If it only flashes once, then there is nothing to hear, and if it appears several times, it means that there is a problem with the TV.

This must be looking for customer service.,The reason why I bought you here?,I think it's the splash screen caused by the poor stability of the drive circuit.。

1. LCD TV flashing screen.

Causes. Splash screen was originally a professional term for computer displays, and it is now used in a wide range of display products. The product refers to the phenomenon that the screen flickers when the display is running, such as the screen shakes, horizontal and vertical bars, etc.

There are many reasons for this phenomenon, such as unstable incoming signal, unstable voltage, unstable connection of the display cable, problems with the LCD screen, and problems inside the TV. Sharp LED LCD TV flicker screen is also mostly caused by this. In one case, if the SharpLED LCD TV only appears once when the core is used, the phenomenon of flashing the lead screen will appear,Then it means that the problem of the TV is not very big,But we can't be careless at this time,In addition to the several reasons introduced before, it is easy to cause the TV to appear flicker,The poor stability of the TV's drive circuit will also lead to the problem of the flickering screen of the TV。

Second, LCD TV flicker screen solution.

LCD TV flashes,If it's a signal problem, then don't worry,Wait for the signal to stabilize, it will naturally not appear again; If the voltage is unstable, it is recommended to turn off the TV first and wait for the voltage to return to normal before use, so as not to damage the TV; As for the unstable connection of the cable, it is only necessary to turn off the power and connect it. These problems are easy to solve.

There are some complicated reasons for the flickering screen of LCD TVs. It may be that there is a problem with the LCD screen, the LED tube.

If it's broken, it needs to be taken to a repair shop for repair. The chip in the internal high-voltage board of the LCD TV is broken, resulting in the instability of the voltage output of the high-voltage board to the screen, which may also lead to the phenomenon of flickering screen, which must also be taken to the repair shop for repair. We are not professional TV maintenance personnel,Therefore, when there is a major failure of the TV and a problem with the TV,We can only turn to professional maintenance personnel,Of course, you can also contact the after-sales service of Sharp TV。

1. First of all, it causes a blue screen on Sharp TV.

This kind of failure, which takes a while for the signal to be available, is usually caused by a delay in the TV's CPU signal recognition circuitry. 2. It may be that the LCD tube in the display screen is damaged, or the high-voltage package for the LCD is damaged. 3. It may be because the identification circuit of Sharp TV Yuyan is faulty.

Suggested processing method:1、 If the Sharp TV is turned on blue screen,But after a period of time, it may recover by itself,CPU line delay,Just wait patiently for a while。 2、Accidentally touching the touch screen button is likely to be a signal source input Qinglu problem,At this time, you only need to set the remote control"Signal source"Input,You need to try them one by one,For example**、S terminal、VGA, etc.,If it's not a signal source,See if the antenna connection of Zaoqing TV is still normal,If it's not normal, you can reconnect the antenna,In this case, there are only these two possibilities。

3、If you can see a faint image when you look at the screen at close range,It is the internal lamp or LCDThe high-voltage package is damaged,At this time, it is recommended to contact the professional after-sales personnel of the TV for on-site maintenance。 4、Sharp TV's identification circuit is faulty,At this time, it is recommended to contact the professional after-sales personnel of the TV for on-site maintenance,Or contact the manufacturer to make an appointment for TV repair and replacement。

Sharp TV, the power light flashes when it is turned on, and the black screen does not respond.

1. After turning on, the power light should be lit stably. Its flickering phenomenon indicates that the circuit cannot enter the normal working state from the standby state; 2. The cause of the fault is mostly in the circuit, there is a short-circuit fault in the device, the protection unit acts, cuts off the power supply of the rear stage, and avoids the expansion of the fault and the damage to more components, and the power lamp flashes to notify the user; 3. This phenomenon will also occur when the standby circuit unit fails. At this time, the "power" infiltration wheel wake-up button on the remote control fails, and the main circuit cannot be started into the working state; 4. This kind of problem needs to be overhauled and dealt with by professional and technical personnel, and the customer service of the manufacturer can send maintenance personnel to inspect the forest branches or send them for repair.

1.Check whether you press the "Standby" button on the TV remote control to turn off the screen display and make the TV in standby, and press the "Standby" button again to wake up the TV;

2.If you are sure that it is not the standby state that causes the black screen.

It may be caused by the hardware failure of the TV, such as the failure of the internal switch circuit, the failure of the power supply system, the failure of the screen or screen cable, the failure of the motherboard circuit and other zero-calling components, etc., it is recommended to contact the after-sales service of the TV to carry out a comprehensive inspection and warranty of the TV to solve.

Workaround:1Check whether you press the "Standby" button on the TV remote control to turn off the screen display and make the TV in standby, and press the "Standby" button again to wake up the TV;

2.If it is determined that the black screen is not caused by the standby state of burning, it may be caused by the hardware failure of the TV, such as the internal switch circuit, the power supply system, the screen or screen cable failure, the motherboard circuit and other parts of the skin, etc., it is recommended to contact the after-sales service of the TV to carry out a comprehensive inspection and warranty of the TV to solve.
