dark lcd in my beckman 310 multimeter ...

[mlloyd1]

i have a beckman tech 310, the first digital multimeter i actually purchased, so it has sentimental value for me. but things i have also have to earn their keep.
anyway, the problem is the LCD display is bad - a big dark smudge in the middle.
anybody have ideas on replacement LCDs for these?
beckman instruments is not helpful; strictly medical tech now.

thanks,

Two of mine have the same problem. I had thought of trying thin aluminium sheet under the display. Don't have enough inspiration as I have other meters. Don't know how much it's feasible/possible

There is no way to repair a faulty LCD. Fortunately, they are mostly compatible (if you can find one with the same number of digits and additional symbols, and with the same number of pins).

The LCD looks black as its background reflector diffuses. If u see carefully, u can see the display. Only becomes difficult as it needs light to reflect from underneath for reading.

Green led underneath also does a good job.
