I have a SONY 57" HDTV projection TV that is only about 4 years old.  I can't find the model number as it is on the back of the unit and it takes two men and a small boy to move it.  I read your article on the SONY Convergence problems & solutions and wonder if this info is current enough for the HD projection models.  I don't know if SAMS service manuals are available anymore.  I used to do a lot of hands on TV service including about 100 CRT monitors at NBC master control in Chicagto.  But, that was over 30 years ago and technology has moved on.  So I would appreciate any suggestions.  I  might add that the speaker grill on the front is removable, which allows access into the electronics area.  Thanks.  Bill
