例1 日立HF—G328DX彩色电视机一个月内接连烧坏电阻R_(901)(6W/6Ω)三只,其中包括10W水泥电阻一只,用一段阻值相当的电炉丝(1000W最好,利于压接)在水泥电阻上疏绕压接后,使用效果较好。例2 HFC 328DX彩色电视机出现三无故障,检修IC_(901)STR6020已损坏,换新IC后,将电源电压调致100V输入,只听偏转线圈“吱”的一声便又损坏IC。分析判断是电源电路不稳压所致。因为检修时未发现负
Example 1 Hitachi HF-G328DX color TV within a month after the burn resistance R_ (901) (6W / 6Ω) three, including a 10W cement resistance, with a considerable resistance of the electric wire (1000W is best, Crimp) on the cement resistance after the pressure splicing, the use of better. Example 2 HFC 328DX color TV three no trouble, repair IC_ (901) STR6020 is damaged, after the new IC, the power supply voltage is adjusted to 100V input, just listen to the deflection coil “squeak” it will damage the IC. Analysis to determine the power circuit is not regulated. Because the maintenance was not found negative
