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

TA1310N has two sets of analog RGB inputs. One set is used for PiP (Picture In Picture) functionality. The other is used for Analog OSD input.

• R, G, B inputs via pins 3, 4, 5 (blanking on pin 6) is used for PiP. This input supports the standard 0.5Vpp analog signal input.
• R, G, B inputs via pins 7, 8, 9 (blanking on pin 10) is used for OSD. This input supports 1.25Vpp analog singal input.

Although it's theoretically possible to mux mod using the 7, 8, and 9 OSD inputs, doing so may result in a dull image if the voltage levels don’t match the chroma chip’s expectations. For better results, it's strongly recommended to use the PiP circuitry instead. While muxing with PiP might work, to keep things simpler and avoid complications, it's best to completely disconnect the PiP circuitry and directly inject the RGB signals.

# STEP 1: Disconnect PiP circuitry

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

Attach the R, G, B wires through the stock 0.1uF capacitors, or remove the stock 0.1uF capacitors and solder the R, G, B wires to the pins that are closer to the chroma IC.

# STEP 3: Connect sync and ground wires

# STEP 4: Audio and ground wires

# STEP 5: Build your mux board

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.
