Toshiba 13A22

# Toshiba 13A22 CRT RGB mod

The Toshiba 13A22 is a 13" CRT display that can be easily modified for RGB input. Although it carries the Toshiba name, it was actually manufactured by Orion.

The set includes front-facing RCA inputs and an RF connector on the back.

I’ve only encountered this model in a dark grey finish. While aesthetics are subjective, I find this CRT more visually appealing than many other Orion-produced sets.

Sansui TVM1316B uses the same chassis and is also RGB moddable.

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

# 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.

# RGB mux diagram

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

# 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

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.

Compatible mux boards:

• RGB MUX BOARD KIT 1.4Bopen in new window

Highly recommended to use the variant B of the board or the micro board. Both should work well on this set. Mini mux board variant "B" installation requires a bit more precise planning. See pictures from this page to get an idea.

# 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.
