Hi. I should've take a few pictures but completely slipped my mind.
After you have opened the remote, there are three clips with a total of six nuts holding the 'contact foil' to the board. At the bottom there's a connector and a little flexing, metal clamp connecting the foil to the board. Carefully remove this by sliding it towards the bottom of the board/remote and it should slip right off. Next use a thin xacto knife or similar and carefully lift the foil at a bottom corner, as it's glued to the board, so you can get a hold of the little lip that connects the foil to the board. I then used a cotton bud with isopropyl alcohol and cleaned the connector; not on-top of the foil, but between the foil and the board. I had to do this twice before it worked. Slip back the clamp and test and hopefully the connection between the board and the foil should work.
