I was downloading games from the eshop overnight because slow internet and when I woke up my Switch had a black screen (backlight ON). After trying to figure out what was happening I discovered that removing the SD card causes the screen to come back to life.
What could be causing this? I have tried different SD cards. And the SD card that was in there anyway is a legit Sandisk one from Amazon. It works fine in other consoles too.
There is a short on the larger capacitor above the SD card slot on the board but I don’t know what could cause that. The SD card slot is also in good condition and I have used contact cleaner and checked for bent pins / dirt. It looks as good as it can get.
Anyone had this before? Switch lite, works without SD card but black screen with backlight a few seconds after inserting SD card. Thanks
