Better ribbon cables would cost 2 more cents and the chinese do not want to spend that much :mad:
Yeah,
But back in the late 80's when Laptops were bulky and heavier.
The cabling going to the Monochrome screen was more like the 80 wire flat cable that was also used for PATA-IDE Hard drives.
Thus, I never had to worry about damaging it, unless there was a problem with a hinge that was broken.
And the cable was the only thing keeping the screen from coming off. :lol:

2 Liter Soda bottles, to make the shims'. :lol:

Disconnected the display ribbons, The entire rear dislodged from the front assembly with no hurdles nor effort, diffusers stayed in their place and sequence untouched, circuit boards still attached to the rear shell; LCD panel untouched !
Able then to test LED emitters; found two kaput. Ordered replacements and will update progress...
The dismantling part I was afraid of goofing with presented not a problem. :grin:
