jvc plasma pdp replacement?

Hi all.

I have two of these beasties, both JVC 42" plasmas made at about the
same time.

Unfortunately, one has a burned out PDP (has big black line on the
screen about 1/3 the way across and halfway down the screen) and the
other has an apparently fried controller board but the PDP looks fine.

I've got as far as determining that the base boards are not
mechanically compatible but they do use the same PDP, with essentially
the same pinout and specifications.

I can't seem to work out how to separate the PDP and uber-fragile
flexi cables with embedded LSI HV chips from the base plate with its
incorrect screw locations, undid about 24 screws and no go :(

Has anyone even attempted such a mammoth task? It seems feasible (the
LCD I modded is easy by comparison)

Thanks in advance.
