The power adapter is actually a switching power supply, and its function is to take home 220 volts (foreign 110 volt AC power enters an ordinary LCD driver board can accept 12 volts DC (a single driver board accepts 15V24V). Generally speaking, 15-inch LCD power The average is about 20 watts, and the TV is only about 26 watts. Therefore, the general factory chooses standard output currents of 3-between 4. Reminder: the first one: see the input voltage above, av should generally be 100 -100; Second: Look at the output voltage and current value, generally 12 V, 3 a4a; Third: If you are a good DIY going abroad, also pay attention to the style of domestic power outlets, Chinese plugs, Korean plugs, plugs , European-style plugs and other large roses, well, what plugs can be used more than domestically, don’t worry about this.
