How to deal with the black screen of Buick GL8 central control screen?
1 Answers
When the car's central control screen appears black, it is most likely due to poor line contact. It is necessary to promptly check whether the lines are loose. Of course, it may also be because the power signal line has aged. You can try replacing it with a new one. It may also be due to prolonged use of the screen, causing a failure in the power supply module. It needs to be inspected and repaired at a maintenance shop or directly replaced.
