your post does not make any sense it would be better to explain what the actual problem with the display. what do you mean by faulty segments.
what did the display look like when it was working properly.
what did the display look like when it was working improperly before you decided to mess about with the display.
when you switched on the scale before did the display come up all zero's as that is the normal start display.
I do not think you are really english because you do not write good english.
so what does your display look like now when you switch the scale on.
what is showing on the display. it could be perfect it may be working in a different mode. is there a black dot on the right and the word FIX in the middle of display.
