LCD is finished, what are the options if any?

Yeah it is not good news I know, good spec model bits the dust.....

@danj Going by the picture is this a 'Flexgate or 'Dustgate' issue with the cable or the actual LCD? And can opening and closing the display too much cause an LCD issue where no signal or power is going to particular area. I am considering to grab this dirt cheap as the tech guy has repaired these LVDS cables many times extending them so they don't rub anymore.

@livfe - Sorry no it's not FlexGate which was a 2016/17problem as Apple's engineers made the backlight flex cable a bit short with the needed thicker copper traces they became brittle! So as they moved they would fatigue!

DustGate is a more regional issue!related to the fine grit in the blown around dust. So in an arid and/or sandy area one would see this Vs a grass or forested areas as the soils (grit) would be held firm to the ground Vs deserts or large exposed soil. You will often see the black paint on the ribbon rubbed off and using a good magnifier or microscope (Michael Scope) you would see the erosion of the top insulator surface. So either the touching of the metal frame or the ribbon fine traces would short out and/or with a severe case fully cutting the traces so they are frayed out.

So we can remove both of these as your issue here as the symptoms don't align.

@danj That was not was I hoping for :( OK, thanks for clarifying this for me, the 2019 model then has 3 choices, A complete new display assembly, go headless, or die......

So while I'm not anti preventative we do need to have a clear understanding of the failure before we attempt unnecessary alterations.

The older Unibody systems (LVDS based signaling) was an analog carrier design (think back to the old days of Rabbit Ear antenna TV's you had to move about to get a good image on your TV) today's signaling is much more advanced! So while its also analog it's not a single voice trying to carry so much data as that tended to fail. Today we are multi-voiced! Using digital signaling. This is where Apple's work with DisplayPort morphed into eDP and iDP signaling! Think how a bus carries a bunch of people so when it gets a flat tire everyone onboard is stuck! Now if each person was on their own bike only one person would be affected by a flat tire. So 99% of the people would make it though! You've likely seen images of a boxy display image where blocks of data was corrupted. That's the flat tire! Here with iDP/eDP the short stub cable between the logic board & the T-CON is bad, Rare!
