502 FS7 A7rii – Sony – Troubleshooting – randomly freeze and show black and white lines
The monitor is on the latest firmware and it did it with the older firmware too. When using the monitor it will randomly freeze and show black and white lines and can’t do anything but take the batteries out to stop it. Once this happens it happens a lot so staring it back up it will carry on. It does flashing purple or green screens or images flickering.
Hardware failure, replacing the mainboard appears to solve the issue.
