Well.. the old display was easy to remove
without removing the front panel.
Four nuts and two cable assemblies.
So far so good.
Was able to remove the bezel by straightening
the holding tabs. Wow.. this is going to be
easy. NOT.
After removing the bezel what is left is
LCD glass with a loose card stock type of
material, same size as the LCD glass below it.
Below this is what looks like a translucent
material with a reflective backing below that.
The backlights is embedded on both the
top and bottom edges of this substrate. The backlight consist
of a row small light thingy.
OK.. so far so good.
I was thinking of putting a row of LEDs
on the two opposite sides which don’t have
any light, shining it through the edge
of that translucent substrate. Now to find
the right size LEDs.
So I decided to reassemble the display
so that I don’t loose anything.
WHAMO… the LCD glass needs to be tight
against that translucent substrate. WHY..
Otherwise you get missing lines and/or rows.
Took the display apart again, checked everything twice.
Reassemble, tighten those tabs on the bezel
real good. Not as many lines missing now but disappointed.
Gave up.
BUT, I need that flat cable for the new
display. Double side pc with a solder wick,
nope.. solder sucker … nope.
Difficult to remove a ribbon cable while
trying to heat up 20 pins simultaneously.
Didn’t work..
My desperate solution, short of purchasing
a Hakko desoldering station, was to slice
the cable lengthwise about an inch from
the display board and heat/pull each of
those pins individually. Whew.. close call.
Soldered to the new display, put back into the rig, like new.
So.. A near catastrophic experience that I don’t recommend.
Those Youtube videos I was relying on, was a bust with
this type of display. Maybe I overlooked something but
won’t do this again. Lesson learned.
Hope someone can glean from this experience.
thanks for the bandwidth.
