1 Answers
Here are the specific reasons why the air conditioning display screen of the Changan CS55 does not light up: 1. Power supply abnormality: Check whether the power supply of the display screen is normal. If the power supply is abnormal, replace the power supply module. 2. Poor contact: Check whether the cable connection is good. If the line connection is poor, it is necessary to promptly check whether there is a loose connection in the line, which causes the central control screen to go black. Simply reconnect the loose part properly. 3. Display screen damage: Check whether the display screen is damaged. Replace the display screen for testing. If it returns to normal, the display screen is damaged. If the power supply is normal and the cable connection is good, check the video output signal of the motherboard and replace the motherboard for testing.
