the key on the remote control, if the remote control is normal, you will see the ultraviolet emission head on the mobile phone screen emit a light purple light! Try it if you don't believe it.

2. Another way is to turn on an ordinary radio and keep it on the spine normally. Press the remote control button, if the remote control is normal, the radio's signal will be interfered with, producing a "click" sound. It's obvious!

If the remote control is broken, then you can contact the seller to replace the remote control!

There is a problem with both the load section and the line scan. Because of the short circuit fault of line scan,The power supply part is out of a protective state,If the TV is a secondary failure,It is very likely that the power supply part will be burned out。

General reasons and solutions for the TV that can't be turned on standby:

1. If the TV is in standby, you can press the standby button and power button on the remote control to wake up the TV, or you can press the channel + channel-key on the fuselage to wake up the TV;

2. If it is invalid, it can basically be judged that the hardware of the TV is faulty; For example, the internal circuit of the TV is short-circuited, the high-voltage package is faulty, the picture tube is faulty, the motherboard switch circuit is faulty or other parts are damaged, etc., there may be a standby problem, it is recommended to contact the after-sales service of the TV for a comprehensive inspection and warranty of the TV.

3. It may just be a mistake in the start of the TV system, you can turn off the TV by powering it off, and then turn it on after a period of time, and it can return to normal.

4. If the TV is restarted and the boot screen is repeated, it may be that the TV system has collapsed, and it is necessary to contact the after-sales service of the TV to arrange professional and technical personnel to come to the door to brush the new system for the user to solve the problem.

5. The hardware failure of the TV may also lead to the repetition of the boot screen when booting up, and the system cannot be entered, such as the internal circuit power supply voltage is unstable, the processor or memory is faulty, the motherboard chip or other parts are faulty, and the TV needs to be repaired by contacting the after-sales service of the TV to solve the problem.

6. Generally, you need to turn on the remote control and click the menu.

7、Restart it to install a third-party application You can install a dangbei application market on the device。

8. In addition to the power cord and plug-in board problem, it means that your TV is out of order.

9. If the indicator lights are not on, the fault is in the pre-amplifier of the power supply, the CPU is short-circuited, or it may be in the re-amplifier, like a short circuit of the load. There are many types of pre-stage faults, such as fuse failure due to switch breakdown, or chip short circuit in the case of post-stage faults.
