Shaun,
I suggest you contact http://www.bdent.com, B&D Enterprises,They have
excellent parts,spec sheets, and good advice.
Good l;uck.
btw, Emerson almost ALWAYS has wierd problems.You might also compare
other circuits using that reg and maybe change something to make yours work.
I have seen Emersons that looked identical on the outside,similat models and
COMPLELY different inside.This is a 25 inch direct view? al
