Sir Martyfoxy . . . . .
Hmmmmmmmm . . .that's being a somewhat older version.
I see the potential, of up to 6, of my marked in
RED X MARKED holes and their installed captive SM screw as holding this PCB against the front cases face bezel for the LCD display.
( Probably with the larger 4 ones the very closest to the display, as being the critical LCD clamping /pressure ones. )
Take note of the twentyish rectangular contact areas ### that need to have contact interfacing between the PCB propers typically gold flashed contacts on the identical superimoposed contact positions of the RED outlined portion of the YELLOW outlined LCD Displays glass panel.
They are being dependent upon spaced out . . . and alternatively insulated from each other . . . small strip clusters of conductive carbon fibers. Nicknamed Zebra strips, as the alternative blacks strips are the end to end conductive fibers and the white / or / insulator / products colors are being the insulative separators.
That is shown in better and even more exacting detail in the second illustration.
YOU MAKEE FOR ME . . .TESTIE - TESTIE TIME !
You now power up that already opened up / accesssible unit and observe its inactive segments on the LCD display.
If you will line up 4 equally spaced out fingers ( of your hand ) across the total width *** of that
RED marked in rectangle on the LCD display, now, I hope that with incrementing pressure downwards upon it, that you will then see the inactive ones then popping on and coming to life.
If so, we can fix, its deeper root problem..
It is strange, that I am seeing all of the rectangular contacts segments ###, but can't definitively see the interconnective ZEBRA strip due to your top camera angle of its shot.
Could you see if it is being visible from the left side and then take a side camera shot from the marked in YELLOW arrow direction ?
If you come out with all segments workable, I will pass on my own self developed, ever unwinding, procedure of 40 yrs of enhancements of your present situation.
Just now caught your . . . . .
Yes there is a zebra striped foam under the display . . . . at this post time.
The two relevant visual references are being included . . . . here . . . .
