The le700a and lx710a series are both X-type super crystal panels newly developed by sharp. Because the super crystal panel has high transmittance, it can penetrate the maximum brightness of the backlight to the front, so it looks like a mirror/

The backlight is only responsible for lighting, and the circuit lines are all on the panel. What determines the clarity is the resolution of the panel and the technological level of the panel. The backlight is added by the later module, which has something to do with the clarity

The backlight may not be on, that is, the backlight power supply (that is, inverter) is more likely to have a problem (generally, the lamp is not likely to break in three years), and the maintenance cost is about 50 to 100 pieces. 2. Maybe the driver circuit of the LCD panel is broken, causing the backlight and LCD panel to be unresponsive. After this repair, it is estimated that it will cost 100, 200 or even more. How to confirm what kind of situation it is: you say that you can hear music when you turn on the monitor, which means that the first possibility is relatively large.
