一、加装后的测试 1.静态检查遥控板与电视机之间连好线后,通电试机前,应测量各主要测试点的电压值,如+12V电源、+5V电源、行场脉冲接线口、调谐电压输出端等端口的对地电阻。检查电源接线,确认电源无短路,连线正确后方可通电试机。 2.通电测试 (1)开机静噪电路应起作用、喇叭有声、光栅正常、字符显示清晰。 (2)按发射器各功能键,机器应有相应动作并且屏
First, the installation of the test 1. Static inspection After the remote control board and the TV with a good line, the power test machine, the main test points should be measured voltage values, such as +12 V power supply, +5 V power supply, field pulse Wiring, tuning voltage output port and other ports of the resistance. Check the power wiring, make sure the power supply is not short-circuit, the connection is correct before the power test machine. 2. Power Test (1) boot squelch circuit should play a role, the speaker sound, grating normal, character display is clear. (2) Press the transmitter function keys, the machine should have the appropriate action and screen
