Sansui TVM1316B

# Sansui TVM1316B

This mod should also work for the below models

• Toshiba 13A22
• Panasonic CT-13R37S

Please note that not all versions of Sansui, Toshiba, Panasonic's are RGB moddable, even though they might look alike from outside. Later models use a single-chip. And in the absence of OSD chip, RGB mod is not easily possible.

# 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 RGBs, Blanking and Audio

# 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.

# 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.
