You have a common problem. There have been very many posts on how to resolve issues with leaky hydraulic cyclinders, including how to remove and replace them and places which rebuild the seals for much less $ than buying new. Also, there is information on how to reset the controller which operates the top and is causing your lamp to flash. It's not the end of the world and it shouldn't be too expensive to repair if you are a bit of a mechanic. Use the forum search box to find previous solutions to these problems.
