Today when I powered on the device, I only got a black screen. The sound was playing, but there was no picture at all – not even the cursor. I removed the SD card and reinstalled the image that I had previously used successfully, but it didn’t help. The result is still a black screen with only audio playing.
I am using an LG 1080p TV. I moved the device to the living room and connected it to a newer LG QNED TV, and there I was able to get an image (I also updated the device at the same time), but on that TV there was no sound. I tried different HDMI ports on both TVs.
On the living room TV I tried changing resolutions and other display settings, but I still can’t get any picture on the main gaming TV. I also tried a different SD card. The power supply is the official Raspberry Pi power adapter.
EDIT I also tried using a different HDMI cable, but it didn’t help.
