When~~ headphones are connected, the internal speakers are automatically muted.		The JVC AV-20D303 is a 20-inch CRT television released in 2002 as part of JVC's D-Series consumer line. This late-era D-Series model features the GE3 chassis with Toshiba TM8812C- jungle IC. Unlike larger models in the series, this model uniquely includes a headphone jack - when headphones are connected, the internal speakers are automatically muted.

			== Technical Details ==

			=== Chassis ===
			The AV-20D303 uses the '''GE3''' chassis, featuring the '''Toshiba TM8812C-''' jungle IC. This late-era chassis represents a cost-reduced design and '''cannot be RGB modded''' - the component video inputs provide near-RGB quality for retro gaming.

			Unlike the earlier GE chassis, the GE3 lacks the E/W circuit, resulting in some barrel distortion that cannot be corrected. The 3-line digital comb filter provides quality composite and S-Video processing.

			=== Tube ===
			The AV-20D303 uses a 20" 4:3 CRT. The tube brand can be identified by the letter beside the serial number on the back of the set:
			* '''R''' = RCA/Thomson (A51KSV series)
			* '''S''' = Samsung
			* '''B''' = Goldstar/LG

			=== Audio ===
			The AV-20D303 uses a 1.2W × 2 stereo power amplifier with BBE Sound Enhancement and Hyper-Surround processing. The included headphone jack automatically mutes internal speakers when in use.

			=== Red Push Fix ===
			Late-era D-Series (Dx03) 2002 models may exhibit oversaturated reds. To correct this in the service menu:
			# Navigate to '''NTSC MAT''' → Set to '''000'''

			(Note: 2003-2004 Dx03/Dx04/Dx05 models with later revisions have no known red push fix)

	== Setup Tips ==		== Setup Tips ==
	* If component video appears in black and white, enable "V2 Component-In" in setup menu		* If component video appears in black and white, enable "V2 Component-In" in setup menu
			* Default sharpness is typically too high - adjust in user menu for optimal picture
			* To disable vertical edge enhancement, set LYC02 to zero in service menu (3L Y/C sub-menu)

			== 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.
