  Good Afternoon,
                         This TV came in early this week. It's a Sharp 27L-S100 
with only a blue screen and no sound, OSD works, I inject a signal at 
IC201(IX3253CE)  IF input and the AGC voltage going to the tuner changes from 
7V to 0V and still no picture, But connect signal to tuner RF input and the AGC 
line stays the same. Sams on this one is 4231. I do not have the schematic, or 
pin out of IC201. Has anybody seen this problem? If not could someone email me 
the circuit around the jungle IC201 or better yet the sams 4231.
