ADI3114显示器有一个种常见故障，现象是屏幕无光，电源变压器发出“吱吱”声，而且电源指示灯有一闪一闪现象。看起来似乎是电源问题，但实际上通常是由于帧芯片IC3（如图）中TDA1675损坏所引起。故障分析：这种现象问题一般出在TDA1675芯片上。当TDA1675的芯片发生内部短路或
The ADI3114 display has a common problem when the screen is dim, the power transformer squeaks, and the power light blinks. It may seem like a power problem, but it’s actually caused by a broken TDA1675 in the frame chip IC3 (pictured). Failure Analysis: This phenomenon is generally on the TDA1675 chip. When the TDA1675 chip internal short circuit or
