# Theory

Sometimes it is nice to know the theory behind the mod. I have put this on a separate page. This shows how the various resistor values are calculated.

# Performing the mod

Now that you roughly know what needs to be done, prepare for the mod. Place the board on a comfortable place. Make sure you are not putting pressure on the flyback or other components. There are few wires that needs to be disconnected.

1. Degauss wire
2. Power wire
3. Ground wire attached to the neck board
4. Yoke deflection coil wire
5. Anode wire (this is the one with the rubber cap)
6. Left and right audio wires

# STEP 1: Remove the following components

• R020
• R022
• R024

# STEP 2: Connect RGBs, Blanking

Replace jumpers JW42 (green), JW43 (blue), JW44 (red) with diodes.

3V is the caluclated voltage for blanking. We can calculate 1.2kΩ resistance needed on the RGB mux board with a diode to produce the correct blanking voltage.

# STEP 3: Connect Sync and Audio

# STEP 4: Build your mux board

# STEP 5: Attach the female SCART connector to TV

Creating a SCART cutout and mounting it is an art. I have a dedicated section for it. How to create and mount a SCART female plug?
