Nintendo Switch Repair, the game card cannot be read

Seeing "The game card cannot be read" every time you load a game on your Nintendo Switch? More often than not the culprit is a worn or damaged cartridge reader with bent pins inside the slot — not the game itself. In this guide we show you how to spot a failed cartridge reader, fit a replacement port, clean the contacts properly, and reassemble your Switch so it reads cards reliably again. And if you'd rather leave it to us, it's a repair we carry out here in Herefordshire.
