I have a TV in my home, which I haven’t used very much recently, so I thought of making a dust cover for it to protect the TV from dust. The shape of the box is fine.

The working process of the TV system is that the transmitting end converts each minute part of the scene into electrical signals according to the brightness and chromaticity, and then transmits them in sequence.

The characteristic of bathroom TV is that it is waterproof, so how is it waterproof?
