== Description ==
The JVC AV-27D203 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. It shares the same chassis and features as the [[JVC AV-27D303]], differing primarily in cosmetic trim.
== Technical Details ==


== Overview ==
=== Chassis ===
The JVC AV-27D203 is a 27-inch CRT television released in 2002 as part of JVC's consumer television line. This model features a black 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-27D303.
The AV-27D203 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.


== Features ==
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.
* '''Component Video Input (YPbPr)''' - High-quality video connection for DVD players and gaming consoles
* '''S-Video Input''' - Enhanced video quality over composite
* '''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
* '''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 ==
=== Tube Identification ===
* '''Picture Tube:''' 27 inch (68.6 cm) measured diagonally, full square
The tube brand can be identified by the letter beside the serial number on the back of the set:
* '''Power Requirements:''' AC 120V, 60Hz
* '''R''' = RCA/Thomson (A68ADT25X)
* '''Power Consumption:''' 105W
* '''S''' = Samsung (A68QDN891X)
* '''Reception Format:''' NTSC, BTSC System (Multi-Channel Sound)
* '''B''' = Goldstar/LG
* '''Reception Range:'''  
* '''M''' = Matsushita/Panasonic
** 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 ==
=== Audio ===
The AV-27D203 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.
The AV-27D203 uses a 1.2W × 2 stereo power amplifier with BBE Sound Enhancement and Hyper-Surround processing.


{{CRT input|signal=Composite|connector=RCA|count=1|location=rear|notes=INPUT 1}}
=== Red Push Fix ===
{{CRT input|signal=Component|connector=RCA|count=1|location=rear|notes=INPUT 2 - YPbPr component video}}
Late-era D-Series (Dx03) 2002 models may exhibit oversaturated reds. To correct this in the service menu:
{{CRT input|signal=Composite|connector=RCA|count=1|location=rear|notes=INPUT 2 - can be used as composite or component}}
# Navigate to '''NTSC MAT''' → Set to '''000'''
{{CRT input|signal=Composite|connector=RCA|count=1|location=front|notes=INPUT 3 for easy access}}
{{CRT input|signal=S-Video|connector=Mini-DIN 4-pin|count=1|location=rear|notes=Available on INPUT 1}}
{{CRT input|signal=RF|connector=F connector|count=1|location=rear|notes=75Ω VHF/UHF antenna/cable input}}
{{CRT output|signal=Audio|connector=RCA|count=2|location=rear|notes=Fixed audio output L/R}}


== RGB Mod Information ==
(Note: 2003-2004 Dx03/Dx04/Dx05 models with later revisions have no known red push fix)
RGB modification information for this specific model is limited. The AV-27D203 shares similarities with other JVC D-series models (like the AV-27D200, AV-27D201, AV-27D500, AV-27D501) which may have similar board designs. 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 ==
== 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 television includes I2C bus control for advanced service adjustments
* Default sharpness is typically too high - adjust in user menu for optimal picture
* The front Input 3 jacks are located under the front panel door - pull to open
* To disable vertical edge enhancement, set LYC02 to zero in service menu (3L Y/C sub-menu)
* Front Input 3 jacks are under the front panel door

== Related Models ==
This model uses a user's guide (document number LCT1145-001B-A) published in June 2002. The AV-27D203 shares its design and features with the AV-27D303, with both models using the RM-C252 remote control.
* [[JVC AV-27D303]] - Silver bezel version (same chassis)
* [[JVC AV-20D303]] - 20" D-Series model
* [[JVC AV-27D503]] - Premium D-Series with front component
