My smart TV remote control developed a problem where it would jump up and down the menu.
If you have this problem the way to fix it is to open up your remote control (pops open by slipping in to the bottom corner with blade or similar flat item and prize open) then taking the circuit board remove scroll wheel then spray WD40 or similar allow to soak in then wipe off surplus and gently tap out,replace scroll wheel and work it well by rolling it then wipe again and put back together....job done!
