YES NG OK Go to (A) flow. In the case of (C1) _ DTV, NO Check if there is normal. Is there any problem? Check signal intensity. Check IC304 used in the composite & S-video out and IC303 used in the component YPbPr & RGB analog. NO END YES NG Check...tuner part. OK Check HD 2 interrupt request signal. YES Check analog buffers. Check Power Supply part. Check if system clock 27MHz comes from IC206(9), when signal is input stream. IC203(F11) 3-27 It is not OSD problem. NO Is there decoding problem? (B) YES Is analog component on the Mute mode? Check DVI output.
