== Overview ==
== Description ==
The JVC AV-27D303 is a 27-inch CRT television released in 2002 as part of JVC's consumer television line. This model features a silver/gray bezel design and offers multiple input options including component video, S-Video, and composite connections. It shares its chassis and most features with the 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.


== Features ==
== Technical Details ==
* '''Component Video Input (YPbPr)''' - High-quality video connection for DVD players and gaming consoles

* '''Multiple Composite Inputs''' - Two rear inputs (Input 1 and Input 2) plus front Input 3 for convenience
* '''MTS Stereo with SAP''' - Multichannel Television Sound with Secondary Audio Programming
* '''3-LINE Digital Comb Filter''' - Improved picture quality and reduced color artifacts (uses Toshiba TC90A49P)
* '''HYPER-SURROUND''' - Enhanced stereo sound effect
* '''BBE Sound Enhancement''' - Audio enhancement technology
* '''Theater Pro D6500K''' - Color temperature adjustment for movie viewing
* '''181 Channel Capability''' - Full channel tuning support including cable channels
* '''V-Chip Parental Control''' - Content filtering with US and Canadian rating systems
* '''XDS (Extended Data Services)''' - Auto clock setting and channel identification
* '''Sleep Timer''' - Automatic power-off functionality
* '''ON/OFF Timer''' - Programmable power on/off scheduling
* '''Closed Caption''' - Built-in caption decoder
* '''Channel Guard''' - Parental control function
* '''Video Status Function''' - Display of current video settings


== Technical Specifications ==
=== Chassis ===
* '''Picture Tube:''' 27 inch (68.6 cm) measured diagonally, full square
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.
* '''Power Requirements:''' AC 120V, 60Hz
* '''Power Consumption:''' 105W
* '''Reception Format:''' NTSC, BTSC System (Multi-Channel Sound)
* '''Reception Range:'''
** VHF 2-13
** UHF 14-69
** CATV: 181 total channels (Sub Mid, Mid, Super, Hyper and Ultra bands)
* '''Speakers:''' 2" × 3-1/2" (5×9cm) Oval type × 2
* '''Audio Output:''' 1.2W + 1.2W
* '''Dimensions (W×H×D):''' 29 5/8" × 23 1/4" × 23" (75.2 × 59.0 × 53.1 cm)
* '''Weight:''' 70.8 lbs (32.2 kg)
* '''Remote Control:''' RM-C252
* '''Antenna Terminal:''' 75Ω F-Type Connector


== Design ==
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.
The AV-27D303 features a silver/gray 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. The JVC D-series logo appears on the front panel.

=== Tube Identification ===
{{CRT input|signal=Component|connector=RCA|count=1|location=rear|notes=INPUT 2 - YPbPr component video}}
The tube brand can be identified by the letter beside the serial number on the back of the set:
{{CRT input|signal=Composite|connector=RCA|count=1|location=rear|notes=INPUT 2 - can be used as composite or component}}
* '''R''' = RCA/Thomson (A68ADT25X)
{{CRT input|signal=Composite|connector=RCA|count=1|location=front|notes=INPUT 3 for easy access}}
* '''S''' = Samsung (A68QDN891X)
{{CRT input|signal=S-Video|connector=Mini-DIN 4-pin|count=1|location=rear|notes=Available on INPUT 1}}
* '''B''' = Goldstar/LG
{{CRT input|signal=RF|connector=F connector|count=1|location=rear|notes=75Ω VHF/UHF antenna/cable input}}
* '''M''' = Matsushita/Panasonic

== RGB Mod Information ==
=== Audio ===
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 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)


== Setup Tips ==
== Setup Tips ==
* If component video appears in black and white, access the setup menu and enable "V2 Component-In" for INPUT 2
* If component video appears in black and white, enable "V2 Component-In" in setup menu
* The default sharpness level is typically set too high, causing ringing artifacts. Adjust this in the user menu for optimal picture quality
* Default sharpness is typically too high - adjust in user menu for optimal picture
* To disable vertical edge enhancement (which artificially boosts contrast on vertical transitions for composite and RF sources), set LYC02 to zero in the 3L Y / C sub-menu of the service menu
* To disable vertical edge enhancement, set LYC02 to zero in service menu (3L Y/C sub-menu)
* The television includes I2C bus control for advanced service adjustments
* Front Input 3 jacks are under the front panel door
* The front Input 3 jacks are located under the front panel door - pull to open
* Unlike prior model years which would not save picture adjustments unless they were saved to the Choice mode, all picture adjustments for all modes are now automatically saved
 
== Service Information ==
This model uses a user's guide (document number LCT1145-001B-A) published in June 2002. The AV-27D303 shares its design and features with the AV-27D203, with both models using the RM-C252 remote control. The difference between AV-27D303/S and AV-27D303/R models is in the picture tube type.


== Known Issues ==
== Related Models ==
* Depending on the console/revision, dot artifacting ranges from slight to severe, and blending effects may be broken when using composite input
* [[JVC AV-27D203]] - Related D-Series model (same chassis)
* 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
* [[JVC AV-20D303]] - 20" D-Series model
* [[JVC AV-27D503]] - Premium D-Series with front component
