== 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 ==
=== Chassis ===
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.


== Overview ==
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 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.


== Features ==
=== Tube Identification ===
* '''Component Video Input (YPbPr)''' - High-quality video connection for DVD players and gaming consoles
The tube brand can be identified by the letter beside the serial number on the back of the set:
* '''S-Video Input''' - Enhanced video quality over composite
* '''R''' = RCA/Thomson (A68ADT25X)
* '''Multiple Composite Inputs''' - Two rear inputs (Input 1 and Input 2) plus front Input 3 for convenience
* '''S''' = Samsung (A68QDN891X)
* '''MTS Stereo with SAP''' - Multichannel Television Sound with Secondary Audio Programming
* '''B''' = Goldstar/LG
* '''3-LINE Digital Comb Filter''' - Improved picture quality and reduced color artifacts
* '''M''' = Matsushita/Panasonic
* '''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

== Design ==
=== Red Push Fix ===
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.
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 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
