Installation Notes for PVM-14N5 or 20N5
The RGBS function on the Sony PVM-14/20N5 is disabled by default. While it is technically possible to restore this feature by manually installing missing resistors, capacitors, and other components, the process is quite complicated and time-consuming.
Our RGBS modification kit provides a much simpler solution. It allows you to bypass the original disabled circuitry and connect directly to the video decoding chip, effectively re-enabling the RGBS input function.
To perform this modification:
- Remove/desolder resistor R305 (as marked with a red X in the reference diagram).
- Solder the white wire from the mod kit to point (25)
- Next, connect your RGB lines:
- Red wire → (28) → to the right side of capacitor C312
- Green wire → (27) → to the right side of capacitor C311
- Blue wire → (26) → to the right side of capacitor C310
These points correspond to R1, G1, and B1 inputs on the jungle IC. By connecting here, you restore proper RGB signal routing without needing to rebuild the entire missing circuit.
For the remaining connections in this RGBS modification:
- GND (Black wire):
Solder to the GND pin on connector CN401, as indicated in the below diagram. This ensures proper grounding for signal stability and noise reduction.
- VCC (Yellow wire):
Connect to the 9V VCC output on connector CP301, marked in the third diagram. This supplies power to the RGBS mod circuit.
The GND and VCC connections are essential for powering the mod and ensuring a clean, stable RGBS signal. Double-check polarity and solder joints before powering on your PVM.
This mod effectively activates RGBS on your N5 model, giving you vibrant, true RGB video performance while keeping the installation process clean and straightforward.
Now you’ll be able to enjoy your RGB scanlines on the 14N5!
