question 2: What should I do if the smart TV can't be opened? Your description is too simple to answer. If you can't open it, it's broken. If it's broken, you have to repair it. If it's not repaired, you have to replace it with a new one.
question 3: the smart TV can't be turned on. Press the standby button
question 4: the main interface of the smart TV can't be turned on. Generally, it is a system problem that can be solved by brushing. You can go to the znds forum to find the corresponding brushing package or contact the TV for after-sales solution.
question 5: what's wrong with the TV? fault analysis: the maintenance method of LCD TV when it fails to turn on and has a black screen should start from the power supply part and then go deep into the CPU circuit of the motherboard.
Samsung TV maintenance introduction said that there are several reasons why LCD TV can't be turned on:
l The power cord is not connected properly or the power adapter has no voltage output.
l The switching transformer in the TV has no voltage output, and the peripheral electronic components are abnormal.
l the power board is abnormal or the switching power supply module (IC) is abnormal.
l the remote control is out of power or damaged.
l the buttons on the TV control panel are damaged or leaked.
l the motherboard and CPU circuits are abnormal.
l the high voltage board, y board and buffer board are short-circuited.
Solution to the problem that the LCD TV can't be turned on:
(1) Check whether the 3V power supply of the power board is normal. If not, please check the front-end circuit of the power supply, such as transformer, stabilized IC, rectifier diode and filter capacitor.
(2) If there is 3V power supply, please check whether the power boards are powered by 5V, 24V and 12V; No, please check the small resistance and capacitance around the switching power supply. If yes, please further check the motherboard, CPU circuit, etc.
summary: the failure of LCD TV to start (except the failure of remote control related circuits) is mainly around this power supply part and then to the motherboard. When overhauling, we should start from the power supply board first, and then start from the motherboard after the power supply is ok.

It is a TV app launched in 15 years, which contains various video and non-video applications dedicated to TV, including live broadcast, Youku, Singular, Tencent, square dance, live game, etc. If the installation can't be opened, it is recommended to go to major TV application stores to download and install again. Because of storage and other reasons, there will always be cases of poor installation occasionally.
