Looks like the common missing lines problem with these LCDs.
There is a flex cable connected to the LCD glass, from the PCB, possibly using some sort of anisotropic conductive adhesive. This seems to lose the connection with the LCD glass over time.
It is possible that it could be reattached with a combination of heat and pressure, but I don't think anyone has come up with a documented/proven method to do so, as in how much heat/pressure/time is required, and how to clamp it for pressure while heating it.
I found this info previously, in relation to how they commonly initially bond flex cable to glass with anisotropic conductive film in other non-MPC applications, no idea if this would be a good starting point in trying to repair a faulty MPC LCD glass to flex cable connection, or not, and whether this is similar adhesive to what is used in the MPC, or not...

If I ever have problems with my MPC LCDs, or find any faulty MPC LCDs to try it out on, I will give it a go.
