Y signal(RC238)
C. When “No signal” in Y/Pb/Pr signal (Component)
1) First check if other inputs are not working
=>If other inputs are not working, replace MAIN PCB
2) Checking waveforms with Color Bar Pattern(Using the oscilloscope)
-Main TP(COMP_Y) : RC238 near IC401(TOP)
-Main TP(COMP_Pb) : RC237 near IC401(TOP)
-Main TP(COMP_Pr) : RC239 near IC401(TOP)
=> If all signal does not appear, replace MAIN PCB.
Pb signal(RC237)
