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.
