I have nintendo switch that is not getting any display while on handheld mode but the backlight is on and the touchscreen works. When i placed it on dock it showed the display on my TV… i tried to do a lot of things even reset but no luck what could be the possible issue?
You may have a problem with your ribbon cabble connection on the motherboard. Has your nintendo Switch got in contact with water at any point in time?
I would guess LCD, ribbon cable or connector problem. And what @raulgbcr said…any liquid damage?
