I forgot a picture of the display. Here is it. The quality of the handycam is not so good.

There's no zebra strip there...
In the kit that Intersil sold in the 70's, the one with the 7106, the LCD was a DIL package, there was no zebra strip. The LCD was like this one:

But this isn't a picture of the original Intersil 7106 kit.

Well, that is interesting. I took another look at all of the 6010s I own (6010 10A version, 6010 20A version, Hung Chang 601 2A version) and all of them feature zebra strips connectors on the display.

Bad segments are usually a sign of bad contacts / missing signal line to that segment. I would start by checking the board for possible corrosion and obvious defects in the area where the pins join the glass assembly.

This looks a little bit like mine.
See the attached picture.
Do you think I can try to clean the contacts at the display with a Q-Tip and some alcohol?

Btw I couldn't see any oxidation at the contacts.

OK you can say: Trial and Error! But this isn't very useful if afterwards nothing is working anymore: Anyone here who has experience with cleaning the contacts of an LCD?
