Hello,
I just got used A7riii and the touchscreen does not work. I have tried updating the firmware, resetting the camera multiple times, changing the setting that has to do with autofocus (yes I'm aware that you have to turn this function on, I've turned it on and off so many times already) I'm not sure what I'm missing. The touchscreen is just unresponsive. I've done everything short of sacrificing a goat. Has anyone else run into this issue before? The previous owner says that they never used the touchscreen so they were not aware of it. Please help me figure it out. It cost a lot of money.
Thanks!
