The reasons for the intermittent display of the car navigation screen are: 1. Poor contact or aging of the power signal cable; 2. Faulty power supply module due to prolonged screen usage; 3. Defective circuit design requiring inspection, repair, or replacement at a repair shop. Methods to remove scratches from the car screen include: 1. Gently rub along the direction of the scratch with a soft pencil eraser until the scratch disappears; 2. Mix household white vinegar and distilled water in a 1:1 ratio, fold a soft cotton cloth, dip it into the vinegar solution, and gently wipe along the direction of the scratch.
