My old faithful Fluke 83 from the mid 1990′s had a display problem that is sometimes described as ghosting. It was much lighter in color than normal. Some segments were nearly faded completely away. I found this thread. All I did was take a polymer eraser, the white ones from many mfr’s, and cut it to a more pointed shape. Then carefully cleaned the places on the circuit board where the lcd makes contact. These contacts were made visibly brighter by the eraser. I then cleaned up the contacts for the push buttons as well. They were never a problem, but worth the cleaning since I was in there anyway. I cleaned the carbon tips of the buttons gently with the eraser as well. I never took the old original pink elastomer off of the lcd nor did I clean the lcd. Just gently cleaning with the polymer type eraser of the pcb contacts was all that was needed. The display has never looked so bright and crisp!! We will see how long this repair lasts!
There is a replacement kit on Ebay from a vendor named A-fluke. The kit these days is about $24USD. It supplies instructions and the newer gray elastomeric parts for the 80 series of Fluke meters.
