Nintendo Switch Tablet Only - Only Works shop on TV, Unpatched

Product Name: Nintendo Switch Tablet Only - Only Works shop on TV, Unpatched
I am selling my Nintendo shop switch tablet only. It works fine when plugged into the dock but when you try to use it in handheld you cannot see the screen because the backlight doesn't come on. You can still touch the screen and it works but because the backlight doesn't work you can't see it unless you plug it into the tv. Otherwise it works great and is an unpatched low serial number switch so a great buy. No controllers or dock included, only the switch tablet is included.
