Some green corrosive substance is on many parts directly behind the I/R detector diode area. R401,CR104,R107,R133, Q901,C420 electrolytic. Trouble is, with my Partsfinder program, if I enter "CR104" for example under "symbol number", it will not bring up a part because I don't have the first number in the ID (such as CR4101, not CR401).But the board only has CR401.How the heck do I know the series these are a part of??? They are all mostly unreadable. Phil Bader -- Philip Bader Jan Phyl TV Inc. (estab. 1976) 3420 Recker Hwy.
