First time posting from Ky!
i have an issue that's popped up multiple times. This last time I believe a light curtain was broke causing an e-stop on the machine. The tech was called, and he couldn't get the machine to reset. When he checked the pendant, it was a white screen that wouldn't clear. He went to get help and when he came back it was a white screen that said "Action canceled Internet explorer was unable to link to the web page you requested. This page might be temporarily unavailable."
It's a Fanuc LR Mate 200id. When the power was cycled it came back up with a blank black screen. The only way to get it back was to do a cold start through the boot menu. This isn't the first time this has happened either.
Any ideas? Seems like a glitch but since it happened multiple times i doubt it is.
