If you aren't too bothered about the looks, a cheap bodge/ repair might be to use clear heat shrink tube, max cost £3.10 for a metre. A lot cheaper then a complete controller kit replacement.
Your LCD isn't much different in size to my lcd2, buy a shrink size slightly larger then your lcd. Cut a piece to cover the whole screen, measure the screen width from bottom to top then the thickness of the screen and add them together, buy shrink a size or two bigger. A as long as the shrink is not more then 2 x the size of the above screen measurements added together it will shrink nicely.
Slide it on and then a slit to allow it to pass the cable and then warm it, it is 2:1 shrink ratio so the 120mm or even the 150 may be about right.
