The heater control display finally decided to go into permanent missing pixel mode last week so I fitted the zebra strip I'd had lying around for several years when pixel problems first arose. (Which promptly fixed themselves once I'd gotten the strip and made sure the battery was always well up. Magic!)
Unfortunately I can't get a full set of display elements to come up. Despite several cleanings and fitting tries the bottom half (ish) isn't co-operating. A bit of judicious thumb pressure on the bottom of the screen brings up some signs of life suggesting the zebra strip isn't settling flat on the contact areas of PCB and display.
Any ideas as to how this could be fixed? Looks to me that the zebra stip I have is little too tall and a little too thin to work properly in the space available hence it could tilt when the display is tightened down. Are all the zebra strips the same size or could my early E-Bay sourced one be wrong?
