sem2106芯片去保护方法

三星P2250/2243EWPLUSPWM 芯片型号为SEM2105

去保护的方法是：对地14脚,如果还不行的话,可以短路该芯片的1脚和4脚。

另附：高压板常见故障现象有：

a、暗屏；开机就是暗屏，按动 POWER 键时，指示灯有变化，说明驱动板还能工作；

b、亮一下就灭：开机时正常点亮，几秒钟就灭，灭的时候是暗屏，说明高压板保护了；

c、亮一段时间以后才灭：开始一切正常，几分钟或几十分钟以后暗屏；

d、关机白屏：开机都正常，关机以后还白屏；说明高压板关不断；

e、图像、背光反复亮灭闪动：一般是高压板电路有元器件击穿软击穿，导致电源板保护；

f、背光偏红 ：灯管老化或者高压板供电不足、输出电压偏低；

g、灯管半边亮半边暗：灯管老化、断线或者高压板供电不足、输出电压偏低.
