As @Wiener_Demeanor said the multi meter is using zebra strips and yours is the more problematic pinned version. Have a look at the solder job on the pins but 99.8% of the time the issue is the pin to the glass connection. They actually lay down a conductive path of aluminum (vapour deposition) across the glass to the pin. You can see the tracks if you angle the light just right.
Typically the problem is the corner pins (more mechanical stress). I used to repair these years ago with a conductive epoxy (crazy expensive). Have a look around you might find something suitable.

I got some shit going on with my Nikon CoolPix L32 digi cam. Was taking some pics of the foggy frosty hoar frost covered trees on the way home from town 3pm yesterday. Dark spot on the bottom of the screen and figured it was dead area on the LCD at teh back of the camera but was on the pics when I downloaded to my PC. Gets darker as zoom is applied. Nothing on the lens and I cleaned that to be sure.

All I can think it’s a dead spot on the CCD is it called? Hoping it was a random bit of dust that got on it somehow I rapped the camera with a bic lighter to see if it moved but nada. I know I can replace the LCD if I want but the CCD? Really like this little camera too as it has manual white balance so I can calibrate it to get good pics under HPS light. Was only $100 a couple years ago but still.

Here’s a pic showing it at fairly high zoom.

Time to start hunting for info on the web I guess.
