	== Description ==		== Description ==
	The JVC AV-27D303 is a 27-inch CRT television released in 2002 as part of JVC's D-Series consumer line. This model features a silver~~/gray~~ bezel design ~~and shares its chassis and features with~~ the ~~[[JVC AV-27D203\|AV~~-~~27D203]]~~.		The JVC AV-27D303 is a 27-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. The silver bezel design marks the transition from the earlier black cabinet D-Series.

	== ~~RGB Mod Information~~ ==		== Technical Details ==
	This ~~model~~ cannot be ~~easily~~ RGB modded ~~according to community reports. The~~ component video inputs provide near-RGB quality, making modification unnecessary for most users.
			=== Chassis ===
			The AV-27D303 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, making modification unnecessary for most users.

			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 Identification ===
			The tube brand can be identified by the letter beside the serial number on the back of the set:
			* '''R''' = RCA/Thomson (A68ADT25X)
			* '''S''' = Samsung (A68QDN891X)
			* '''B''' = Goldstar/LG
			* '''M''' = Matsushita/Panasonic

			=== Audio ===
			The AV-27D303 uses a 1.2W × 2 stereo power amplifier with BBE Sound Enhancement and Hyper-Surround processing.

			=== 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)

The difference between AV-27D303/S and AV-27D303/R models is in the picture tube type.

			== Known Issues ==
			* Depending on the console/revision, dot artifacting ranges from slight to severe, and blending effects may be broken when using composite input
			* Using a good external notch filter (such as the one in a RetroTink) and sending the signal to the component input would blend all dithering patterns and remove nearly all dot artifacts

			== RGB Mod Information ==
			This model '''cannot be easily RGB modded''' according to community reports. The chassis design is not readily compatible with RGB modification, and more importantly, the gains over the existing component input would be marginal due to this model year's very good component decoding. Since the AV-27D303 already includes high-quality component video inputs (YPbPr), it can display near-RGB quality video, making an RGB mod unnecessary for most users.

			* The default sharpness level is typically set too high, causing ringing artifacts. Adjust this in the user menu for optimal picture quality
