Yesterday, I was taking multiple photos of a subject for a focus stack in live view in a hot room. After a bit, I couldn't change the settings for shutter speed, ISO or anything like that. Live view was still on at this time. Then I turned off live view and the screen didn't display anything. I couldn't reenter live view or enter file playback. I could still take photos. I took the card out and put it back in. Nothing happened. I took the battery out and put it back in. When I turned the camera on, the settings for date and time showed up and I could change the settings there, only once I had done that, I still couldn't do anything that requires the screen. I also couldn't enter the menu.
I noticed the screen was quite hot, so I took the camera to a cooler room. Once the screen had cooled, the camera worked... fine. I was wondering if the Nikon D5300 has a thermal shutoff for the screen or is it something worse? I also forgot to check if that was an error message in the viewfinder.
Thanks for reading and if you have any suggestions, please answer. Thanks again.
P.S: I also had problems before with the camera not taking photos or entering live view, while the screen worked. I thought this was something to do with the card. We had a replacement on the way, so, when it came, I formatted it and placed it in the camera. It seems to be fine now, but I've only had the card for a week or so. Just thought I'd mention this.
