Hello....

i recently purchased a Daimler Super 8 as my new toy. Loving the car so far. However when I purchased the car, the original head unit was not working so I purchased a refurbished screen.

tried installing the new screen and strange thing happens. It worked for few minutes, and it after 30 mins it started moving from top to bottom continuously Attached the pic. Has anyone experience the same? Screen was tested before purchased and it was all fine. So i presume screen was fine

Any Suggestions are welcome
