Hallo every one This is one of my oscilloscopes. I have been using it for many years. Recently I noticed a circular shadow in the center of the screen,It looks like the glue that bonds the LCD has aged. I was wondering if there is a replacement for this model of LCD screen?Because the same model is very expensive The LCD module model is G321EV. Is there any other model of LCD module that can be a perfect replacement? Because if I buy the G321EV, after a period of use, the aging will appear again. I hope to completely solve the screen aging. |

You need to separate the screen from the PCB and see if there's any numbers printed on it. |

Electrically, it should work with the same screen size, resolution, and controller. But mechanically, I don't think it can be installed. It is better to purchase the same LCD panel or replace the polarizer. |

I guess it's because the glue that bonds them together has aged. If I buy the same model, I estimate that the same problem will occur again after a period of time, so I hope to completely solve this problem. |
