Daryl,
Are there any numbers anywhere indicating a J8 chassis? Check the rear of
the set on the model sticker. The chassis is usually included there. I have
a EMJ803 here.

Dave,
I guess the eyesight is amoung the things to go.  The only numbers I find on
the board is located at the rear edge with a paper tag is 0S0200189206872
and printed on the board on the right side edge is CH0019864-2000A.  I found
nothing starting with 00EMJ.
