Toshiba 13A22

# Toshiba 13A22 RGB mod

This RGB mod should also apply for the below model

• Sansui TVM1316B

Also check the mod for Toshiba 13A21. It uses a different chassis than Toshbia 13A22.

This mod doesn't work for the below models. Below models use a single-chip. In the absence of OSD chip, RGB mod is not possible.

• Toshiba 13A23
• Toshiba 13A24
• Toshiba 13A25

# 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.

# PCB

Points where the R, G, B and Blanking (brown) wires should be connected are marked "X". Pink boxes show the resistors that needs to be removed.

# Performing the mod

# STEP 1: Remove the following components

Remove the three 680 ohm, RGB resistors to ground

• R102
• R103
• R104

# STEP 2: Connect R, G, B and blanking wires

RGB and blanking wires

# STEP 3: Connect sync, audio and ground wires

This set only supports mono audio. Therefore you would twist both grey and white wires together and solder it to the mono audio input. 1 kΩ resistors on the mux board will handle the channel mixing.

# STEP 4: Wire routing and full mod

# 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.

You can use either 1.3B board or the micro board. Both should work well on this set. 1.3B installation requires a bit more precise planning.

# 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.
