# Schematics

# RGB mux diagram

Prepare the mux diagram. If you are building your own circuit, this diagram should help.

# 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 RGB

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

# STEP 3: Connect Blanking

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.

Alternate location to connect blanking

# STEP 4: Connect Sync

# STEP 5: Connect Ground and Audio

# STEP 6: Build your mux board

This mod uses the RGB mux board. This is optional, but will make your mod easier and stable. You can also create the circuit presented in the schematics above without the board. Please also checkout the mux calculatoropen in new window to play with your own values.

# STEP 7: 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?

# Pictures

# Flux issue (pictures shared by Cristian Mendez KV-27FV300)

KV-27FV300 is pretty much the same as KV-36FS100 expect for an inclusion of a BC board and a subwoofer.

Below image shows flux all over the IDC pins.

When there is flux present, such as when resistors are removed on the main chassis or when soldering components on the mux board, it can cause a small amount of current to leak, leading to various kinds of interference. Below picture shows the white bar seen on the right side and the noise noticed.

After cleaning the flux and ensuring the ribbon cable is crimped properly, you can see the image is much cleaner and free of noise.
