RGBS with Horizontal Adjustment Mod-Kit

This kit provides clean, high-quality RGBS input with a built-in sync cleaner for the best image stability. It features a six-input RCA (Lotus) connector panel, premium electronic components, and comes pre-assembled with acrylic mounting plate and wiring harness — all you need to do is solder it to the corresponding points on your TV’s mainboard.

An 18-pin latching switch lets you completely disconnect the kit from the mainboard when turned off, restoring the TV to its original state without affecting normal functions.

This updated version also includes a horizontal position (H-Pos) adjustment knob, allowing you to fine-tune your image’s geometry for perfect centering.

Kit Includes:

• 6-RCA input panel with RGBS support

• Built-in sync cleaner for a stable image

• Pre-wired, easy-to-install kit – just solder to the mainboard

• Premium components and acrylic mounting plate

• 18-pin latching switch to bypass the mod when not in use

• Dedicated brightness control (potentiometer)

• No separate power supply needed — draws 12V directly from the TV mainboard

• Matte acrylic mounting panel for a clean, professional finish

Compatibility

• Works with Sony PVMs (Specifically designed for the PVM 14L1, 20L1, 14N6 and 20N6 models, no jungle IC replacement needed)

• Works with most consumer CRT TVs made before 2000

• Not suitable for CRTs made after 2000 with integrated “super ICs”

• JVC, Panasonic, and some other brands may require chip replacement or special handling

Important Notes

• The kit is not a scaler. It only enables direct RGB input (15kHz), not upscaling to higher resolutions.

• Picture adjustments (H-Pos, geometry) may require using your TV’s built-in service menu.

• The three blue trim pots on the board adjust RGB gain – fine-tuning brightness, contrast, and color balance.
