The title is true.
For some reason when the Switch heats up, only the LCD backlight stops working.
The system itself remains activated.
If you look closely at the screen, you can see that the video is on and only the backlight is off.
In case you are wondering, when the back panel stopped, the voltage on the four pins of the connector was the same as in the sleep state.
Of course the game sounds are still playing and I can go back to the home screen and do touch operations.
If I press the power back on at that time to return to the lock screen, the lock screen appears normal.
However, as soon as I unlock the system, it goes dark.
If I let the Switch cool down a bit, the Switch will show up correctly.
The LCD panel has already been replaced and the same thing happens even if I use another spare original casing.
Is there a problem with the backlight driver?
