There are face plate displays on car audio ( e.g.. CD players ) that when you disassemble the faceplate there are no hard wire connections between the display and the printed circuit board. I don't know what you call it but the bottom of the display has like two rubber strips that press against dozens of carbon points on the printed circuit board, this is how the display operates.
You have a similar display setup on Fluke 77 meters ( I don't know about other Fluke Meters ). How exactly does this rubber strips ( if they are rubber strips ? ) connecting to carbon points work? What are the strips called ? What is this type of connection called.
Can you clean the display rubber strips with rubbing alcohol if only part of the display works. Physically pressing on the display produces different effects on the display.
Your help appreciated.
Thanks in advance Denny B
