Design

The AV-20D303 features a black plastic bezel with bottom-mounted speakers. The control panel is located on the front right side of the television with volume, channel, and menu controls. Unique among its series, this model includes a headphone jack on the front panel.

RGB Mod Information

RGB modification information for this specific model is limited. The AV-20D303 may share similarities with other JVC 20-inch models like the AV-20D202, which uses the same board as the JVC AV-27230. However, JVC sets often digitally disable unused RGB signals via the Jungle IC's RGB SEL register, making RGB modification complex and potentially requiring microprocessor intervention. Since this model already includes high-quality component video inputs, an RGB mod may not provide significant picture quality improvements.

Setup Tips

If component video appears in black and white, access the setup menu and enable "V2 Component-In" for INPUT 2
The television includes I2C bus control for advanced service adjustments
The front Input 3 jacks are located under the front panel door - pull to open
When headphones are connected, the internal speakers are automatically muted
