According to some non-regular repair shops, it seems to understand how to solve the problem reported this time, and it is possible to use it without problem even after exchanging the display with a third party. However, since it is necessary to upgrade the microchip in addition to the display exchange, if the display is replaced in the past and a problem occurs, it seems that repair is necessary again.
