# Sony G3F chassis CRT RGB mod

# RGB methods to try

# Method 1 (direct injection)

• Try injecting R, G, B signals directly to pins 47, 46, 45 directly
• Supply 5V via a diode (R9) and 1Kohm (R11) resistor to blank
• Use 75 ohm termination (R1, R2, R3)
• 0.1uF caps inline (R4, R5, R6)

# Method 2 (mux method) - only try if method 1 doesn't work

• Remove the ground resistors R343, R344, R345 (1k)
• Inject RGB in-between 0.1uF and 3.9kohm resistors on RGB lines attached to pins 38, 37, 36 in chroma
• Use 75 ohm termination (R1, R2, R3)
• Use 750 ohm RGB inline (R4, R5, R6)
• Use a diode on R9 to feed 5V
