# 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.

# Schematics

Get hold of the schematics for your TV. Understand where the RGB and Fast Blanking signals go from OSD to the Jungle (Chroma) chip.

If you are building your own circuit, this diagram should help

# 14AF44

The below schematics is similar to 20AF44

# Performing the mod

# STEP 1: Remove the following components

# 14AF43

• Remove the following components

RGB resistors to the ground

• R141
• R142
• R143

Coupling capacitors to the ground

• C124
• C126
• C129

# 14AF44

• 14AF44 is similar to 14AF43. Remove the following components

RGB resistors to ground

• R141
• R142
• R143

There were no coupling capacitors to the ground that needed to be removed on my particular system. However, if you do find them in your TV, please remove them. Sometimes these coupling capacitors are mentioned in the service manual, but you don't find them on the actual board and vice-versa.

Coupling capacitors to ground

• C124
• C126
• C129

Did not remove C131 or C135. Removing them can affect the background of the OSD. Therefore, left them alone.

# STEP 2: Connect RGBs, Blanking and Audio

# 14AF43/14AF44

Connect the R, G, B and blanking (orange) wire. "X" is where the wires are connected.

# STEP 3: Build your mux circuit

Below 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 precalculated resistor values.

Buy your RGB mux board

Depending on the RGB/OSD stock resistors your CRT has, use the below inline resistors.

# STEP 4: Attach the female SCART connector to TV

Creating a SCART cutout and mounting it is an art. I have a dedicated section for it.

# Pictures

# Finished mod

SCART connector inside a Toshiba 14AF43. This location was a bit closer to the flyback. However, there was very minimal to no interference noticed.

Not the best cutout for the SCART connector. But, it is straight and holds steady.
