What's wrong with the white image of the 42-inch Lehua LCD TV?

You can replace a small chip of the logic board AS 15-G, or the screen voltage is wrong. If it is still in the after-sales period, directly find the after-sales solution. If it has been guaranteed, it is suggested to replace a small chip AS 15-G on the logic board first, and measure the screen voltage at the same time. LCD TV can be properly maintained to prevent excessive production accumulation. Thunderstorm weather, pay attention to lightning protection and moistureproof, indoor humidity should not be too high. You can't cover the machine with cloth, at least not when it is turned on, because the LCD screen will generate too much heat when it is working.

Do not touch the LCD screen with corrosive liquid.

First, don't get too close to the stereo. It is best to keep it above half a meter. Because there is this sticker in the stereo, you should use magnetism to interfere with everything and reduce the interference to the TV.

Second, avoid the LCD TV being in standby state for a long time. When the LCD TV is in standby state, some internal components are still working. If it encounters lightning, it is likely to damage the TV. Therefore, it is best to unplug the TV when not in use.

Third, it is best to turn on the TV for about half an hour every day, so that the inside of the TV can work every day and keep the inside of the LCD TV in advance, which can improve the service life of the TV.

Fourth, when not in use, be sure to turn off the power supply and reduce the brightness of its display, which can prolong the service life of the TV set. Television should be kept away from light and dust. When the TV is not turned on at ordinary times, it is best to cover it with a TV, but the TV cover must be removed when it is used, so that the TV can get good heat dissipation.

Fifth, don't put other communication equipment next to the TV. LCD TV itself displays pictures by inserting signals. If it is disturbed by external signals for a long time, the picture quality of TV will be reduced and serious snowflake phenomenon will appear.

Sixth, don't scrub the LCD TV with too much water, and don't wipe the screen with rough fibers. It will damage the color and appearance of the LCD TV for a long time. It is best to gently wipe it with a professional liquid crystal cleaning solution.

Seventh, the LCD TV should not be too close to the humidifier. Water vapor will erode the LCD screen for a long time and affect the color.

Eighth, avoid hard objects or blunt objects directly hitting the screen. The LCD screen is fragile.

Ninth, LCD TV is a national three-guarantee product. If you encounter after-sales problems after watching TV, please contact the manufacturer in time, and the professional after-sales personnel of the manufacturer will come to check and repair. Don't open it yourself. On the one hand, improper disassembly will further damage the TV.
